Two great hammerhead sharks are now living at SeaWorld Orlando’s Shark Encounter attraction, and they are visible to theme-park guests.

The young male sharks, named Dutch and Dillon, were transferred from Georgia Aquarium in Atlanta in a collaborative effort to protect endangered species. Dutch arrived in Orlando in November, followed by Dillon in April.

“These are our first great hammerhead sharks and we are thrilled to have these extraordinary animals join our population at SeaWorld Orlando,” Jim Kinsler, curator of aquariums at SeaWorld Orlando, said in a news release. “It is our privilege to provide care for this critically endangered species and to bring greater awareness and understanding of this shark to the tens of millions of guests that visit us every year.”

The young sharks currently are about 7 feet long and weigh about 120 pounds. They are expected to reach between 10 and 15 feet in length, eventually. The great hammerhead is the largest of the nine hammerhead shark species. The International Union for Conservation of Nature lists great hammerhead sharks as critically endangered. Their large dorsal fins makes them valuable on the shark-fin market, a threat to all shark species, SeaWorld says.

The theme park’s Shark Encounter features a clear, underwater tunnel for viewing several species of sharks, rays and fish. The tank now hold six species of sharks.

SeaWorld Orlando and Georgia Aquarium are accredited by the Association of Zoos and Aquariums and active in the group’s Saving Animals From Extinction program.
