Australiteuthis aldrichiChung Cheng Lu and Richard E. Young
Australiteuthis aldrichi was described from numerous specimens collected from the inshore waters of Northern Australia. This is a dwarf species, the largest squid described was a mature female of 27.6 mm ML. The holotype is a mature male of 21.3 mm ML. The small squid has never been observed alive.
A myopsid squid ...
- with peculiar funnel locking-apparatus containing a boomerang-shaped groove.
- with fins separated from one-another and with posterior lobes.
- with dumbell-shaped photophore on ink sac.
- Funnel locking apparatus with subcircular shape and "bisected by a boomerang-shaped groove running anteroposteriorly. Anterior wing of the boomerang-shaped groove deep, with wide anterior end, groove deepens and becomes slightly narrower posteriorly to form deep, broad pit. Pit becomes a narrow and shallow groove posteriorly and turns medially forming posterior limb of the boomerang, posterior end of groove slightly widened." (Lu, 2005).
- Mantle component does not reach anterior mantle margin.
- Fins large, round, separate (length 47-63% of ML, width 80-104% of ML); separation at posterior end inconspicuous.
- Fins with free anterior and posterior lobes. image info

- Large dumbell-shaped photophore present. The photophore appears to contain a large population of bacteria (Lu, 2005). image info

Figure. Histological section through one arm of the photophore. Note the inksac surrounding the photophore, the laminated structure (at the left) that presumably houses luminescent bacteria and the lens-like tissue (center top). At the far right is the rectum. Photograph from Lu (2005).Shell
Type locality: Joseph Bonaparte Gulf, Western Australia at 14°07.30S, 128°02.00'E. In addition to Joseph Bonaparte Gulf, squids have been collected from inshore waters near Darwin and Paupa New Giunea, which suggests a rather broad distribution in shallow waters of this general region.
