Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are a part of the subphylum Crustacea (/ k r ə ˈ s t eɪ ʃ ə /), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp, branchiopods, fish lice, krill, remipedes, isopods ...
The diagram illustrates the material fluxes, populations, and molecular pools that are impacted by five cryptic interactions: mixotrophy, ontogenetic and species differences, microbial cross‐feeding, auxotrophy and cellular carbon partitioning. These interactions may have synergistic effects as the regions of the food web that they impact ...
Copepods (/ ˈ k oʊ p ə p ɒ d /; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat.Some species are planktonic (living in the water column), some are benthic (living on the sediments), several species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as ...
Aquaculture (less commonly spelled aquiculture [1]), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus).

Within cartilaginous fish, approximately 80% of the sharks, rays, and skates families survived the extinction event, [114] and more than 90% of teleost fish (bony fish) families survived. [115] There is evidence of a mass kill of bony fishes at a fossil site immediately above the K–T boundary layer on Seymour Island near Antarctica ...
A vampire hedgehog, a pygmy pipehorse and a "blob-headed" fish were among the hundreds of new species identified in 2024. The variety of species identified was quite eclectic and names for the new ...
Some 33,000 species (only 13,000 of which are extant) have been identified, [2] grouped into 7 valid orders. [2] They are small crustaceans, typically around 1 mm (0.04 in) in size, but varying from 0.2 to 30 mm (0.008 to 1 in) in the case of the marine Gigantocypris .
