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; the specific name sicula means "of Sicily". It is deposited at the Muséum d'Histoire Naturelle (Musée Barla) in Nice.
