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

  1. Tentacle clubs
    1. Two hooks on ventral side.
    2. Two rows of large suckers on dorsal side of manus.

  2. Hectocotylus
    1. Right ventral arm of male hectocotylized.

  4. Integumental Photophores
    1. Ventral mantle with scattered arrangement of integumental organs except for three, narrow, longitudinal photophore-less strips.
    2. Ventral head with scattered arrangemeant of integumental organs.

  5. Epidermis
    1. 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.

Distribution

Geographical distribution

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.
