Banshee (Star Wars)

Banshees are a species of non-sapient crustacean-like life forms from the planet of Umbara. Due the dark atmosphere of the planet, the Banshee species evolved to give out a bioluminescent glow, most likely to attract food. During the Clone Wars, when the Confederacy of Independent Systems took control of the planet Umbara and convinced the native Umbaran people to join their military, a squad of Clone Troopers led by Besalisk Jedi Master Pong Krell were attacked by a pair of wild Banshees. Attacks like this were performed by various other Banshee during the Battle of Umbara, probably because the Banshee believed the Clone soldiers of the Republic might be easy to catch prey.
