Kotaro Tsuchiya
Introduction
A. grimpei is a small-sized species attaining 25mm DML. It is easily recognized by the small number of club hooks, more than five silvery eye photophores, and the arrangement of integument photophores on the ventral mantle.
Characteristics
- Tentacle clubs
- Two hooks on ventral side.
- Two rows of large suckers on dorsal side of manus.

- Integumental Photophores
- Ventral mantle with scattered arrangement of integumental organs except for three, narrow, longitudinal photophore-less strips.
- Ventral head with scattered arrangemeant of integumental organs.
- Epidermis
- Thick, fragile, and gelatinous.
Comments
This species resembles A. redfieldi, A. similis and A. omiae in the features of the tentacle club, hectocotylus, and gelatinous epidermis but is different in having the additional small photophores on the eye.
