Which Animals Live on the Sea Floor?

Animals that inhabit the deep ocean. There is no strict distinction with shallow-water animals, and they usually refer to animals that inhabit the depths of the continental shelf to the depth of 200 meters below the ocean, that is, deep-water and deep-sea bottom animals. There are also rare animals that are produced deeper on the continental shelf and are called deep-sea animals. There are many deep-sea animals whose larvae live near the surface of the sea and then move vertically on a large scale; therefore, deep-sea animals are not so much animals that live in the depths of the ocean. The body color of deep-sea animals is generally gray or even black, and occasionally bright red. Fish and crustaceans have eyes with or without eyes, but also have light-emitting organs. Especially deep fish, many of them have poorly developed side muscles and insufficient ossification. The size is huge, the appendages are growing, the protrusions are developed, and so on. These are the characteristics of deep-sea animals. It is still doubtful that these are special adaptations to deep-sea life. There are very few primitive animals in the ocean floor and trenches. Many of them are species that originated from the continental shelf slopes and were once called the old deep ocean floor. In addition, the common species (extensive species) of deep-sea benthic animals mostly belong to the old deep-sea bottom zone. Scoto-planes globosa (sea rat), Parapagurus pilosim-anus (heterotail), etc. are examples in this regard. In addition, there are a wide range of species such as Amphicteis gunneri (hairy species), Echinocardiumaustrale (sea urchins), and Siboglinum caulleryi (whiskers) that extend from the subtidal zone to the ocean floor and even trenches.

Deep sea animal

Deep sea animals are those that inhabit the deep sea.

As a zoogeographic area on the ocean floor, S. Ek-man (1953) once divided it into four regions: the Atlantic Ocean, the Indian Ocean-Pan-Pacific Ocean, the Arctic, and the Antarctic; -

(1959) merged the Arctic Ocean into the Atlantic Ocean and divided it into three regions; FJ Madsen (1953, 1961) advocated that the Indian Ocean and the South Ocean Islands should also be merged into the Atlantic Ocean, and divided into the Atlantic-Indian Ocean, Pacific Ocean, and Antarctic Three areas, and correspondingly designated as coccidiosis soft mud area, brown clay area, diatom soft mud area
