Valvifera
The Valvifera are marine isopod crustaceans. Valviferans are distinguished, however, by the flat, valve-like uropods which hinge laterally and fold inward beneath the rear part of their bodies, covering the pleopods. Some species are omnivorous, and serve as effective scavenger Scavengers are animals that consume Corpse decomposition, dead organisms that have died from causes other than predation or have been killed by other predators. While scavenging generally refers to carnivores feeding on carrion, it is also a he ...s in the economy of the sea.

Glyptonotus Antarcticus
''Glyptonotus antarcticus'' is a benthic marine isopod crustacean in the suborder Valvifera. This relatively large isopod is found in the Southern Ocean around Antarctica. It was first described by James Eights in 1852 and the type locality is the South Shetland Islands. Description ''Glyptonotus antarcticus'' has a typical maximum length of , but may rarely reach up to . This is large for an isopod, most of which are between in length. It has two pairs of compound eyes, a large pair on the dorsal surface and a smaller pair on the ventral surface. Glyptonotus antarcticus has only five ommatidia, which is unusual for crustaceans and insects. It is thought that the latter are useful when the animal is swimming, which it does in an upside-down position. With the exception of the eyes, certain mouthparts and feet, the whole surface of the animal has minute cuticular outgrowths of feathery hairs and knobbly scales. It is thought that these may help to prevent attachment of Forami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arcturidae
The Arcturidae are a family of marine isopod crustaceans in the suborder Valvifera. Members of the family resemble woodlice and are found globally in cooler areas in shallow seas. Description The head is incapable of rotating laterally. Two pairs of antennae are set at the front of the head. The eyes are usually well developed and the mouthparts do not form a suctorial cone or proboscis. The thorax or pereon is smooth or slightly sculptured and sometimes spinose or rugose. A flexion occurs between it and the abdomen or pleon, so from a lateral view, the front part of the animal is arched up. The pereiopods are held close to the head, while the pleopods are attached to the pleon, making it appear no appendages on the pereon. Genera The World Register of Marine Species includes these genera in the family: *'' Agularcturus'' Kensley, 1984 *'' Amesopous'' Stebbing, 1905 *''Arctopsis'' Barnard, 1920 *'' Arcturina'' Koehler, 1911 *'' Arcturinella'' Poisson & Maury, 1931 *'' Arcturinoi ...

Isopoda
Isopoda is an order of crustaceans. Members of this group are called isopods and include both aquatic species and terrestrial species such as woodlice. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration. Females brood their young in a pouch under their thorax called the marsupium. Isopods have various feeding methods: some eat dead or decaying plant and animal matter, others are grazers or filter feeders, a few are predators, and some are internal or external parasites, mostly of fish. Aquatic species mostly live on the seabed or the bottom of freshwater bodies of water, but some taxa can swim for short distance. Terrestrial forms move around by crawling and tend to be found in cool, moist places. Some species are able to roll themselves into a ball as a defense mechanism or to conserve moisture like species in the family Armadilli ...

Scavenger
Scavengers are animals that consume Corpse decomposition, dead organisms that have died from causes other than predation or have been killed by other predators. While scavenging generally refers to carnivores feeding on carrion, it is also a herbivorous feeding behavior. Scavengers play an important role in the ecosystem by consuming dead animal and plant material. Decomposer, ''Decomposers'' and detritivores complete this process, by consuming the remains left by scavengers. Scavengers aid in overcoming fluctuations of food resources in the environment. The process and rate of scavenging is affected by both Biotic component, biotic and Abiotic component, abiotic factors, such as carcass size, habitat, temperature, and seasons. Etymology Scavenger is an alteration of ''scavager,'' from Middle English ''skawager'' meaning "customs collector", from ''skawage'' meaning "customs", from Old North French ''escauwage'' meaning "inspection", from ''schauwer'' meaning "to inspect", of ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...
