Eudolichostraca

**Nothocanthidae** (lit. "false spikes") is a clade of arboreal Desmostracans.

## Description

Like all Dolichostracans, they have long bodies and limbs to grip surfaces on the underside, letting them cling to tree trunks and clamber among branches. Their whip-like oral tentacles bore into the crevices in the plants’ cuticles and pluck out the malacoforms within.

Nothocanthids themselves are relatively harmless to predators. However, they are Batesian mimics of the venomous Pronocanthids, which help them to ward off predators. As such, they are highly similar in appearance to Pronocanthids, possessing the same general body shape and coloration. They also have long structures on their back that resemble Pronocanthid quills, although they are neither venomous nor able to pierce skin.
