Critokian

Critokians were a race of two-meter tall, bipedal, sentient beings hailing from the planet Yavin Four. They lived in tribes in the jungles and had tentacle-like fingers to manipulate objects as well as large claws to kill their prey. They were capable of both swimming and running extremely fast, which was useful when they were hunting prey. They had six holes on their head which were used to breathe both on land and in water, as well as to communicate through hoots and whistles. The upper portian of their head/body housed a complex nervous system whereas the lower portion contained their heart, digestive and circulatory systems. Several Critokians had been seen off of the planet Yavin Four, and were skillful bounty hunters.

Behind the scenes
Critokians were created by Ooi Say Hien, a Star Wars fan, as part of the Design An Alien contest held in the Star Wars Galaxy Magazines. The entry was picked as the overall winner in the under 16 years old category but it is not known exactly how canon the species is.
