Overview

Brief Summary

Introduction

Traditionally only a single species, C. murrayi, was placed in this genus. O'shea (1999) placed Cirroteuthis magna in this genus on the basis of the similarity of the shells in the two species. These are fragile, gelatinous deep-sea cirrates.

Brief diagnosis:

A cirroteuthid ...

  • with shell with moderate saddle and triangular wings.
  • with normal eyes or reduced eyes lacking lenses.

Comprehensive Description

Characteristics

  1. Eyes
    1. Eyes well developed, lenses present (C. magna) or poorly developed, without lenses (C. murrayi).

  2. Arms
    1. Web nodules absent.
    2. Suckers extend to arm tips.
    3. Cirri may extend to arm tip (C. murrayi) or terminate at web margin (C. magna).

  3. Shell
    1. Shell saddle-shaped but with a saddle of moderate length.
    2. Shell with anterior-posterior length of wings more than 2.5 times length of saddle in this direction.
    3. Shell with wings triangular in lateral view (below).
