American bullfrogs in our Maryland: Mountains to the Sea exhibit!

There are three new male bullfrogs in the Allegheny Streams gallery.

Did you know? The bullfrog is the largest native frog species in North America!

Breeding males emit a deep bass booming call, sounding like “roo-roo-room” or “jug-a-rum,” that can be heard over a distance of more than half a mile.

During the long spring and summer breeding season, males aggressively defend territory, wrestling fiercely with rival males and attempting to mate with as many females as possible.

In Maryland, tadpoles over-winter and transform into frogs during the following summer, depending on food availability and water temperature. In the southern parts of the bullfrog’s range, metamorphosis can occur in as few as 79 days, while in the colder northern areas, metamorphosis can take more than three years.

Be sure to check back every Friday to find out what’s happening!
