The Mysticeti, or baleen whales, have a filter-feeding system, are fifteen species in three families, and include the blue whale, right whales, bowhead whale, humpback whale rorqual, and gray whale. The wide range of body mass in cetaceans has a significant influence on the capacity for oxygen storage and use, which affects dive limits.
Some species of gastropod mollusc, such as the eastern emerald sea slug, are even capable of kleptoplastic photosynthesis via endosymbiosis with ingested yellow-green algae. Almost all aquatic animals reproduce in water, either oviparously or viviparously, and many species routinely migrate between different water bodies during their life cycle.
Over 1500 species of fungi are known from marine environments. [160] These are parasitic on marine algae or animals, or are saprobes feeding on dead organic matter from algae, corals, protozoan cysts, sea grasses, wood and other substrata. [161] Spores of many species have special appendages which facilitate attachment to the substratum. [162]
Marine mammals comprise over 130 living and recently extinct species in three taxonomic orders. The Society for Marine Mammalogy, an international scientific society, maintains a list of valid species and subspecies, most recently updated in October 2015. [1] This list follows the Society's taxonomy regarding and subspecies.
Scientists have identified several new marine species in a pristine underwater ecosystem recently discovered in international waters -- and they expect to find more. Modern technology that allows ...
Aquatic insects live mostly in freshwater habitats, and there are very few marine insect species. [9] The only true examples of pelagic insects are the sea skaters , which belongs to the order Hemiptera, and there are a few types of insects that live in the intertidal zone , including larvae of caddisflies from the family Chathamiidae , [ 10 ...
The new species of snailfish has a red body and pink lips, with a humpback shape from the side, researchers said. Discover more new species Thousands of new species are found each year.
Sound from an underwater source can propagate relatively freely through body tissues where there is contact with the water as the acoustic properties are similar. When the head is exposed to the water, a significant part of sound reaches the cochlea independently of the middle ear and eardrum, but some is transmitted by the middle ear.
