Systematics, biology and biogeography of the Cranchiid cephalopod genus Teuthowenia (Oegopsida)
Teuthowenia is comprised of three discrete, closely related, allopatric species. Synonymies, definitions, diagnoses and keys to all developmental stages are presented, along with a review of the complex history of the genus and detailed illustrations. The discrete, ecologically distinct, distributio...
