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.
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.
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. [2]
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 ...
The Cymothoidae are a family of isopods in the suborder Cymothoida found in both marine and freshwater environments. Cymoithoids are ectoparasites, usually of fish, and they include the bizarre "tongue-biter" (Cymothoa exigua), which attaches to a fish's tongue, causing it to atrophy, and replaces the tongue with its own body.

The Asellidae are a family of isopod crustaceans, [1] one of the largest families of freshwater isopods, living in both epigean and hypogean habitats in North America and Europe. [ 3 ] Genera
The largest specimen in the study weighed more than 1 kilogram (2.2 pounds) and measured 32.5 centimeters long (12.8 inches), making B. vaderi one of the world’s largest known isopods.
This is an artificial habitat constructed outside the isopod's native habitat in order to best replicate its natural environmental conditions. Controlled propagation of isopods began at the facility in 1990. Further captive populations are present in the ABP, New Mexico Tech, and the New Mexico Department of Game and Fish laboratory. [3]
