General Description

Body cylindrical, with prominent antennae. The first four pairs of legs are thin and with rows of hairs; the last three pairs are more stubby and attach the animal. The body bends between the elongate fourth body segment and the fifth, up to 10 mm long.

Biology

Neastacilla species are the masters of disguise as both the colour and slender body of these isopods would fool even the hungriest of predators into looking elsewhere for its meal.
