This draws comparison to the elongate flexible caudal spines and broad swimming flaps of Mobula rays, which resemble the outline of the new taxon.

This is in reference to the dramatic yellow, red, and black coloration of the two known specimens, and to the arid conditions of the type locality.

It is described as having more lateral flaps than any other known lobopodian or radiodont; at least 18 down the length of the trunk, becoming smaller towards the caudal spine in an acuminate distribution.

It is thought to have been pelagic, feeding on small prey in the water column, with elongate compound eyes on the underside of the head, also inferred from Kerygmachela.
