    1. Arms IV intermediate in lenght; ALI IV = 40-65.
    2. Arms with 12 to 22 hooks and 12-22 suckers (excl. arm IV).
  3. Hectocotylus

     image info
  4. Integumental Photophores
    1. Ventral mantle and head with scattered arrangement of integumental organs.


This is the only species characterized by having a scattered arrangement of integument photophores and lacking the carpal flap.


Vertical Distribution

In the Kuroshio-Oyashio transition zone, this species were occurred abundantly between 0-50m during night.

Geographical Distribution

A. felis is the only cool-temperate species in the genus Abraliopsis. This is distributed in westward the northern Northwest Pacific at 145° E along the Kuroshio-Oyashio transition zone and eastward to northwestern coast of America, and in the California Current southward to northern Baja California (Young, 1972).

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.
