Teuthoids occur in the Lower and Middle Turonian boundary interval in the Bohemian Cretaceous Basin (BCB). Five genera (three of them new-Paraglyphiteuthisn.g., Marekitesn.g. and Eoteuthoidesn.g.)i and sixand/or seven speciesare described on the basis

On the basis of a uniquely preserved gladius of the Turonian coleoid cephalopod, the new genus Eoteuthoides Kostak, 2002, and the new fam-ily Eoteuthoidae fam. nov. are established. Designation of a new higher taxomomic unit is based on marked morphological

A reproductive strategy consisting of deep- water spawning and egg-care was inferred for the midwater squid Gonatus onyx Young, 1972. Brooding females and associated eggs and hatchlings, captured between 1250 and 1750 m depth off southern California,

Some deep water squids are known to achieve neutral buoyancy by storing ammonium in their body tissues. The Cranchiidae use a unique coelomic cavity to store ammoniacal fluid; in 15 other families, ammonium appears to be sequestered in either vacuoles
