Brief diagnosis:

A neoteuthid ...

Distribution

Type locality: 32°08'S, 08°28'W, South Atlantic, 0-1000 m depth.

The North Pacific specimen came from 28°18.9'N, 154°37.5'W (north of the Hawaiian Islands) from the R/V T. Washington with an IKMT that fished mostly with 3000 mwo. (South Tow 13, Station no. 6- tow 35. Scripps Inst. Ocy.)

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.
