Gorpion

A species which lived on the Lymax planet

Name
Scotty dubbed these creatures Gorpions by combining the words "Gorn" and "scorpion"

Behaviour
Gorpion colonies nest underground in tunnels. When threatened, they will screech, open frills of skin around their neck, rush at the threat and explode. This produces a yellow goo and injures the victim. Kirk and Spock were attacked by Gorpions while making their way through the tunnels to the Gorn hideout. Star Trek game (TOS)

Vulnerability
Gorpions are susceptible to all weapons.
