They are ubiquitous in marine, freshwater and terrestrial environments, where they often outnumber other animals in both individual and species counts. They are found in every part of the Earth's lithosphere, from the top of mountains to the bottom of oceanic trenches. [261] By count they represent 90% of all animals on the ocean floor. [262]

A whole new world: Surprising ecosystem thriving under sea floor. The study authors found the tubeworms and other species living in warm, fluid-filled cavities more than 2,500 meters, or 1.5 miles ...
Ctenophores are found in most marine environments: from polar waters at −2 °C to the tropics at 30 °C; near coasts and in mid-ocean; from the surface waters to the ocean depths at more than 7000 meters. [75]
There are 3,000-plus types of nudibranchs in the ocean. The nudibranch is a carnivorous mollusk that can appear strikingly beautiful or drab. There are 3,000-plus types of nudibranchs in the ocean.
The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates ...
Scientists believe they’ve discovered an ancient ocean floor comprising a new layer between Earth’s mantle and core.
