In course of evolution, some of these species, like crabs and mollusks, have developed a hard shell (exoskeleton) as a protective covering. As for their world population, it is estimated to be in millions. The Society for Marine Mammalogy, an international scientific society, maintains a list of valid species and subspecies, most recently updated in October 2015. Mollusk — There are over 85,000 different kind of mollusks, and about 23% of the animals in the ocean belong to this animal order. Coming to marine mammals, the list includes whales, like the blue whale, gray whale, and humpback whale, as well as dolphins, seals, sea otters, walruses, sea cows, and polar bears. Anchovy: a small, oily fish of the Atlantic and Pacific, providing food for many fish, marine mammals, and birds. The marine biome is a key component of the Earth’s ecosystem, comprising five oceans―namely the Pacific Ocean, Atlantic Ocean, Indian Ocean, Arctic Ocean, and the Southern Ocean―and several estuaries as well as millions of living organisms that inhabit them.

While the World Registry of Marine Species (WoRMS) has over 200,000 species enlisted in it, the actual number is believed to be at least ten times greater than that. Other than all the animals we have discussed until now, the marine biome also has zooplankton―predominantly comprising small crustaceans and fish larvae―to its credit. You also have the option to opt-out of these cookies. Cephalopods, Crustaceans, & Other Shellfish Corals and Other Invertebrates Even though the open sea is the largest habitat, it is estimated that only five percent of the world's animal species live there. Some species of fish are solitary, while others live in groups known as shoals or schools.

Others live most of their life in the deeper open sea. Marine mammals are aquatic mammals that rely on the ocean and other marine ecosystems for their existence. From sharks and sea turtles to ecosystems and corals, you’re in the right place to take a deep dive into life under the sea. When we talk about marine species, we restrict ourselves to fish, reptiles, mammals, and invertebrates that dwell in oceans and estuaries. These cookies do not store any personal information. Additionally, there are species, like salmons and sea trouts, which frequent between seas and rivers, and deep-sea species, like lanternfish and anglerfish, which are found at depth where even sunlight doesn’t penetrate. Declaration under s248 of the EPBC Act Department of the Environment and Heritage, 14 August 2000 I, Robert Murray Hill, Minister for the Environment and Heritage, in pursuance of s248 of the Environment Protection and Biodiversity Conservation Act 1999, hereby declare that a list of marine species to that Act shall be deemed to be established by inclusion of the following More importantly, there is no questioning the fact that polar bears have a key role to play in the marine ecosystem in polar areas. Zooplankton are important because the energy transfer in the marine food web begins with them feeding on phytoplankton. True, Precambrian organisms existed hundreds of million years ago, but it will be interesting to know about them right? These cookies will be stored in your browser only with your consent.

Odontoceti (toothed whales, except river dolphins) TweetShare78SharePin78 Shares Speaking of endangered ocean species, the earth is now in the midst of its sixth mass extinction of plants and animals — the sixth wave of extinctions in the past half-billion years. One of the most interesting biomes on the planet, the grassland biome is spread across six of the seven continents of the world. It has a huge head and a (comparatively) small, flattened body. EN - endangered Some of the most popular species of seabirds are penguins, albatrosses, gulls, petrels, terns, skuas, auks, gannets, frigatebirds, etc. More Ocean information; Animals of the Oceans: Oceans Animals. As in the case of various terrestrial biomes, invertebrates form a major chunk of living organisms in aquatic biomes. Angelfish: a bright-colored fish of coral reefs.
