Serrated teeth of a crabeater seal
A view of the serrated teeth of a crabeater seal. The seals use their teeth to capture Antarctic krill, their primary prey. While they don't actually eat crabs, they do feed by swimming through schools of krill with their mouths open, then trapping both krill and water in their mouths, lock their ...This is an NSF Multimedia Gallery item.
