Mysterious Creatures From The Sea Bottom

Perhaps the only place left on Earth that has remained unexplored and virtually untouched by man is the ocean bottom. But with the development of techniques and technologies that may be the only mystery of nature slowly begins to unfold.


Fifty-two marine explorers accomplished the first comprehensive biological survey of the seabed during a 10-week expedition aboard the Polarstern, a German research vessel. Among the findings was a new species of epimeria, an amphipod crustacean, which was sampled near Elephant Island, Antarctic Peninsula.

Antarctic Amphipod Crustacean

Scientists collected hundreds of specimens, and identified 15 possible new species of shrimp-like amphipods, and four possible new species of organisms related to coral, jellyfish and sea anemones, which will be analyzed to determine whether they in fact are newly discovered species. Here you see a new giant Antarctic amphipod crustacean, belonging to the genus Eusirus, sampled by baited traps off the Antarctic Peninsula during the Polarstern expedition.

Antarctic Ice Fish

The 52 explorers on the powerful icebreaking research ship were logging finds from icy waters as far as 850 yards off Antarctica — an area rapidly changing in fundamental ways. Here you see the Antarctic ice fish. It has no red blood pigments and no red blood cells as an adaptation to the low temperature. As a result, the blood is more fluid, and the animal saves energy pumping blood through its body.


Ascidiacea is a class in the Urochordata subphylum of sac-like marine invertebrate filter feeders. Ascidians are characterized by a tough outer “tunic” made of the polysaccharide tunicin, as compared to other tunicates which are less rigid.


Corals are marine organisms in class Anthozoa of phylum Cnidaria typically living in compact colonies of many identical individual “polyps”. The group includes the important reef builders that inhabit tropical oceans, which secrete calcium carbonate to form a hard skeleton.


Sea spiders, also called Pantopoda or pycnogonids, are marine arthropods of class Pycnogonida. They are cosmopolitan, found especially in the Mediterranean and Caribbean Seas and the Arctic and Antarctic Oceans. There are over 1300 known species, ranging in size from 1 to 10 millimeters to over 90 centimeters in some deep water species. Most are toward the smaller end of this range in relatively shallow depths, however, they can grow to be quite large in Antarctic waters.

Sea Cucumbers

Sea cucumbers are echinoderms from the class Holothuroidea. They are marine animals with a leathery skin and an elongated body containing a single, branched gonad. Sea cucumbers are found on the sea floor worldwide. There are a number of holothurian species and genera, many of which are targeted for human consumption. The harvested product is variously referred to as trepang, beche-de-mer or balate.

Top 10 Most Beautiful And Colorful Fish

The mesmerizing feeling of warm sun rays leaning down into  tropical waters, and breaking back through the water’s vivid facade as it rebounds off the glistening scales of a rare fish provides an experience that stays in one’s memory for a lifetime. I thought I’d share some of the most beautiful species that I know in the waters. There are in the order i consider them the most vibrant and beautiful, since, beauty is, ofcourse, in the eye of the beholder.


The Mandarinfish or Mandarin dragonet , is a small, brightly-colored member of the dragonet family, which is popular in the saltwater aquarium trade. The mandarinfish is native to the Pacific, ranging approximately from the Ryukyu Islands south to Australia.

2.Juvenile Emporer Angel Fish

The emperor angelfish, Pomacanthus imperator, is a species of marine angelfish. It is a reef-associated fish, native to the Indian and Pacific Oceans, from the Red Sea to Hawaii and the Austral Islands.


A Lionfish is any of several species of venomous marine fish in the genera Pterois, Parapterois, Brachypterois, Ebosia or Dendrochirus, of the family Scorpaenidae. The lionfish is also known as the Turkey Fish, Scorpion or Fire Fish. They are notable for their extremely long and separated spines, and have a generally striped appearance, red, green, navy green, brown, orange, yellow, black, maroon, or white.

4.Clown Trigger Fish

The clown triggerfish, Balistoides conspicillum, is a triggerfish from the order Tetraodontiformes. This reef-associated fish is commonly found in the tropical Indo-Pacific


A nudibranch  is a member of what is now a taxonomic clade, and what was previously a suborder, of soft-bodied, shell-less marine opisthobranch gastropod mollusks, which are noted for their often extraordinary colors and striking forms. The clade Nudibranchia is the largest clade within the heterobranchs, with more than 3,000 described species.


Symphysodon are a genus of three species of cichlid freshwater fishes native to the Amazon River basin. Discus are popular as aquarium fish and their aquaculture in several countries in Asia is a major industry.

7.Mantis Shrimp

Mantis shrimp or stomatopods are marine crustaceans, the members of the order Stomatopoda. They are neither shrimp nor mantids, but receive their name purely from the physical resemblance to both the terrestrial praying mantis and the shrimp. They may reach 30 centimetres (12 in) in length, although exceptional cases of up to 38 cm (15 in) have been recorded. The carapace of mantis shrimp covers only the rear part of the head and the first three segments of the thorax. Mantis shrimp appear in a variety of colours, from shades of browns to bright neon colours. Although they are common animals and among the most important predators in many shallow, tropical and sub-tropical marine habitats they are poorly understood as many species spend most of their life tucked away in burrows and holes.

8.Moorish Idol

The moorish idol, Zanclus cornutus, is a small marine fish species, the sole representative of the the Family  Zanclidae  in order Perciform. A common inhabitant of tropical to subtropical reefs and lagoons, the moorish idol is notable for its wide distribution throughout the Indo-Pacific. A number of butterflyfishes  closely resemble the moorish idol.


Clownfish or anemonefish are fishes from the subfamily Amphiprioninae in the family Pomacentridae. About twenty-nine species are recognized, one in the genus Premnas, while the remaining are in the genus Amphiprion. In the wild they all form symbiotic mutualisms with sea anemones. Depending on species, clownfish are overall yellow, orange, reddish, or blackish, and many show white bars or patches. The largest reach a length of 18 centimetres (7.1 in), while the smallest barely reach 10 centimetres.

10.Rainbow Parrot Fish

Named Parrot fish because of their calcareous bird-like beaks. Parrot fish use these beaks to crush and eat the small invertebrates that live in coral. Much of the sand and sea floor of coral reefs are actually remains of meals from the parrot fish, they chew the coral, eat the invertebrates and spit out the leftover calcium. In most species, the initial phase is dull red, brown or grey, while the terminal phase is vividly green or blue with bright pink or yellow patches. The remarkably different terminal and initial phases were first described as separate species in several cases, but there are also some species where the phases are similar.

The key is to learn how to set up a fish tank before you get too far ahead of yourself.

When you have decided that it is time to learn how to set up a fish tank the first thing you need to know is there are lists of things you are going to need to get started. Of course you are going to need the fish tank, next you will need a filter system, then a heating system and the right kind of gravel will also be needed, then water and a fish tank lid with a light in it. Another important thing you will need to consider is ornaments for the inside of your tank. This could be anything from driftwood, bought fake ornaments to live or plastic plants.

Below you will find six simple steps as to how to set up a fish tank. These steps are just to help you scratch the surface and you should be responsible enough to find the materials to get the exact information that will be needed. At least this will give you sort of a list of how the steps should be followed.

1. Before you learn how to set up a fish tank you will need to make some decisions. The biggest one of all will be what kind of fish you decide to keep. Different fish require different care. For example fresh water fish are totally different from salt water fish. While fresh water fish are easier to maintain, the salt water fish are much nicer to watch but harder to bring up. Studying your options here can be part of your homework.

2. Of course from your research and the list above you should know exactly what you need by now. It’s time to head over to your pet store and purchase the items that will be needed now that you have an idea on how to set up a fish tank. Just remember you have done your research so be careful as to what the people at the store try to up sell you to.

3. You are finally home and the time to set up the tank has arrived. Probably the most important decision you will make is where you will put the tank. You want it somewhere so it can be enjoyed by everyone and the coolest thing about a beautiful fish tank is that it can easily be worked into the decor of a home. The next thing you will be doing is adding the filter, along with the heater, gravel and finally the water. Now there are two more things to do in this step. The first will be to turn the heater to the appropriate temperature and get all the decorations placed inside. Finally you can put the lid on and walk away.

4. I know you are excited because you took the time to learn how to set up a fish tank but your patience is still required. You want to wait at least a week; two would be better before adding any fish to the aquarium. I know this sucks but really it is what you must do. This allows time for the temperature to be adjusted to exactly what you need, it allows you to find out if the filter is working and of course by this time you will also know if there are any leaks in the tank.

5. The time has finally come. You have waited so patiently but now you get to go out and get your fish. I would imagine by now you have an idea of what kind of fish to get. The biggest tip I could give you is to make sure you pick breeds that are going to get along with each other. Of course only buy an amount that’s suitable to the size of your tank. Be sure to pick fish that look healthy. Of course keep the price inside your budget as well. Most importantly choose fish that you are going to enjoy watching for a long time to come.

6. Now that you have done all your homework and you learned how to set up a fish tank there is still one more very important step. That step is to make sure you learn everything about maintenance. Make sure you feed the fish, check the filters and so forth and so forth. Preventative maintenance will go along ways towards keeping your fish alive a lot longer.

Keep your lid on the tank. It has 2 very important purposes. It keeps the fish from jumping out and it keeps the water from evaporating too fast.

Make sure you have sufficient ornaments for those fish that you buy which may be shy. This will help them live a much easier life, thus they will live longer.

So now that you have read this article you can move forward into the fine details as in how to set up a fish tank.


How to Take Care of Fish – 3 Great Beginner Tips

Nobody knows how to take care of fish automatically but with a few tips and pieces of advice, you’ll soon see that it is not difficult at all. In this article, I’ll tell you how to make sure you have happy, well behaved fish that live for a long time.

Tip 1 – Mixing Fish

Every species of fish is different. Some prefer to live on their own. Others are more social. Some will fight if put together – this is quite common for males but can even occur between two females.

Fish sharing an aquarium should generally be of a similar size. If you place one fish with another that is much smaller then it stands a good chance of losing a few fins and may even be eaten, even if you are feeding your fish well!

Often, it is a good idea to mix regular tropical fish with bottom feeders like catfish. As they do not compete for food (tropical fish tend to aim for the surface of the watter) then these species are usually highly compatible tank mates.

Tip 2 – Environment

Fish don’t like to be stressed. Some species are totally unsuitable if you have children, for example, as the stress can kill them.

Fish should generally be kept away from large groups of people, loud music and direct sunlight.

You should also find out what kind of water your fish like. Many people overlook the temperature of the water and also its acidity.

If you don’t regulate both of these carefully then your fish may get stressed, live a short life and fail to breed.

Tip 3 – Cleaning

Cleaning is a necessary part of keeping fish. Again, how often you clean depends on the species of fish you are keeping. Regardless, the good news is that you don’t have to move your fish out of the tank to perform cleaning.

Obviously, when the water looks murky then the water needs changing. However, some species demand more water changing than others. For example, many cichlid experts will perform a water change on a daily basis.

There is a lot of bad advice out there that recommends changing the water once per week. For most species, this is not enough. You should be looking at doing water changes between three and six times per week.


Troubleshooting Dirty Aquariums

After setting up a freshwater aquarium it’s now time to simply relax and watch your mini ecosystem thrive. Right… not entirely! Once you setup freshwater aquarium begins the true challenge of maintaining it. You’ve taken time in choosing the right combination of fish, plants and other elements to make a beautiful creation. But maintaining it at a pristine condition is a constant battle so you’d better start learning the necessities. Hen you start a fresh water aquarium, the real battle is in maintaining it!

So what happens when you find your supposedly little haven of relation slowly being engulfed in dirt and algae? You fight back and regain its former glory!

Don’t worry! Setting up a freshwater aquarium is easy, so does maintaining it – that is if you know what to do. You must first uncover the reason why your aquarium is dirty. But the most common cause is dirty water. As simple as diagnosing as such, the answer is likewise simple – just get a filter. This will solve your problem regarding dirt and discoloration. The filter will sift out the impurities in the water and it will maintain its relaxing mood. The only draw back here is that you have to change the filter every 3 to 4 weeks.

Another cause of aquarium problems is algae. These little nuisances can cause your aquarium to discolor and even affect the health of the plants and the fish in your tank. The best way to battle this predicament is to employ the help of algae eaters (Plecostomus). This is the best known protector against parasites in freshwater aquariums. So always keep in mind this mighty warrior when you start a fresh water aquarium.

Also, murky water may be the result of over feeding your fish. Always provide adequate amount of food in order to keep them healthy as well as keep your aquarium looking good. Another trick is to use distilled water or bottled water if you want your aquarium to be crystal-clear. It’s a little too much especially when the cost of distilled water or bottled water is a bit pricy. But for those really serious about how their freshwater aquarium looks, then this is a small price to pay.

Cleaning your aquarium at least every two weeks can help maintain a great looking setup. Remove all decorations, transfer fish and plants, and everything in it. Make sure to scrub the glass surface with a clean sponge to get rid of any stuck to it. Once you are done, setup your freshwater aquarium as if you’re starting all over again.


Guppies – Live Birth Fish

t is true that most fish lay eggs. Guppies and Mollies are not one of these types of fish. They can have up to between 9 and a couple baby fish at the same time. They come in a variety of colors. If their tank is a little bit warmer than normal, it increases their mating capabilities. In order to effectively breed guppies you should a birthing tank that hooks onto the side of your large aquarium.

When labor is over then you can collect all the babies and put them in their own little tiny tank. Make sure that you do not over feed them. If the water turns cloudy then change the water immediately. The recommended way to change the water is to dump the water from the baby tank into the large aquarium where the eco-system’s algae eaters will eat all the gunk. Put the baby aquarium deep into the large aquarium and let the fresh water come in. The babies will go flying!

You should change their water about twice a week to make sure that they survive in ideal conditions. If one of the babies dies, then dump it into the big aquarium so the algae eaters can have a feast. If you do not have a baby aquarium then make sure to have lots of hiding places for your babies so they do not get eaten by other fish. This can be accomplished by putting tall grasses in corners or a wad of netting in a corner as well. The babies can go in and out of the holes but the larger fish will not be able to do so.

Waiting for your pregnant fish to have babies is so exciting! If you have never bought guppies before then you should really give it a try. The are rather inexpensive to purchase and they are a ton of fun!


Learn More About Goldfish Anatomy

Goldfish are the most popular of fish and probably one of the most beautiful pet fish. We all know how a fish looks like and most of us know the name of the body parts. It will be fun to learn more about the use of every part on the goldfishes body.

Are you ready? Here we go:

Dorsal Fin – this helps the goldfish have stability in water. Usually goldfish like Common or Comet have an upright dorsal fin. On the other hand, “Fancy” goldfish may have a longer dorsal fin or even without one. An example of long dorsal fin is the Veiltail variety, while goldfish like Ranchu and Lionhead do not have a dorsal fin.

Tail Fin(Caudal Fin) – This helps the fish swim forward in the water. Goldfish types are determined by the type of the tail fin. There are two types of tail fin: single tail (Common, Comet, Shubunkin) and double tail (all Fancy).

Gills – these help the goldfish breathe. They are located on both sides of the water and they extract the oxygen from water and into the blood.

Anal Fin – helps the fish swim upwards and it is located before the tail fin.

Pectoral Fins – these help the fin swim forward and backward in the tank. They are located behind and under the gills.

Pelvic Fins – fish use these for stability and steering. They are located on both sides of the fish, behind the pectoral fins and the anal fins.

Lateral Line – This helps locate movement in the water and avoid obstacles.

Eyes – these help the fish see. Most goldfish have a very strong visual acuity, but goldfish like the Moor, Bubble Eye, Telescope Eye or Celestial Eye have a limited eye sight. It is best not to have pointed objects in your aquarium or they might get hurt.

Mouth – it helps the goldfish to eat and take water

Wen – this is common to Oranda, Lionhead and Lionchu goldfish. This is the skin that grows on top of their head. It looks like a “hat” and it is very beautiful. It has a raspberry-like look.

There you have it. These are all the body parts of the goldfish. These are a most know for every goldfish owner and enthusiast.


How to Set Up a Home Aquarium – A Beginner’s Guide

You might be interested in setting up an aquarium at home or at your office. An aquarium can be incredibly interesting in terms of both decor and amusement. A new aquarium will provide a focal point in any room. In addition, keeping fish can be a relaxing and enjoyable hobby. There are many reasons why people become interested in setting up a home aquarium.However, it is very disheartening when the fish suddenly die. If you have small children, they can become very upset. Even adults who own fish that die become upset at their demise. Even worse, the aquarium is then left to gather dust in the room or in a corner of the basement. Rather than going through a series of disappointments, it is important to learn how to set up a home aquarium properly. This way, you will never have to deal with the disappointments that can arise from improper aquarium set-up.The first and most important factor you should keep in mind when setting up a new aquarium is the location. Make sure you pick the right spot for your aquarium even before you set it up. Otherwise, it can be a real hassle to have to move an aquarium that is fully set up.

When choosing a location for your new aquarium, make sure you place the tank away from open windows. Too much sunlight can cause algal bloom. This in turn decreases the oxygen in the aquarium, which can be very unhealthy for your fish.

Place your new aquarium away from air vents and direct heat. Direct heat will cause the temperature in you aquarium to rise, which can cause diseases in some fish.

Make sure that the aquarium is placed on even ground, since an uneven setting can be very harmful. In addition, check that your floor is strong enough to hold the aquarium. One gallon of water weighs about nine pounds, so a fifty gallon fish tank can weight up to 500 pounds. If your aquarium is a very large one, place it on a sturdy beam. A weak setting can cause your floor to sag, or the aquarium to shatter through the floor.
