REVIEW OF THE SYSTEMATICS AND ECOLOGY OF OCEANIC SQUIDS

4. Maturity
i. the size a t the onset of maturity-male and female
ii. the ultimate size reached by males and females and the
species (if the largest specimen is unsexed). These should
indicate the usual size attained although it is difficult to be
absolutely sure of extracting all the largest specimens from
the literature. Dorsal mantle lengths are used to indicate
size but, when these are not available, ventral mantle lengths
are used. Mantle length is measured from the extreme tip of
the body to the anterior edge of the body in either the
ventral or dorsal midline. Total length is measured from the
extreme tip of the body to the end of the longest tentacle.
iii. the sex ratio
5. Mating
i. Hectocotylus. The arm concerned and any unusual details
about it are noted
ii. Site where the spermatophores are deposited
iii. Mating behaviour
6. Egg laying
i. Season
ii. Fecundity
iii. Process of egg laying and details of behaviour
7. Food
i. the type
ii. the size
iii. bites
8. Predators
9. Economic uses
While all these subjects have been considered for all taxa, a few
additional pieces of information have been inserted and a slight rearrangement has been thought advisable in a few instances.
11. ARCHITEUTHIDAE
The single genus in this family has so many ill-described and poorly
known species that it is pointless to treat each species separately.
Details of the types of named species are given in Table I.
