REVIEW OF THE SYSTEBUTICS AND ECOLOQY OF OCEANIU SQUIDS
189
the Philippines (Voss, 1963a), Japan (Chun, 1910a, Sasaki, 1916) and
off western North America (Pearcy, 1966).
The species has been taken at the surface (Massy, 1913; Joubin,
1920) and in open nets fished to 2 000 m (Degner, 1926) but most of
them were taken at less than 1000 m and Degner (1925) found that
out of 14 small specimens (less than 2.2 cm mantle length) one was
taken at less than about 30 m (65 m of wire out), 9 were taken at
30-150 m (65-300 m of wire out) and 4 were taken at more than about
150 m (more than 300 m of wire out). Pearcy (1965), on the other hand,
caught no specimens in 72 tows of a trawl fished at 0-200 m, 0.04 per
hour in nets fished at 0-500 m and 0.02 per hour in nets fished at
0-1 000 m.
The largest specimen, a female, has a mantle length of 13.7 cm
(Adam, 1952); its nidamental glands are 3.0-3.5 cm long and the eggs
are 1.0 mm in diameter. Nearly all the young stages taken in the
North Atlantic were caught between May and September (Pfeffer,
1912; Joubin, 1920; Degner, 1925; Bouxin and Legendre, 1936). During
growth, the arms and head become relatively longer and then shorter,
the tentacles become relatively longer and are later lost altogether,
the body becomes relatively wider and then narrower and the fins
become relatively longer (Fig. 35).
Specimens have been removed from the stomachs of Germo alalunga
(Bouxin and Legendre, 1936) and Tursiops truncatus (Rancurel, 1964).
3. Octopoteuthis Zongiptera Akimushkin, 1963
The type was taken from a Sperm whale's stomach caught at
20"s 26"W. It has a mantle length of 69.0 cm. Akimushkin (1963) states
that beaks of this species are fairly common in Sperm whale stomachs
taken in the Kuril region. To suggest such an extension in the range
on the basis of b'eaks alone seems most unwise at our present stage of
knowledge.
B. Octopodoteutbpsis
The status of this genus is doubtful. Adam (1952) considered that it
should possibly be united with Octopoteuthis while Voss (1956b) believes
that the separation into a distinct genus is justified.
1. Octopodoteuthopsis megaptera (Verrill, 1885)
Ancistrocheirus megaptera Verrill, 1885a
This species has been taken in the western North Atlantic at
