Abralia steindachneri Weindl 1914

Kotaro Tsuchiya
Containing group: Abralia

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.

Characteristics

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

  2. Hectocotylus
    1. Right ventral arm of male hectocotylized.
    2. Hectocotylus with two different sized off-set flaps.
    3. Proximal part of the modified portion with armature.
  3. Eye Photophores
    1. Five major complex organs: two large, terminal, opaque organs and three intermediate, silvery organs; some additional small organs present.

  4. Integumental Photophores
    1. Ventral mantle with four longitudinal stripes of integumental organs separated by photophore-less, broad stripes.
    2. Ventral head with indistinct but lineally arranged organs.

Nomenclature

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

Distribution

Geographical distribution

Type locality of this species is the Red Sea. It is associated with shelf waters of the West Indian coast, Andaman Sea, Torres Strait, northern coast of western Australia, Ryukyu Islands, and the submarine banks off East Africa.

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.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
