The ventral side of the eighth and ninth plates features a transparent pelvic fin.

The second plate has a pair of long and thin jointed pectoral fins, partially made up of a transparent membrane. The body section is divided into twelve plates, the first six plates featuring long spines growing from the top, providing the framework for a dorsal fin-like membrane stretching between them. Both pairs of eyes are ringed with purple. Low down on the head is a black eye with a white ring in the center and behind this a smaller, simpler eye lacking the white ring seen in the larger eye. Between the mandibles is a small beak-like mouth lined with two rows of forwards-swept teeth.

The jaw section is formed by four long curved mandibles pointed forwards that mesh together towards the back to form an inescapable jaw.

The head is quite large, accounting for around one third of the total body length including mandibles. The top side of the body is red in color whilst the underside is beige.
