Introduction

A. steindachneri is a relatively large species for the genus, and attains 50mm DML. It is easily recognized by the presence of a distinct arrangement of longitudinal photophore stripes on the ventral mantle, large numbers of club hooks, and a distinct eye photophore pattern. This species is broadly distributed in the Indo-West Pacific Ocean where it is associated with shelf waters.

Nomenclature

Nesis and Nikitina (1987) downgraded the Pacific A. renschi to a subspecies of A. steindachneri.

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.
