"Chaparral" is spelled with one "P" and two "R"s".
"smaller inside"? What do you mean by that? "It's signature" should be "its signature".
"while can be" was probably meant as "while they can be".
It's odd to say 25 mm instead of 2.5 cm.
It's a small description. Can you add a little more? I know some tiny insects that live among leaf litter are blind. How good is this one's vision? I figure its vision is probably fairly good, which does bring up why it needed the whiskers. Are its foods often hidden from the eye?
