Animal Update - February 22

Published February 22, 2013

Between our Baltimore and Washington, DC, venues, more than 17,500 animals representing 900 species call the National Aquarium home. There are constant changes, additions and more going on behind the scenes that our guests may not notice during their visit. We want to share these fun updates with our community, so we're bringing them to you in our weekly Animal Update posts!

Check our blog every Friday to find out what's going on... here's what's new this week!

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

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

American bullfrog

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!
