Gorpions were a species that lived on the Lymax planet.
Gorpion colonies nested underground in tunnels. When threatened, they would screech, open frills of skin around their neck, rush at the threat, and explode. This produced a yellow goo and injured the victim. Kirk and Spock were attacked by Gorpions while making their way through the tunnels to the Gorn hideout. (TOS video game: Star Trek)
