A suborder of the Isopods. These crustaceans are characterized by slender, elongate, subcylindrical bodies, and by the fact that the outer branch of the paired tail appendage (uropod) arches over the base of the terminal abdominal segment, the telson (see illustration). The uropods of anthurideans attach laterally to the abdomen and together with the telson form a caudal fan.
Paranthura infundibulata.
Marked sexual dimorphism is shown in the first pair of antennae which, in males of many species in both sections, develop brushlike whorls of setae on the flagellum. Female anthurideans carry the developing young beneath the thorax in a brood pouch, formed by overlapping plates originating from the bases of several pairs of legs. See also Sexual dimorphism.
Anthurideans are mostly marine, but some live in brackish or freshwater habitats. Some are facultative ectoparasites of fishes. See also Isopoda.
