Even in total darkness, a gray seal gets its meal. Sensitive whiskers (a.k.a. vibrissae) can detect currents created by the seals' prey. They regularly dive 230 feet beneath the water's surface for food, but are capable of diving much deeper.

At 11:15 a.m. daily, watch keepers train our seals or sea lions and learn more about these beautiful marine mammals! PLAN YOUR VISIT: http://s.si.edu/2h3CN1W.
