Sound It Out

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. Cockroches 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.
