Some Pacific Cephalopods

Species Composition and Distribution of Pelagic Cephalopods from the Pacific Ocean off Oregon

MUCH OF OUR PRESENT KNOWLEDGE about the species composition and distribution of ceph alopods of the Pacific Ocean is derived from collections made on cruises of the "Albatross," steamer of the U.S. Fish Comm ission, dur ing the late nine teenth and early twentieth centuries. "Albatross" collections along the west coast of North America were taken mainly off California and Central America or Ala...

Spiders from some Pacific Islands

KNOWLEDGE OF THE SPIDERS of the Pacific is largely the result of the work of Berland (1934, et. seqq.). He has published a number of papers dealing with the spiders of the New Caledonian and New Hebridean region; of Samoa; and of the Marquesas, Society, and Austral groups, and other islands in the southeastern Pacific. Recently I have completed a study of the spiders of Western Samoa (not yet p...

Phospholipids in Mediterranean cephalopods.

Polar lipids of the cephalopods Eledone moschata, Sepia officinalis and Todarodes sagittatus mantle, represent 50.5%, 66.1% and 74.2% of wet tissue respectively. On the other hand the polar lipids of these three species of cephalopods constitute of 80.8%, 94.8% and 93.7% of phospholipids, respectively. The main phospholipids identified were phosphatidylcholine (52.2, 51.3 and 58.4% of total pho...

Global proliferation of cephalopods

Human activities have substantially changed the world's oceans in recent decades, altering marine food webs, habitats and biogeochemical processes [1]. Cephalopods (squid, cuttlefish and octopuses) have a unique set of biological traits, including rapid growth, short lifespans and strong life-history plasticity, allowing them to adapt quickly to changing environmental conditions [2-4]. There ha...
