Amphipoda
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as '' Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyperiidea
The Hyperiidea are a suborder of amphipods, small aquatic crustaceans. Unlike the other suborders of Amphipoda, hyperiids are exclusively marine and do not occur in fresh water. Hyperiids are distinguished by their large eyes and planktonic habitat. Most species of hyperiids are parasites or predators of salps and jellyfish in the plankton, although '' Themisto gaudichaudii'' and a few relatives are free-swimming predators of copepods and other small planktonic animals. Gallery Taxonomy According to Vinogradov ''et al.'' in 1996, 233 species of Hyperiidea are known. Some controversy exists as to the number of families in the Hyperiidea, being given as between 20 and 23 depending on whether groups like the Thaumatopsidae are considered distinct or not. The taxonomy of Hyperiidea currently accepted by the ''World Register of Marine Species'' is as follows: ;Infraorder Physocephalata Bowman & Gruner, 1973 * Parvorder Physocephalatidira Bowman & Gruner, 1973 ** Superfamily ...

Bougisidae
''Bougisia'' is a genus of plankton in the sub-order Hyperiidea – a type of so-called "hyperid" amphipoda. The genus ''Bougisia'' is the only subordinate taxon in the monotypic family Bougisidae. The genus ''Bougisia'' is also monotypic, being represented by the single species, ''Bougisia ornata''. This species lives as plankton in tropical and sub-tropical salt water. Hyperiidea species normally have a physique that differs from other types of amphipod. Taxonomy The taxonomy of the genus ''Bougisia'' is complicated, has been revised on a number of occasions, and different group affiliation is possible. Prior to 2004, the genera '' Iulopis'' and ''Bougisia'' were part of the family Hyperiidae The Hyperiidae are a family of amphipods, containing these genera: *'' Euthemisto'' Bovallius, 1887 *''Hyperia Hyperia may stand for: * ''Hyperia'' (crustacean), a genus of the order Amphipoda * The ancient Greek name for the island of Amorgos ..., but Zeidler suggested creating tw ...

Plankton
Plankton are the diverse collection of organisms found in water (or air) that are unable to propel themselves against a current (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales. Marine plankton include bacteria, archaea, algae, protozoa and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. Freshwater plankton are similar to marine plankton, but are found in the freshwaters of lakes and rivers. Plankton are usually thought of as inhabiting water, but there are also airborne versions, the aeroplankton, that live part of their lives drifting in the atmosphere. These include plant spores, pollen and wind-scattered seeds, as well as microorganisms swept into the air from terrestrial dust storms and oceanic plankton swept into the air by sea spray.

Order (biology)
Order ( la, 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 directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cystisomatidae
''Cystisoma '' is a genus of amphipod. It is the only member of the family Cystisomatidae within the Hyperiidea. The genus is noted for its nearly completely transparent body, adapted for life in low light waters. Description Gallery ''Cystisoma'' are characterized by unpigmented, transparent bodies which render them essentially invisible in water unless under precisely angled lighting. Only their eyes are pigmented. There is only a single pair of eyes which are large and directed upwards, being spread into a thin sheet on the upper surface of the head. This is likely an adaption of life in the ocean depths, where the only major light source is from above. Marine biologists at Duke University and the Smithsonian analyzed the crustacean's shell and discovered that it was covered in microscopic spheres that significantly reduce reflected light, thus giving the organism an antireflective coating. The spheres are believed to be bacteria due to their morphology and method of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
