What are the varieties of marine life found in the Antarctic waters?
==== ‍‍What special adaptations have these marine creatures made to survive in such extreme conditions? ==== ==== ‍What adaptation have fish made that allow them to survive in the freezing waters without freezing themselves? ====

THEMSELVES?
Mostly all sea animals in Antarctica has anti-freeze in them so they can survive in the extremly cold water. You might be thinking what is anti-freeze well its a ice crystal inside the animals body, this can allow them to survive in the freezing cold water.

WHAT ARE THE VARIETIES OF MARINE LIFE FOUND IN THE ANTARCTIC WATERS?
The varieties of marine life in the Antarctic waters are krills, fish and phyteplankton. There are only 120 species in the antarctic waters and four families : Antarctic cod, plunder fish, dragonfish and icefish. The most unusual fish is the icefish. There are also squid, giant sea spiders, jellyfish, sea ergents and starfish.

Antarctic Ice Fish

Ice fish is an unusual fish known in Antarctica. They have no heamoglobin in their body and only 10% of normal oxygen.The ice fish can only stand low water tempretures because only 10% of normal oxygen stored. The Ice fish is only found in Antarctica because in other places don't have such extreme cold waters. They can be found in the southern oceans of Antarctica and around Antartica because it's more colder in those places. There are 16 species of ice fish in Antarctica and mostly all feed on krills, fish, crad and phytoplankton. They have no major predetors.

Krills

You might be thinking what are krills well they're small creatures shrimp-like. krill are the top of the food chain,mostly all marine animals feed on them. They have five pairs of legs and several more legs to catch food like copepods. Krills in Antarctca feed on phytoplankton, copepods, zooplankton and algae. Krills live under and around Antarctica.

Antarctic cod The Antarctic Cod is also called the Antarctic toothfish. Antarctic cod is found in the southern oceans and around Antarctica in the open ocean.The Antarctic cod mainly eats fishes, the Antarctic silverfish, spuid and crustaceans. The werd thing is that the Weddell seals often hunt for the Antarctic cod. They have this antifreeze blood bone to prevent them frpm freezing. The Antarctic cod dose not have any predators because it eats almost everything even the remainings of penguins after been eaten by seals.



Phytoplankton

Phytoplankton is a growing plant that feeds almost all water creatures in Antarctica. There are lots of kinds and types of phytoplanktons in Antarctica like casey. Did you ever know that the phytoplankton used to be at the North pole and not the south, but the North pole started to melt so the phytoplankton wasen't able to grow so now they are mainly in the south pole. They have no predators because they are swimming plants.

Hoff crab

The Hoff crab is a **hairy chested** crab with antifreeze. It lives under, around Antarctica and also it lives in warm places. The Hoff crab grows a **farm of bacteria** as it main food source in it's hairy chest and it's hair.

WHAT DO THE FISH EAT TO SURVIVE?
Most fish in the Antarctic waters eat krills and the little fish eat phytoplankton. The fish and animals in the Antarctic waters alsoeat each other but it's mainlythe big eating the small.
