Enoploteuthis galaxiasKotaro Tsuchiya
Enoploteuthis galaxias is associated with the temperate shelf waters of northern New Zealand and South Australia. This species resembles to North Pacific species E. chuni both in morphology and ecology.
- Tentacle long, with distinct club.
- Carpal cluster oval.
- Two rows of different-sized hooks on manus.
- Four rows of suckers on dactylus.
- Hectocotylus with two different-sized offset flaps.
- Modified portion with armature.
- Integumental Photophores
- Ventral mantle anteriorly with six longitudinal stripes of integumental organs, which are interconnected with addiotional organs to form fenestrae; stripes become diffused posteriorly; fenestrate arrangement obscured with growth due to increasing numbers of organs.
- Ventral head with three wide longitudinal stripes of integumental organs.
- Ventral side of arm III with a series of organs along almost entire length.
Taxonomic status with the south temperate Pacific species, E. semilineata Alexeyev, 1994 is uncertain. It is known from E. chuni that the photophore arrangement changes with growth due increasing of numbers of organs causing stripes to diffuse posteriorly.
This species seems to be a mesopelagic boundary species (Young, 1995).
Geographical distributionThis species was known only from the shelf waters of South Australia and northern coast of New Zealand (Riddell, 1985).
