Neomysis integer
''Neomysis integer'' is a species of opossum shrimp found in shallow marine bays and estuaries of Europe, with a transparent greenish or brownish body and a large cephalothorax. It is found in very shallow water in both high and low-salinity habitats. It is a filter feeder and the female broods her eggs in a brood pouch beneath her cephalothorax.
==Description==
''Neomysis integer'' is a slender opossum shrimp growing to a maximum length of about . The head has a pair of large, stalked eyes and two pairs of antennae, both of which are biramous (branched into two parts). The exopod (the outermost branch) of the second antenna forms an elongated scale with bristles round its edges and extends forward into a sharp point. The thorax has eight segments each bearing a pair of biramous limbs, the outer branches of which have a feathery appearance. The head and first six segments of the thorax are covered by a protective carapace which extends forward in a triangular plate with a depressed centre between the eyes. The abdomen bears short limbs and the last segment bears larger, flattened biramous limbs which form a tail fan. The telson (the last abdominal segment between the tail fan) is not forked, a fact emphasised by the specific name ''"integer"''. This opossum shrimp is semi-transparent, sometimes with a brownish tinge.〔(【引用サイトリンク】title=An opossum shrimp - ''Neomysis integer'' )〕〔
