It was observed that this species habitually attach itself to the underside of various hydroids or any underwater substrate. It is seen hunting and foraging after sunset. It preys on small shrimp by grappling with its small arms. The species attack the dorsal side of prey to immobilise it within seconds, then swim or attach to substrate while consuming prey.
