Animal Update - January 11

Published January 11, 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 visits. 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!


Our freshwater exhibit welcomed some new additions this week!

Brown bullhead catfish

Also referred to as a "mud cat," this species thrives in lakes and ponds with muddy conditions.

The bullhead catfish is an opportunistic bottom feeder. Their diet consists mostly of insects, leeches, snails, fish, and clams.

Previously only found in the United States, the bullhead catfish has become a global invasive species (they are especially harmful to freshwater ecosystems in Europe, Chile and parts of New Zealand).

Greenside darter

A greenside darter was added to our Northern Streams gallery. The greenside is the largest of the darter genus, reaching a standard length of approximately five inches.
