Their hissing is not a vocal sound, but actually comes from their Spiracles which are holes located up and down the sides of their bodies. These spiracles are not only how they breathe, but are also used to expel air when they are threatened like letting air out of a balloon! | Wildlife Images Rehabilitation & Education Center | Facebook

Gromphadorhina portentosa or the Madagascan hissing cockroach is named for its ability to create a pronounced hissing sound by forcefully expelling air from respiratory tracts called "spiracles". They use this either as a method of alarming would-be predators, or in the case of males, to communicate dominance between other males, or signal availability to females. | Naturetalksback with Dr. Cyren Asteraceya | Facebook
