The tail was a large tail fan, composed of three [8] [35] pairs of large, lateral fin-shaped lobes and one terminal lobe-like tailpiece. [35] Previous studies suggest the tail fan was used to propel it through Cambrian waters, [ 20 ] [ 36 ] while further hydrodynamic study rather suggest it was more adapted to provide steering function.

Their chief common name, bristlemouth, comes from their odd, equally sized, and bristle-like teeth. They are typically black in color which provides camouflage from predators in deep, dark waters. They mainly feed on zooplankton and small crustaceans due to their small size.
Several odd-shaped growths, known as cerata, jut out of the sea slug’s back and side. Each growth has two bulges and looks almost like an observation tower. A Phestilla arnoldi, or Arnold’s ...
Praya dubia zooids arrange themselves in a long stalk—usually whitish and transparent (though other colours have been seen [5])—known as a physonect colony. [6] The larger end features a transparent, dome-like float known as a pneumatophore, [7] filled with gas which provides buoyancy, allowing the organism to remain at its preferred ocean depth.
