Given that their kind has been roaming the oceans for over 200 million years, you might say six-gilled sharks are the senior citizens of the marine world. One of the reasons they’ve been around so long: Though they typically stay in deep water, they’ll periodically head to shallower waters to locate food and mate.

In other words, they’re willing to move beyond their comfort zone to find what they need to thrive. We should be as bold.
