Smaller than a bulette but far faster, this blind hunter senses it's prey through vibrations, sound, and smell. With an endless appetite, it hunts tirelessly for anything, regardless of size. Fiercely protective of its kill, they will fight to the death no matter the odds.
Sand sharks travel mostly alone, with the exception of mothers and calves. Located in dry, arid environments, they have been known to venture into grasslands if they are starved for prey.
