Discoteuthis sp. B

Richard E. Young and Michael Vecchione
Containing group: Discoteuthis

Introduction

A single badly damaged immature male squid (NMNH no. 815487) taken in the Atlantic Ocean at 08°11'S, 14°12'W appears similar to D. laciniosa judging from the funnel locking apparatus. Most characteristics that would confirm the identification have been lost. However a portion of one tentacular club remains and the large suckers have an unusual dentition.

Diagnosis

A Discoteuthis ...

Characteristics

  1. Tentacles
    1. Largest suckers of manus with numerous (ca. 40), pointed teeth around entire margin of inner ring.

Comments

The strikingly different dentition of the manus suckers could indicate that either (1) this is a different species from those previously described, or (2) males of D. laciniosa have a different dentition than females, or (3) there is more intraspecific variation in sucker dentition of D. laciniosa than previously thought. We have made no attempt to describe more details of the badly damaged specimen. Our objective is simply to point out an inconsistency in our understanding of Discoteuthis.

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, 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.
