Gundark

"You look strong enough to pull the ears off a gundark."

- Han Solo to Luke Skywalker

Gundarks were large, fearsome predatory animals from Vanqor. Gundarks had 16 claws. To tell someone that they "looked strong enough to pull the ears off a gundark" meant that they were healthy and unusually strong.

At some point prior to Anakin and Obi-Wan's assignment of guarding Senator Padmé Amidala from an assassination attempt, Obi-Wan and Anakin fell into a gundarks' nest, although Anakin reminded Obi-Wan that he went in the nest to rescue Obi-Wan. The gang leader Tasu Leech used a gundark bone as his rifle's grip.

A group of gundarks were present in Lexim's hunting ground on a forest planet.

Behind the scenes
Though gundarks were first mentioned in Star Wars: Episode V The Empire Strikes Back, they did not appear in canon until the first season of the Star Wars: The Clone Wars television series. Their first appearance in any Star Wars media was in the 1981 Marvel comic Star Wars 51: Resurrection of Evil, followed by the Star Wars Legends game Super Star Wars: The Empire Strikes Back, released in 1993.
