Discover Maryland's Bats

Description: Maryland has ten species of bats that lead varied lives. Some reside in Maryland all year long, and some migrate through Maryland in the spring and fall. Some species of bats live in groups called colonies and others live by themselves or in small families. Bats belong to the order Chiroptera, which means “hand-wing.”  Their hand is literally their wing and they are the only mammals that can fly. Bats are more closely related to people than to mice and like humans, have hair, and feed their young milk.

Discover Maryland's Reptiles & Amphibians

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