Gromphadorhina portentosa

Madagascar Hissing Cockroaches hiss by forcing air out of a pair of spiracles, or breathing holes, located along the abdomen.  Their hiss can be heard 12 feet away.  Adult males hiss when fighting or when trying to attract a female. Cockroaches also hiss when threatened, as a way to ward off predators.

  • Love this zoo! Great place to get a walk in and the animals are everywhere! The museum/indoor part is very educational too. Has a lot of shade for when it's hot out. Very clean. Friendly staff.

  • The museum gives you a break from the sun on hot summer days and has a great selection of animal exhibits from around the world.  The zoo keeps growing and adding new animal habitats or improving existing ones.  Membership offers reciprocal benefits to other zoos around the country.
