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.

You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.

Tree from Stanger & Baumann 1993.
Containing group: Taeniopterygidae

Introduction

Thirteen species of Taenionema are currently recognized (Stanger & Baumann 1993). Most are found in western North America with a single species in eastern North America and another single species found in Japan and eastern Asia.

Characteristics

Stanger and Baumann (1993) used the suggestions of Ricker and Ross (1975) to list the synapomorphies of the genus as: 1. The epiproct is narrow with the tip bent back or otherwise modified. The tip is sharply pointed from a lateral aspect and slightly scooped out behind. 2. The basicercal processes are rounded, elongate, either fleshy or narrow, and are directed mostly dorsaly with the tip narrowed and curved back. 3. The posterolateral corners of sternum 9 in the male are slightly to moderately elevated, with the middle region of the hind margin of the sternum depressed. Stanger and Baumann (1993) produced the matrix for the species in the genus along with the tree that is used on this page.

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.
