Oh my goodness! Unless you are a Tree of Life developer, you really shouldn't be here. This page is part of our beta test site, where we develop new features for the ToL, often messing up a thing or two in the process. Please visit the official version of this page, which is available here.

A miniature (maximum observed SL less than 16 mm) hoplomyzontine aspredinid distinguished by the following apomorphies: anterior cranial fontanelle highly reduced and posterior cranial fontanelle absent; paired foramina bordered by supracleithra, supraoccipital and Weberian apparatus highly reduced; eyes absent; premaxillae extremely reduced and toothless; limb of palatine posterior to lateral ethmoid articulation much shorter than anterior limb; lateral line ossicles hypertophied to form an armor of overlapping cresentic plates with dorsal and ventral limbs tilted anteriorly; absence of a row of large unculiferous tubercles along lateral line; postcleithral processes short, rounded ; posterior coracoid processes very short, do not extend past anterior limit of basipterygia; typical banding pigmentation pattern of other hoplomyzontines reduced.

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.
