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.
It is a member of the giant isopods (Bathynomus), and as such it is related—albeit distantly—to shrimps and crabs. [2] It was the first Bathynomus species ever documented and was described in 1879 by French zoologist Alphonse Milne Edwards after the isopod was found in fishermen's nets off the coast of the Dry Tortugas in the Gulf of Mexico .
Giant isopods have been recorded in the West Atlantic from the US state of Georgia to Brazil, including the Gulf of Mexico and the Caribbean. [1] The four known Atlantic species are B. obtusus, B. miyarei, B. maxeyorum, and B. giganteus, and the last of these is the only species recorded off the United States.
As an example, T+ albino isopods are the result of an isopod being born without the ability to produce melanin, removing all black pigmentation. However, they are believed to be tyrosinase-positive (hence the T+), and therefore can still create some darker pigments such as brown and purple. T− albino isopods are thought to lack both melanin ...
Armadillidiidae is a family of woodlice, a terrestrial crustacean group in the order Isopoda.Unlike members of some other woodlice families, members of this family can roll into a ball, an ability they share with the outwardly similar but unrelated pill millipedes and other animals.
Armadillidium vulgare, the common pill-bug, potato bug, common pill woodlouse, roly-poly, slater, doodle bug, or carpenter, is a widespread European species of woodlouse.It is the most extensively investigated terrestrial isopod species. [2]
This artificial habitat was constructed near the isopod's native habitat. It attempts to best replicate its natural environmental conditions. It consists of 8 artificial pools connected by pipes. Controlled propagation of isopods began at the facility in 1990. 600 isopods were introduced to the facility, with 75 isopods per pool. [10]
Hemilepistus reaumuri is a species of woodlouse or isopod that lives in and around the deserts of North Africa and the Middle East, "the driest habitat conquered by any species of crustacean, not including insects which are now known to be crustaceans pancrustacea". [3]
