Enoploteuthis reticulataKotaro Tsuchiya and Richard E. Young
Enoploteuthis reticulata, a large species for the family, attains 130mm DML. It was first described from the stomach of a lancetfish in the Indonesian waters, and is broadly distributed in the Indo-West Pacific.
An Enoploteuthis (Enoploteuthis) with...
- longitudinal and oblique rows of photophores on ventral mantle giving reticulate pattern.
- Hectocotylus with large truncate membranous flap on ventral edge.
- Modified portion with armature.
- Tentacle short, narrow.
- Carpal cluster elongate.
- Two rows of subequal-sized hooks on manus.
- Two rows of suckers on dactylus.
- Integumental Photophores
- Ventral mantle with six longitudinal stripes of integumental organs, that are connected with oblique stripes to form latter-like pattern.
- Ventral head with four longitudinal stripes of integumental organs which connected in each side forming ring-like.
- Ventral side of arm III with a row of organs along almost entire length.
Spawned eggs are ovoid, 1.08 x 0.78 mm, colorless, slightly opaque with a slightly dull, silvery chorion.
Paralarvae are distinguished by their numerous head and mantle chromatophores.
The following illustrations show the characteristic photophore patterns seen on the ventral mantle during development.

E. reticulata is common item in the stomachs of lancetfish, Alepisaurus ferox, and bigeye tuna, Thunnus obesus, in the Indo-Pacific (Okutani and Tsukada, 1981; Moteki et al, 1993).
Paralarvae were captured in the upper 200m (Young and Harman, 1985).
Geographical distributionThis species was first described from New Guinean waters. It is distributed widely in the tropical Indo-Pacific.
