REVIEW OF THE SYSTENATICS AND ECOLOGY OF OCEANIC SQUIDS
169
length when the nidamental glands become enlarged and in the male
at about 3.7 cm mantle length when spermatophores are found in
the cirrus. The largest specimen recorded has a mantle length of 5.7 cm.
(Verrill, 1885a). There is no evidence of a limited breeding season.

1. Ctenopteryz siculus (VBrany, 1851)
Sepioteuthis sicula VBrany, 1851
Ctenopteryx jimbriatus Appellof, 1889
Ctenopteryx cyprinoides Joubin, 1894c
Calliteuthis nevroptera Jatta, 1896
This species has been taken in the North Atlantic (Joubin, 1900;
Pfeffer, 1912; Chun, 1913; Degner, 1925; Bouxin and Legendre, 1936;
Voss, 1960a), the South Atlantic (Chun, 191Oa; Thiele, 1921), the
Mediterranean (Vbrany, 1851; Appellof, 1889; Joubin, 1894c; Jattct,
1896; Bianco, 1903; Ashworth and Hoyle, 1906; Naef, 1923; Degner,
1925; Issel, 1925b; Sparta, 1933). It has been taken near the surface
a t night (Sparta, 1933) and in nets fished to a maximum depth of
2000 m (Chun, 1910a). Degner (1925) found that of 21 specimens
8 were a t less than 30 m depth (less than 65m of wire out,), 12 were a t
30-150 m depth (65-300 m of wire out) and only 1 was a t more than
150 m depth (more than 300 m of wire out). Issel (1925b) recorded
10 out of 11 larval specimens a t less than 100 m and the remaining one
at 300 m. Evidence based on specimens taken from fish stomachs
suggests that they live in groups (Bouxin and Legendre, 1936).
During growth, the arms, tentacles and head all become relatively
longer while the body remains almost the same shape (Fig. 29); the
fin becomes relatively longer, being terminal a t a mantle length of
0.8 cm and extending the whole length of the mantle when it reaches
3.3 cm (Chun, 1913; Naef, 1923). The largest specimen has a mantle
length of 5.4 cm (Ashworth and Hoyle, 1906).
The species has been recorded from stomachs of Germo alalunga
(Bouxin and Legendre, 1936), a dolphin (Joubin, 1894c) and from
Chauliodus (Sparta, 1933).
Pfeffer (1912) regarded Chun’s (1910a) specimen as a distinct form
which he named C. siculus chuni.
