TLDR
By far the most important of the 28 families of cephalopods represented in the diet of cetaceans are the oceanic Ommastrephidae, Histioteuthidae and the Cranchiidae, with the neritic Loliginidae assuming most importance on the continental shelves.
The N.I.O. combination net (RMT 1 + 8) and further developments of rectangular midwater trawls
An opening and closing net system is described in which 1 m 2 and 8 m 2 rectangular trawls are combined in the same framework; details of the acoustic telemetering and release equipment are included.
The role of cephalopods in the world’s oceans: general conclusions and the future

TLDR
Improvement of the knowledge of the ecology of deep water forms is hindered by poor direct sampling methods and rests largely upon sampling from stomachs or regurgitations of the predators that eat cephalopods.
The diet of sperm whales (Physeter macrocephalus Linnaeus 1758) off the Azores.
TLDR
It seems likely that the sperm whale is obtaining 77% of its food by swimming through luminous shoals of slow-swimming, neutrally bouyant squids and only about 23% by chasing faster swimming, larger cephalopods.
Calorific Values and Elemental Analysis of Eleven Species of Oceanic Squids (Mollusca:Cephalopoda)
TLDR
All the known values are of muscular, negatively buoyant species because they are of value as food for humans but no measurements have been made on the ammoniacal or oily species which are probably as important, or even more important, in the economy of the ocean.
