REVIEW OF THE SYSTEMATICS AND ECOLOGY OF OCEANIC SQUIDS

7. Chiroteuthoides hastula Berry, 1920
69'22'W and 200-0 m and has a mantle length of 1.0 cm.
Only known from Berry's specimen, this was taken at 28'59"
XVII. LEPIDOTEUTHIDAE
The scaled squid " Lepidoteuthis grimaldii, while being closely
allied to the preceding family in many respects (Clarke and Maul, 1962))
has a number of differences which distinguish it from both Chiroteuthis
and Nastigoteuthis so that it is convenient to place it in a distinct
family for the present.
A. Lepipidoteuthis
1. Lepidoteuthis grimaZdii Joubin, 1895
This species has been collected in the North Atlantic (Joubin,
1895a, 1900; Rees and Maul, 1956; R. Clarke, 1966; Clarke, 1960, 1964;
Clarke and Maul, 1962) and the South Atlantic a t 31'11's 33'13'W
(Merritt, 1964). One young specimen was taken in an open net fished
to 245 m and another in a closing net fished 100-270 m; both nets
were supplied with depth gauges (Clarke, 1964). Although these are
the only young stages known, they show the changes of form associated
with growth and there is some suggestion of a fairly rapid change
when the mantle length is round about 7.0 cm (Fig. 44). At this size
the arms and head become relatively longer, the tentacles relatively
shorter and are lost later, and the body relatively broader. After this
rapid change, growth appears to be isometric. The adult " scales ) '
are represented by papillae with knobs on in the juveniles. The largest
mantle known was 97.0 cm in length when fresh and that is of a female.
Nidamental glands of three females are very large, suggesting that a
large egg mass is secreted. Although the ovaries are spent, the oviducts
are full of eggs and this possibly suggests that the eggs are stored there
temporarily prior to laying (Clarke and Maul, 1962). The two juveniles
were caught in April and June.
All specimens, with the exception of the juveniles, have been taken
from stomachs of predators or immediately after regurgitation. Known
predators are the Sperm whale in whose diet this squid is quite important to judge from beaks in the stomach (Clarke, 1962a), Qrampua
grisew (Joubin, 1895a), Aphanopus carbo (Clarke and Maul, 1962) and
a tuna probably Qermo obesw (Clarke and Maul, 1962).
