Students slide, slither and hop into herpetology, the science of reptiles. We'll get up close and personal with live snakes, lizards and turtles in order to study the features which make this class of animals unique. Discover that snakes are smooth and dry, lizards have no earlobes, and geckos can lick their eyeballs!

Experience an adventure in science without leaving the classroom. These programs include a general introduction to a science topic and hands-on, interactive activities. For the health and safety of the animals, this program can only be booked within a two hour drive of OMSI.

A minimum of 2 weeks' advance notice is required for all registration requests. If you have questions, please contact us at 503.797.4661 or
