''Chtenopteryx sicula'', also known as the comb-finned squid or toothed-fin squid, is a species of squid native to at least the Mediterranean Sea. It is characterised by several distinct morphological features: ocular photophores are present but visceral photophores are absent, arm suckers are arranged in at least 4 series distally, and club suckers are borne in more than 8 series. The type specimen was collected off Messina, Italy. It is deposited at the Muséum d'Histoire Naturelle (Musée Barla) in Nice.〔(Current Classification of Recent Cephalopoda )〕 Image:Chtenopteryx sicula2 - from Commons.jpg|Ventral view of the viscera, showing the absence of a visceral photophore and the presence of the accessory nidamental gland. ==References== 〔 *Naef, A. 1921-23.
