Comments

A major feature that distinguishes Slosarczykovia is the absence of a carpal locking apparatus. The series of "carpal" suckers suggest that a locking apparatus may be present. However, no corresponding series of knobs has yet been recognized.

Distribution

Type locality: Off Wilkes Land, Antarctica. Distribution is circumantarctic waters.

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.
