The zantar slug of Garxxax was a carbon-based, resilient organism, capable of quickly healing maimed or damaged tissue by absorbing nutrients from the soil. This was made possible by their metabolism, to the extent that a zantar slug severed in two could stitch itself back together. They were small enough to fit into a terran's boot. They secreted acidic mucus, which could be used as a form of attack, strong enough to penetrate neosteel. They were not sapient, but possessed strong survival instinct.
In 2501, they were assimilated into the Zerg Swarm, becoming the roaches. The roach inherited its acidic abilities. Abathur later used the similarities between the unassimilated slug and the roach as the basis for a mutation for the roach that allowed its acid saliva to better dissolve poorly armored foes.
