Even sharks receive training! 🦈 Zebra sharks are fed this way to make sure they each get their fill, while also reinforcing target training behaviors in a rewarding way. Feeding zebra sharks is similar to feeding vacuum cleaners with teeth: they suck in the squid or fish before crushing it with their powerful teeth. In the wild, these sharks can squeeze into narrow crevices in the reef to reach prey inside. | Shedd Aquarium
