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: Lepidoteuthid families

Introduction

Some octopoteuthids reach a large size (160 cm ML); all have a distinctive appearance and are not easily confused with any other squids. Tentacles do not grow much beyond the paralarval stage. They are lost in subadult Octopoteuthis and form only minute appendages in subadult Taningia. The mantle is broad and weakly muscled; large muscular fins apparently provide most of the force for swimming. The short arms carry two series of hooks except near the tips where they are replaced by two series of suckers. Some or all arms terminate in photophores. Arm tips of Octopoteuthis are frequently lost during capture.

Brief diagnosis:

A member of the lepidoteuthid families ...

Characteristics

  1. Arms
    1. Arms with hooks in two series, replaced by suckers in two series near arm tips.

  2. Tentacles
    1. Tentacles reduced or absent in subadults and absent in adults.

  3. Fins
    1. Fins large, broad, muscular; fused to one another along dorsal mantle midline.
    2. Fin length nearly equals mantle length.

Nomenclature

A list of all nominal genera and species in the Octopoteuthidae can be found here. The list includes the current status and type species of all genera, and the current status, type repository and type locality of all species and all pertinent references.

Life History

Mature males lack a hectocotylus but have a large penis that, apparently, can extend well beyond the mantle opening.

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.
