Baited remote underwater video (BRUV) is a system used in marine biology research. By attracting fish into the field of view of a remotely controlled camera, the technique records fish diversity , abundance and behaviour of species.
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 ...
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]
Currently, of the approximately 12,000 extant reptile species and sub-species, only about 100 of are classed as marine reptiles. [30] Except for some sea snakes, most extant marine reptiles are oviparous and need to return to land to lay their eggs. Apart from sea turtles, the species usually spend most of their lives on or near land rather ...
The new species marks the first time that the Nidirana genus has been found in India, scientists said. Nidirana species are known in Japan, Taiwan, China, Vietnam, Laos and Thailand.
As at July 2018, the OBIS website states that the system provides access to over 45 million observations of nearly 120,000 marine species (the reduced number of names cited being as a result of synonym resolution, i.e. reduction of taxa recorded under multiple names to a single accepted name), based on contributions from 500 institutions from ...
Numerous species, including some Ancylometes, Dolomedes, Megadolomedes, Pardosa, Pirata, Thalassius and others, live above water at the surface, but may actively submerge for a prolonged period, are strong swimmers and will catch underwater prey. [9] [10] [17] Several of these, as well as a few others, may dive into the water to avoid larger ...
