Armadillo

The armadillo is a small terrestrial animal native to the planet Earth. The armadillo is an quadrupedal insectivore with a snout, tail, claws, and a thick casing of armor for defense.

Trip Tucker kept a figurine of an armadillo in his quarters next to a photograph of himself and his sister. 

When Spock tried to match the sound of the Whale Probe to the sound of an Earth animal aboard the Klingon Bird-of-Prey dubbed "HMS Bounty," a long-nosed armadillo (Dasypus novem cinctus) was one of the animals shown. 

In an attempt to insult Worf on his appearance, just moments before he intended to kill the Klingon, Eli Hollander stated, "'Course, shootin someone as ugly as you, could hardly be considered a crime. Were you just born that way, or did your momma marry an armadillo?"
