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.
The database can be searched using name (genus or species) or using a part of the CO1 DNA sequence. Aquagene. A collaborative product developed by several German institutions, Aquagene provides free access to curated genetic information of marine fish species. The database allows species identification by DNA sequence comparisons.
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]
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 ...
Total species range is highly variable for marine mammal species. On average most marine mammals have ranges which are equivalent or smaller than one-fifth of the Indian Ocean . [ 33 ] The variation observed in range size is a result of the different ecological requirements of each species and their ability to cope with a broad range of ...
For example, certain Desis species spend the high tide in an air-filled underwater retreat made from silk and forage on land in the intertidal zone during low tide. [ 10 ] [ 14 ] [ 15 ] Some spiders living in periodically flooded habitats can survive for an extended period underwater by entering a coma-like state, up to 16–36 hours in Arctosa ...
A survey published in 2004, [3] studies why automated species identification had not become widely employed at this time and whether it would be a realistic option for the future. The authors found that "a small but growing number of studies sought to develop automated species identification systems based on morphological characters".
