Sea pig

Sea pigs are found in all over world’s oceans. In some areas, they comprise more than 95% of the total weight of animals on the deep-sea floor. Despite their huge numbers, most people will never see a sea pig, as they live in the coldest and deepest parts of the ocean. Sea pigs tend to be about 4-6 inches long. They were first described by Swedish zoologist Hjalmar Théel in 1882. Théel described about 65 new species discovered by the British research ship HMS Challenger during her round-the-world expedition of 1872 through 1876. Sea pigs have five to seven pairs of enlarged tube feet. These “walking legs” are hydraulically operated appendages that can be inflated and deflated to move around. sea pigs are deposit or detrital feeders, eating bits of decaying plant and animal material found in deep sea mud. Their mouths are surrounded by a ring of feeding tentacles that they use to sift through the mud and grab onto food. Sea pigs are especially fond of food that has recently fallen from the ocean’s surface, like a whale corpse.

It can be found off the coasts of mainland Australia, Tasmania and New Zealand. Unlike what most people think they look like blob fish look completely different under the water than above because they don’t have any muscles so once they get above land their body basically deflates. In a single given nest a female blobfish can lay thousands of eggs at once. It is unknown just how long a blobfish lives for from the time it is born until it dies. If a blobfish is left out of the water for too long, their skin will dry out and they will die. Unlike other fish, blobfish do not have swim bladders to help them float in the water at various levels. On average, blobfish will be around ten inches to a foot long. Blobfish are currently listed as an endangered species of
