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.

Type species.-- Pickfordiateuths pulchella Voss, 1953, by monotypy.
Containing group: Loliginidae


These are small (22 mm ML max.), muscular squids that occupy neritic waters often in association with small patch reefs and seagrass (Voss, 1953). In spite of the accessible habitat, the squid is rarely captured and little is known of its biology.

  5. Photophores
    1. Absent.


The general shape varies greatly between species. P. pulchella is broad with relatively large arms and fins; P. bayeri and P. vossi are slender with small arms and fins. The latter two look look much like a young Doryteuthis.

Brakoniecki (1996) submerged the family Pickfordiateuthidae into the Loliginidae.

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.
