I like the post that Carson made about creatures that live beneath the Challenger Deep area – the deepest known point in the Earth's seabed. I am most interested about the animals that I have never heard before such as the Frilled Shark, Atlantic Wolf Fish Pair and the Six Gilled Shark. I like the part where Carson mentioned the Giant Spider Crab because I have seen a BBC documentary before and I saw that it fed on the carcass of a dead Sperm whale. It was also interesting that the crab can live up to 100 years old. I never knew that before.
I like going back to Carson’s post because it has interesting facts about deep sea creatures like the giant Japanese Spider crab which is 3.7 meters long. I am wondering how much they weigh or whether they can be eaten and how to cook them in a pot. I also wonder what the tube worms eat since he did not mention it in his blog.
Due to my interest, I also did some research about animals that live in the deep. I learned that different kind of sharks can dive only at certain depths in the ocean. There are sharks that can live only within the sunlit areas or Euphotic zones. This zone is up to 660 feet deep. Some examples of sharks that live in the Euphotic zones are Gray Nurse shark, Bull shark, Great Hammerhead shark, Whale shark, Galapagos shark and Salmon shark.
Another group of sharks can dive up to the Twilight or Disphotic Zone. This zone is from 660 down to 3,300 ft. Some examples of shark that can dive up to this zone are the Tiger shark, Blue shark, Great White shark, Goblin shark, Greenland shark and the Pacific Sleeper shark.
The deepest zone that a shark can dive is the Midnight or the Aphotic zone. This is the depth lower than 3,300 feet. Some examples of shark that can dive up to this level are the Filled shark that can dive up to a depth of 4,200 feet. The only known shark that can dive up to maximum depths of 12,100 feet is the Portuguese Dogfish shark. I wonder how it can overcome the very high pressure down there.
