Dimple Backed Vroxel

The Dimple Backed Vroxel is a species of Venusian Vroxel that forms a symbiotic relationship with the Mountain Meat Beatle.

Instead of a cranium, this strange beast has a large bony file which sits below its tiny mouth aperture and feeding arm. The Vroxel is known to feed by finding a Mountain Meat Beetle and using this appendage to husk away at barnacle like growths on its outer shell. It picks these fragments up with its upper feeding arm and noshes away.
