Denver Zoo told to be on "alert" after Dallas disappearances

• The Association of Zoos and Aquariums issued a statement Tuesday urging its members — including the Denver Zoo — to "be extra cautious and alert" until the Dallas culprit is caught.

What they're saying: "Unfortunately, as the events in Dallas show, motivated individuals can and do find ways to breach those security measures," association spokesperson Rob Vernon tells Axios Denver. "We will learn from these unfortunate incidents, and our members will be better prepared as a result."

By the numbers: The Denver Zoo is home to 3,000 animals representing 450 different species, spokesperson Jake Kubie tells us.

• Roughly a third of them are classified as endangered, critically endangered or extinct in the wild.

Threat level: Although some Denver Zoo creatures have managed to make a run for it in the past, none have knowingly ever been poached from their habitats, Vernon says.

• The recent incidents involving the escape, death and apparent theft of animals at the Dallas Zoo are also rare nationwide, Vernon adds.

State of play: The Denver Zoo declined to comment on its safety protocols and whether it was ramping up security.

• However, every association-accredited facility must follow certain standards that call for keeping animals and guests safe, including protocols like properly securing habitats.
