Opisthoteuthis persephoneRichard E. Young and Michael Vecchione
O. persephone was described from 8 specimens taken off Western Australia the largest of which, apparently, is the holotype which is 330 mm in arm span (arm tip to arm tip). This species needs to be redescribed from new material from the type locality.
- Arms and web
- Female: largest suckers possibly numbers 12-18, nearly uniform over much of arm.
- Cirri with narrow pockets into which they can contract.
- Sucker numbers (holotype): arm I - 78, arm II - 78, arm III - 72, arm IV - 72. [O'Shea states that arm sucker counts reach 93.]
The above description is taken from Berry (1918) except where indicated otherwise. More details of the description of O. persephone can be found here although the species has been incompletely described.
O. persephone differs from the New Zealand species O. mero in the number of primary gill lamellae (almost always 6 vs almost always 7) (O'Shea, 1999). It differs from the sympatric O. pluto in its pigmentation (Berry, 1918) and fewer gill lamellae (usually 6 vs 8).
Type locality: 42 miles south and east of Genoa Peak, Victoria, in the great Australian bight, 480 m. Known also from off Eucla, Western Australia from depths of 277 - 554 m (Berry, 1918).
