Description

Prodajus ostendensis grows to a length of about 3 mm (0.1 in). The female has a symmetrical leaf-shaped body with the mouth on the underside and a two-lobed brood pouch enclosed by small oostegites. The segmentation is indistinct and the five pairs of pereiopods (thoracic limbs) are small and close to the mouth. The pleopods (abdominal legs) are either small or missing altogether. The male often has its segments fused together and has a relatively long pleon (abdomen).[4]
