Registration is still open for “Newport Aquarium Presents: Croc Talk” at 2 p.m. Saturday at the Arts Park Pavilion in New Castle.

Learn what it means to be a reptile and have an in-depth conversation about Crocodilians: crocodiles, alligators, gharials and caimans. Discover the differences between each species and in the end be able to tell them apart with just a glance!
