5. Enoploteuthis leptura (Leach, 1817)
Loligo Smythii Leach, 1817
Loligo leptura Leach, 1817
A rare species, this has been recorded off West Africa (Leach, 1817,
1818a; d’orbigny, 1845), Madeira (Rees and Maul, 1956) and the straits
of Florida (Roper, 1966). Chun’s (1910a) record is thought to be
E . anapsis by Roper (1964). It has been taken from stomachs of
Yellowfin tuna caught near the surface and with open nets fished
to as much as 1 620 m (Roper, 1966). The largest has a mantle length of
7-9 cm (Roper, 1966). During growth the mantle decreases in width,
the fins become longer and the arms and tentacles become shorter
relative to the mantle length (Roper, 1966).
D. Pterygioteuthis
1. Pterygioteuthis gemrnata Chun, 1910
This species has been taken in the South Atlantic (Chun, 1910a;
Thiele, 1921) and the equatorial North Atlantic (Thiele, 1921) near the
surface (10 m) (Fig. 33). Voss (1958) doubts the validity of the species.
The hectocotylus lacks a chitinous hook which is found in P. giardi.
The female has only a right oviduct and one pair of large nidamental
glands.
2. Pterygioteuthis giardi Fischer, 1896
Pyroteuthis (Pterygioteuthis) Giardi Pfeffer, 1912
This little squid has been taken in the western North Atlantic
(Voss, 1956a, 1958, 1960a) (Fig. 33), the eastern North Atlantic
(Fischer and Joubin, 1906; Pfeffer, 1912; Chun, 1913; Joubin, 1920),
South Africa (Massy, 1925), the Indian Ocean (Chun, 1910a), the East
Indies (Adam, 1954), off Queensland and New South Wales (Allan,
1945), New Zealand (Massy, 1916c), off the Galapagos Islands and the
eastern Pacific (Hoyle, 1904b; Robson, 1948) and the southern tip of
South America (Carcelles and Williamson, 1951). It has been caught
near the surface (Massy, 1916~) and with open nets fished to as much
as 2 500 m (Chun, 1910a). The largest recorded male has a mantle
length of 1 - 7 cm (Chun, 1910a) and the largest female a mantle length
of 2.0 cm (Voss, 1958). Males with mantle lengths of 1.6 and 1.7
cm contained spermatophores (Chun, 1910a; Joubin, 1920) and a
female of 1.9 cm had mated (Pfeffer, 1912). The left ventral arm ie
hectocotylized.
During growth, the arms and head become relatively longer and
