Lycoteuthis lorigeraMichael Vecchione and Richard E. Young
- Males lack elongate tail.
- Posterior abdominal photophores fused into single, broad organ in males.
- No large photophore in a pocket in the musculature of the apex of the fins
slightly dorsoposteriorly to the convex surface of the conus of the gladius in either sex.
Tentacular clubs and club and arm suckers have no known species-specific features.
Note the bright blue, mid-ventral ocular photophore on each eye in one of the title photographs. This blue photophore seems to be typical of members of the Lycoteuthinae. Also red integumental pigment covers (or partly covers due to damage) the other ocular photophores. This pigment would appear to be a color filter that would transmit blue light. Why two different means of producing blue light are needed is unknown
The type locality is the "South Sea" in the Pacific Ocean. Distribution range extends between 23°S and 46°S in the South Atlantic and Indian Oceans (Villanueva and Sánchez, 1993).
A trawl that captured a single male off New Zealand also captured 104 females. The trawl was positioned 20-80 m off the bottom in 500 m of water (Försch and Uozumi, 1990).
