Introduction

Stoloteuthis weberi, known only from the type specimen, was originally placed in Heteroteuthis. The enlarged suckers on arms II of the male, the apparently large venral shield, the large fins, the strong indentation for the funnel on the ventral mantle margin and the rounded posterior lobe of each fin suggest that this species is closest to members of Stoloteuthis in spite of the lack of fusion of the dorsal mantle margin to the head. Unfortunately little descriptive detail is known for this species. A re-description based on the holoype or additional material is badly needed.

Brief diagnosis: 

A Stoloteuthis with...

  4. Fins
    1. Fin attachment parallel to long axis of the body.
    2. Fin length - 3/4 of ML.

  5. Measurements
    1. Length from tip of arms to posterior tip of mantle - 30 mm.

Comments

This description is taken from Joubin (1902). 

The position of S. weberi in Stoloteuthis is tentative until more characteristics of this species are known. Comparisons with other members of Stoloteuthis is found on the Stoloteuthis page.

Distribution

Type locality: Indonesian waters at 7°35'S, 117°28'E taken at a depth of 700-900 m.

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.
