Anterior pair of eyes dorsolateral at widest part of prostomium, posterior pair dorsal near hind margin. Parapodia with elongate acicular lobes with both acicula penetrating epidermis; neuropodia with a supra-acicular process. Notochaetae stout with distinct rows of spines and blunt tip. Neurochaetae more numerous and more slender, with distinct rows of spines distally and exclusively unidentate tips. The genus was described in 1865, ...

Eunoe Leiotentaculata
''Eunoe leiotentaculata'' is a scale worm known from southern Australia and New Zealand and the South Pacific Ocean at depths of 500-1200 m. Species recognition Within the geographic range of ''Eunoe leiotentaculata'', at least 100 other species of Polynoidae also occur, but only about 3 other species share these features: 41-55 segments, a pair of distinct “peaks” on the prostomium, 15 pairs of elytra which have smooth margins lacking papillae, and all the ventral chaetae taper to a simple point. The taxonomic description below, and original sources, will be required to distinguish ''Eunoe leiotentaculata'' from the most similar species. Distribution This species was originally collected in 1976 on a Russian voyage through the Tasman Sea and is now known to occur at depths of 500–1300 m around the coast of southern Australia and New Zealand. Description ''Eunoe leiotentaculata'' is a short-bodied worm with 45–55 segments and 15 pairs of elytra, which are c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
