Enoploteuthis jonesiKotaro Tsuchiya and Richard E. Young
Enoploteuthis jonesi, a relatively small-sized species for the genus, attains 70mm DML. This species resembles the sympatrically occurring species E. higginsi, but separable by the small numbers and relatively narrow stripe arrangement of integumental photophores on the mantle and head.
An Enoploteuthis (paraenoploteuthis) with...
- longitudinal photophore rows on head narrow, consisting mostly of one photophore width.
- longitudinal photophore rows on mantle narrower and more distinctive than in E. higginsi.
- Tentacle long, with distinct club.
- Carpal cluster oval.
- Two rows of different-sized hooks on manus.
- Four rows of suckers on dactylus.
- Hectocotylus with large truncate membranous flap on ventral edge and small semilunar one on the dorso-distal edge.
- Modified portion partially lacks armature.
- Integumental Photophores
- Ventral mantle with six longitudinal narrow stripes of integumental organs.
- Ventral head with four narrow longitudinal stripes of integumental organs that are interconnected at each end forming ring-like pattern.
- Ventral side of arm III with a row of organs in about half of the arm length along the base of aobral keel.
This species closely resembles E. higginsi in almost all taxonomical characters. It is separable from E. higginsi by the small numbers of integumental photophores on the ventral head and mantle. In E. higginsi, each photophore stripe is formed by a few rows of organs with scattered intermediate organs while stripes are found by mostly by a single row of organs.
Spawned eggs are ovoid, 0.94 x 0.77 mm, often with slightly greenish color, with a smooth chorion and distinct perivitellin space usually at both animal and vegetal poles.
ParalarvaParalarvae with distinctive chromatophore pattern on mantle. Elongate clubs with relatively small suckers separates these paralarvae from those of E. higginsi.
This species is distributed in the equatorial Pacific waters from the Northwest Pacific and Hawaii to Melanesia (Burgess, 1982; Riddell, 1985; Tsuchiya, 1993).
