Adyte assimilis
''Adyte assimilis'' is a marine polychaete scale worm in the family Polynoidae.
==Description==
''A. assimilis'' is colourless or yellowish, up to thirty millimetres long, and has a dark band running down its back. It has fifteen pairs of scales or elytrae which cover the length of the body. These are delicate, transparent and rounded and do not meet at the back.〔John Barrett and C M Young, Collins Pocket Guide to the Sea Shore (1958) p.68〕 The body is of uniform width with smooth dorsal and ventral surfaces. The prostomium has a median antenna and a pair of lateral antennae. There are a pair of palps and two pairs of eyes, the anterior pair on the line of greatest width, the posterior pair near the rear margin. The first segment bears chaetae and a pair of dorsal and ventral tentacular cirri.〔(Marine species identification portal )〕 There is a long posterior region without scales. The notosetae are at least as thick as the neurosetae, being smooth with few spines. The neurosetae have semilunar pockets, faintly bifid tips and faint serrations. The presetal neuropodial lobes are longer than the postsetal ones.〔(The polychaete worms: definitions and keys to the orders, families and genera. )〕
