This tree diagram shows the relationships between several groups of organisms.

The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.

Containing group: Onychoteuthidae

Introduction

Kondakovia is a sub-Antarctic to true Antarctic genus of large squids (adults to 740 mm ML), primarily set apart from similar species in Onykia by the presence of marginal sucker series on the tentacular clubs in subadults to adults. 

Brief diagnosis:

An onychoteuthid ...

Characteristics

  1. Tentacles
    1. Tentacular club with 23-33 hooks flanked by complete series of small marginal suckers.

  2. Mantle
    1. Mantle soft and fleshy.
    2. Mantle skin with longitudinal ridges in large specimens of K. longimana (Clarke, 1980) and reticulate skin in K. nigmatullini (Laptikhovsky, Arkhipkin & Bolstad, 2008). The photographs below compare the skin of K. longimana (left, middle) with the skin of Onykia robsoni (right).

  3. Gladius
    1. Gladius not visible beneath skin in dorsal midline.
    2. Gladius thin and fragile with 3 pairs of narrow longitudinal ribs: one borders rhachis, one at marginal rim and one inbetween the other two.
    3. Gladius rostrum 5-13% of ML (Laptikhovsky, Arkhipkin & Bolstad, 2008); 2-5% of ML (Clarke, 1980).
    4. Gladius rostrum tricornate dorsally in cross-section along conus field; convex rib present over full length of flat dorsal surface.

Distribution

This genus 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).

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.
