Fan Casting Arrowtongue in Expedition

A solitary predator on the planet, but quite astute, which has an arrow-shaped tongue, which they use to pierce their prey after tiring them out in a quick chase, but lethal when successful. It is a liquivore, which injects digestive juices into the prey's body to make its innards liquefy. It is the first creature that Sanders has contact in this world, being almost caught before being saved by Darwin.
