Bathynomus vaderi can be up to 12.8 inches (0.325 m) in length and 2.2 pounds (0.997 kg) in weight, [4] and is one of the largest known species of isopods. [5] The species is predicted to have a similar habitat to the other giant isopod species Bathynomus jamesi .
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.
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]
Young isopod crustaceans hatch directly into a manca stage, which is similar in appearance to the adult. The lack of a free-swimming larval form has led to high rates of endemism in isopods, but has also allowed them to colonise the land, in the form of the woodlice.
[3] [4] This is large for an isopod, most of which are between 0.5 and 1.5 cm (0.2–0.6 in) in length. [5] 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. [6]
