The evolution of coleoid cephalopods and their present biodiversity and ecology
The present status of phylogeny and classification in coleoid cephalopods and the effect of evolution on the present ecology and biodiversity in the group are examined. The basis of knowledge ofExpand

Artificial fertilization and development through hatching in the oceanic squids Ommastrephes bartramii and Sthenoteuthis oualaniensis (Cephalopoda: Ommastrephidae)
A technique for routinely obtaining hatchlings of oceanic squids via artificial fertilization is not available at present. This paper makes a major advance in that direction. A technique forExpand

‘Lophenteropneust’ hypothesis refuted by collection and photos of new deep-sea hemichordates
The deep ocean is home to a group of broad-collared hemichordates—the so-called ‘lophenteropneusts’—that have been photographed gliding on the sea floor but have not previously been collected. It hasExpand

A molecular phylogeny of the Octopoda (Mollusca: Cephalopoda) evaluated in light of morphological evidence.
In this paper we examine the phylogenetic relationships of the Octopoda utilizing molecular sequence data from the cytochrome c oxidase subunit I (COI) gene and compare results from analyses ofExpand

The ink sac clouds octopod evolutionary history
Difficulties in elucidating the evolutionary history of the octopods have arisen from problems in identifying informative morphological characters. Recent classifications have divided the largestExpand

In Situ Observations on Three Species of Large-Finned Deep-Sea Squids
The manned submersible JOHNSON SEA-LINK II was used for a series of dives on the continental slope of the eastern Gulf of Mexico in September 1995. The deep-sea squids Mastigoteuthis hjorti Chun,Expand

Distribution, relative abundance, and developmental morphology of paralarval cephalopods in the western North Atlantic Ocean
Paralarval and juvenile cephalopods collected in plankton samples on 21 western North Atlantic cruises were identified and enumerated. The 3731 specimens were assigned to 44 generic and specificExpand

Evolution of the cephalopod head complex by assembly of multiple molluscan body parts: Evidence from Nautilus embryonic development
Cephalopod head parts are among the most complex occurring in all invertebrates. Hypotheses for the evolutionary process require a drastic body‐plan transition in relation to the life‐style changesExpand
