Introduction

Kondakovia longimana is a large squid (adults to 740 mm ML) of the Southern Ocean (Kubodera et al. 1998).  The three individuals of the type series were taken from the surface and at a depth of 50 m. All three had been feeding heavily on euphausiids (i.e. Euphausia superba). Clarke (1980) examined the stomachs of 7 squid and found remains of fish, crustacea, squid and sponges.

Distribution

The type locality is just north of the South Orkney Islands. K. longimana is thought to occupy epi- and mesopelagic waters in the Southern Ocean where it may be circumpolar and reach northward to South Georgia and the Tasman Sea (Kubodera et al. 1998). A map of the distribution of this species can be found here.

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.
