Calot (The Grim Adventures of Billy & Mandy)

Calots are medium-sized Martian predators, known to feed on Martian Zombies.

Biology
They're yellow-skinned reptilian creatures which walk on six short legs. They have bulging eyes and sharp teeth, including a pair of tusks protruding from their lower jaws, and also have a dorsal sail. They can be extremely loyal to those they have befriended and will follow them and protect them from danger.
