Bolt-tongue

A polar cousin of the Arrowtongue, the Bolt-tongue is a Darwinian predator which uses a large arrow-tipped appendage to kill its prey. Roughly the length of an oversized Utahraptor, the bolt-tongue possesses a sonar bulge in the form of an arc running down its head. Like all predators on Darwin IV, it has no eyes and pins its prey with sonar.
