Odell Down Under was released alongside a re-release of its companion game, Odell Lake. [2] The game was recommended for ages 9 to adult. [3]The game was generally praised; School Library Journal cited the "realistic and beautiful" graphics and detailed field guide as strengths, [4] while Booklist called it a "marvelous introduction to life in a thriving underwater community."
The proper identification of fish specimens with DNA barcoding methods relies heavily on the quality and species coverage of available sequence databases. A fish reference database is an electronic database that typically contains DNA barcodes, images, and geospatial coordinates of examined fish specimens.
Today, marine species range in size from the microscopic phytoplankton, which can be as small as 0.02–micrometres; to huge cetaceans like the blue whale, which can reach 33 m (108 ft) in length. [5] [6] Marine microorganisms have been variously estimated as constituting about 70% [7] or about 90% [8] [1] of the total marine biomass.
This is a list of various species of marine invertebrates, animals without a backbone, that are commonly found in aquariums kept by hobby aquarists. Some species are intentionally collected for their desirable aesthetic characteristics. Others are kept to serve a functional role such as consuming algae in the aquarium.
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 ...
The original benthograph built by USC was very successful in taking a series of underwater photos until it became wedged between some rocks and could not be retrieved. [30] Remote operated vehicles (ROVs) are also seeing increasing use in underwater exploration. These submersibles are piloted through a cable which connects to the surface ship ...
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.
Although there are freshwater species, the great majority are marine (salt water) species, ranging from tidal zones to depths exceeding 8,800 m (5.5 mi). While most of the approximately 5,000–10,000 known species feed on bacteria and other food particles in the water, some host photosynthesizing micro-organisms as endosymbionts and these ...
