词汇：ocean creatures 海洋生物
The ocean covers over 70% of the surface of our planet, though, according to the National Ocean Service, 95% of it remains unexplored. This is because under the surface is a dark and hostileenvironment with unrelentinghigh pressure, freezingtemperatures and bizarrecreatures in the depths.
The Census of Marine Life reports more than 17,000 speciesliving in the deep sea. The Greenland shark can live in depths of 7,200 feet and is a rarely seen Arcticpredatorsaid to live to 400 years old and reach 23 feet in length. In order to battle the icy depths, Greenland sharkshave chemicals in their skin which prevent icecrystalsfrom forming on their body.
Another deep-sea creature is the giant squid, an animal that remains a mystery to scientists despite being the largest invertebrateon Earth. Living far below the surface, what we know has largely come from carcassesbeing washed ashore. Marine biologistshave found that they feed on fish, squid and possibly even small whales. They find preyusing eyes which are ten inches wide, roughly the size of a dinner plate!
Other unusual creatures include the vampire squid, which lives 2000 to 3000 feet under the ocean and is so-called because of its dark cloak that connects its eight arms. There is also the dumbo octopus, named due to its resemblance to the elephant from the 1943 Disney film Dumbo, with its protrudingears. Another unique creature is the anglerfishknown for the light that hangs from its head.
So, enjoy swimming, but don’t venturetoo far down – you never know what is lurkingbeneath!
