Cool Cockroaches?

The Madagascar hissing cockroach is wingless, slow moving, docile, has no odor, and does not bite. They can grow to be 2-3 inches long. Male roaches have two prominent protrusions on the thorax that look like horns. Females have a smoother thorax. Hissing is produced by expelling air from spiracles and is used as a defensive behavior.

They are native to the island of Madagascar and live near or on rotten logs in savannah areas. Their diet consists of decaying fruit and vegetation, and they are scavengers.

Conservation Status: Not threatened.
