WASHINGTON (WCMH) – Zoos throughout the world are throwing it down on Twitter.

After the Smithsonian’s National Zoo tweeted a picture of a 4-day-old baby seal, the game was on.

A woman from Virginia challenged the Virginia Aquarium, sparking a game of one-upmanship between the two facilities.

It wasn’t long before other zoos joined in, including Ohio’s own Columbus Zoo and Aquarium.
