Introduction

The single mature male was taken from the stomach of the fish Alepisaurus ferox. Nevertheless, the small squid (9.5 mm ML) was in good condition but with some damage to the eye lenses and the viscera.

Brief diagnosis:

A member of New Subfamily with ...

Characteristics

  1. Arms
    1. Arms IV with two sucker series throughout arm.
    2. Arms I-III with biserial suckers on proximally (ca. 8 suckers), multiple series (ca. 10-15) of tiny suckers on long stalks on distal three fourths.
    3. Transition abrupt with 2-3 suckers of intermediate size between proximal large and suceeding small (ca. 1/5 diameter) suckers.
    4. Most proximal arm sucker not distinctly larger than following sucker.

Comments

More details of the description of New Species A can be found here.

Species boundaries cannot be reliably drawn with so few specimens. However, in addition to the characters listed above, species A seems to differ from species B in its much smaller size, differences in chromatophore distribution (e. g., nuchal fusion, ventral head, fins), the more posterior position of the fins and, possibly, differences in the funnel valve.

Distribution

New Species A was taken from the stomach of Alepisaurus ferox captured within the EEZ of New Caledonia on Jan. 27,  2004 at 22°29'S , 166°15'W  (Sample: Palinstru03/10/2).

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.
