New Genus C

Richard E. Young and Clyde F. E. Roper
This is an incompletely known species.
Containing group: Chiroteuthidae


This squid is known only from a badly damaged brachial crown. The structure of the tentacular suckers is unusual and suggests that this squid is distinct from all present species unless they are the tentacular-club suckers of large Batoteuthis scolops which have not been described. The only known specimen was taken from Antarctic waters. We suspect that this damaged specimen belongs to an undescribed chiroteuthid.


  1. Suckers
    1. Club suckers with ca. 8 slender, well separated teeth over distal half of ring merging into tiny teeth on proxomal margin; no enlarged central tooth.
    2. Club sucker stalks appear to be uneven in length.
    3. Club suckers appear to be in four series.
    4. Arm suckers not globular, with ca. 14 pointed teeth on the distal 2/3 of the inner ring merging into very small, irregular teeth on the proximal margin.

    Scanning electron micrographs of the suckers can be seen here


The arm crown was badly stripped. Most protective membranes are missing and no indication of club divisions remains. The lack of an enlarged central tooth on the club sucker is similar to species in the Chiroteuthis joubini species group, but the slender nature of the teeth and their broad separation from one another is unique.


The squid fragment was taken in an open trawl that fished to 2,000 m in Antarctic waters at 57° 21'S., 74° 43'W.

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.
