Hyperiidea
The Hyperiidea is one ot the six suborders of amphipods, small aquatic crustaceans. Unlike some 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 World Amphipoda Database, 284 species of Hyperiidea are known in 2025. 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 ...

Phronima Sedentaria
''Phronima sedentaria'' is a species of amphipoda, amphipod crustaceans found in oceans at a depth of up to . They are large in size relative to other members of the family Phronimidae. Individuals may be found inside barrel-like homes, created most commonly from the tunics of select species of Thaliacea, pelagic tunicates; ''Phronima'' females appropriate these tunics and rear their young within. ''P. sedentaria'' is known to employ multiple feeding strategies and other interesting behaviors, including daily vertical migration. The species is also known by the more common names pram bug and barrel shrimp. Description ''Phronima sedentaria'' is the largest and most abundant species in the family Phronimidae. Sexual dimorphism is reflected between male and female members in the more extended and prominent antenna (biology), antennae of the males relative to the short, reduced ones of females. More obviously, the size discrepancy between males and females distinguishes them further. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphipod
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 10,700 amphipod species currently recognized. They are mostly marine animals, but are found in almost all aquatic environments. Some 2,250 species live in fresh water, and the order also includes the terrestrial sandhoppers such as '' Talitrus saltator'' and '' Arcitalitrus sylvaticus''. Etymology and names The name ''Amphipoda'' comes, via Neo-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 ...

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 r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Plankton are the diverse collection of organisms that drift in Hydrosphere, water (or atmosphere, air) but are unable to actively propel themselves against ocean current, currents (or wind). The individual organisms constituting plankton are ca ... 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, but Zeidler suggested creating ...
