Asellota
Asellota is a suborder of isopod crustaceans found in marine and freshwater environments. Roughly one-quarter of all marine isopods belong to this suborder. Members of this suborder are readily distinguished from other isopods by their complex copulatory apparatus. Other characteristics include six-jointed antennal peduncle, the styliform uropods (a character shared with some other isopod groups), the fusion of pleonites 5, 4 and sometimes 3 to the pleotelson, and absence of the first pleopod in females. Classification The suborder Asellota comprises these families: Some classifications also include the Microcerberidea within Asellota.

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 ...

Asellus Aquaticus
''Asellus aquaticus'' is a fresh water, freshwater crustacean resembling a woodlouse. It is known by various common names including pond slater, water louse, aquatic sowbug, water hoglouse and cress bug. Ecology ''Asellus aquaticus'' is common throughout the temperate zone, including Europe and Russia. It is found in rivers, streams and standing water, particularly where there are plenty of stones under which it hides, but it is not found where the water is strongly acidic. It is a detritivore. ''Asellus aquaticus'' is relatively tolerant of a range of pollutants and has been used as an indicator of water quality. Life cycle and reproduction ''Asellus aquaticus'' can breed throughout the year, if the temperature is high enough: they do not breed under cold temperatures. Maturity can be reached in few months under warm summer temperatures, but maturation may take as much as two years in permanently cold water bodies (e.g., high-latitude or mountain waters). Life span varies simil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
