No, but then again, many trainers don’t realize that sableye have a tendency to bite anything that gets within range of their mouths. You see, anonymous, sableye are effectively blind. Their natural habitats are deep caves, and the crystallization process their eyes undergo leave them nonfunctional. Instead, sableye navigate their world through a combination of thermal sensitivity, echolocation, and scent, rather than actual sight. That is to say, although they can tell when something is in their way and although they can tell the difference between food and something that isn’t food, they cannot tell the difference between their trainer and a threat—at first, anyway. So putting a body part anywhere near a sableye’s face confuses them. They perceive it as a threat, and thus, they bite.
Thus, it’s vitally important that whenever you first obtain a sableye, you train it to recognize your voice first. Speak to it as you approach it, and allow it to take in your scent while you keep yourself out of arm’s reach of it. Never touch a sableye unless it’s been acclimated to you.
