Acklay

The acklay is a large, non-sentient crustacean creature from the Star Wars universe. This carnivorous beast stands on average at 3 meters tall, has thick skin and is easily provoked. The creature moves about on six legs which it will use to crush and chop up smaller prey.

Biology
The acklay was a three-eyed amphibious non-sentient crustacean native to the planet Vendaxa. Though acklays lived underwater, they could go on land to hunt, which they frequently did, as the lemnai, a creature that lived on the plains of Vendaxa, was their main source of food. As they resided in the oceans of Vendaxa, their eyes enabled them to see in darkness, although they were near-sighted. Despite their crustacean-like nature, acklays also had characteristics possessed by reptiles, such as their powerful jaws filled with sharp teeth. The acklay had a tough, leathery skin that ranged in color from green to brown, another trait from its reptilian heritage. Its belly was more vulnerable than other parts of its body, as the flesh covering it was not as tough as it was elsewhere. Acklays had a bony crest around their neck, used for both intimidation and protection.

These creatures had small stomachs, but were capable of expanding them when necessary. They had a high metabolism, which gave them substantial amounts of energy, but also caused them to starve quickly. Acklays were aggressive creatures, making them favorites in gladiatorial combat.

Each acklay had six deadly claws, used for both pinning an opponent in combat or slicing them. Their limbs were long, allowing them to strike at enemies from a distance. While their claws—actually fingertips covered by hardened skin—themselves had no feeling, hairs on their bodies allowed the creatures the sensation of feeling. These cilia also enabled an acklay to sense the neuro-electric energy of other life-forms. The acklay's exoskeleton was strong enough to be used by some cultures as chitinous personal body armor. Although not high tech, it was occasionally used as a trophy item.

Acklays could be Force-sensitive, although this was an extremely rare mutation. Such creatures could teach themselves to use the Force and could fire Force lightning from their mouths.
