Discover Maryland's Herps

​​

Welcome to the wonderfully weird and winning world of amphibians and reptiles that make their home in Maryland!

Collectively called herps (from herpetology , the study of amphibians and reptiles), these animals were once labeled “cold-blooded” unlike birds and mammals that were “warm-blooded”. Today biologists know that herps use environmental temperatures to regulate their body temperatures in a process called ectothermy and the term “cold-blooded” is inaccurate.

Though they share ectothermy, amphibians and reptiles are more different than they are alike. Broadly speaking, amphibians have soft skin easily penetrated by water; they lay their eggs in water or damp places to keep them moist. Reptiles have dry, scaly skin impervious to water; their eggs have a shell that holds moisture for the developing young.

If you've found a herp and aren't sure what group it belongs to, click on the silhouette below to link to the field guide for that group.
