As the Chukchi Sea experiences longer periods without ice and the female and juvenile walruses spend more time resting on land, it makes them vulnerable to human and predator activity.

Before it’s over, we’ll see grizzly bears, moose, elephants, walruses, rhinos and more — an amalgam of the more than 75 detailed habitat displays that are at the heart of the museum’s exhibits.

Aside from a handful of walruses and polar bears, the crew are entirely alone.

Imagine a walrus-like creature with dentition remarkably similar to modern walruses: A quartet of post-canine teeth, a large lower canine tooth and a short, fused vertical midline on their lower jaw.

It killed hundreds of sea lions and walruses, but also began to kill house cats and other wild animals.
