These guys are from—you guessed it—Madagascar. The insects, which can grow up to 7.5 centimeters long, hiss by forcing air through breathing holes on their bodies. The noise comes in three forms, with specific variations to express surprise, aggression, and even flirtation.

Slightly bigger than the Madagascar hissing cockroach at 7.6 centimeters long, these roaches don’t climb smooth surfaces or fly. Indeed, they’re notable for being easy pets and popular among the cockroach-enthusiast crowd. We’ll pass.

Though it’s the smallest on our list, the giant shining cockroach is still a respectable 5 centimeters long. Though it is known in its native Australia as a domestic annoyance, it’s actually much more sanitary than other species and even can be beneficial to gardens—as long as it stays outside.
Yes, you read that right. This species is most notable for having one of the largest roach wingspans, measuring in at 18.5 centimeters, or more than 7 inches. But that’s not all it’s known for: one of its species has been named the longest cockroach in the world at 9.8 centimeters long, or almost 4 inches!

This Central American native measures up to 60 centimeters long and has begun to spread to Florida. Its spooky name comes from the spot near its head, which may look like a skull. But don’t worry; it won’t bite.
