Amphipoda (/ æmˈfɪpədə /) is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods (/ ˈæmfɪpɒdz /) range in size from 1 to 340 millimetres (0.039 to 13 in) and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described.
Taxonomy of diatoms. Light microscopy of several species of living freshwater diatoms. Diatoms belong to a large group called the heterokonts, which include both autotrophs such as golden algae and kelp; and heterotrophs such as water moulds. The classification of heterokonts is still unsettled: they may be designated a division, phylum ...
Phylogenetic relationships of the Gobiiformes have been elucidated using molecular data. [3] [4] Gobiiforms are primarily small species that live in marine water, but roughly 10% of these species inhabit fresh water. This order is composed chiefly of benthic or burrowing species; like many other benthic fishes, most gobiiforms do not have a gas ...
Acropora is a genus of small polyp stony coral in the phylum Cnidaria. [3] Some of its species are known as table coral, elkhorn coral, and staghorn coral. Over 149 species are described. [4] Acropora species are some of the major reef corals responsible for building the immense calcium carbonate substructure that supports the thin living skin ...
Marine invertebrates are animals that inhabit a marine environment apart from the vertebrate members of the chordate phylum; invertebrates lack a vertebral column. Some have evolved a shell or a hard exoskeleton. The earliest animals may belong to the genus Dickinsonia, [2] 571 million to 539 million years ago. [3]

Order (Latin: ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added ...
Anthozoa is a subphylum of marine invertebrates which includes sessile cnidarians such as the sea anemones, stony corals, soft corals and sea pens. Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as planktons. The basic unit of the adult is the polyp; this consists of a cylindrical column topped by a disc ...
