The next day, Lucas sprinkles the lagoon water with a drug he uses to sedate fish, but the Gill Man avoids the drugged waters. While the other doctors argue over its existence, the Gill Man drags Chico over the boat and kills him. On the boat, David chastises Mark, but when his photograph reveals only seaweed, Mark worries that no one will believe their story unless they bring back the Gill Man's body. They dive, and when the Gill Man attacks them underwater, David takes a photograph and Mark shoots it in the back with a harpoon.

Mark Williams, and the other institute doctors, including Dr. At the institute, marine life specialist David Reed and his girl friend Kay, amazed with Carl's finding, bring the claw to their boss, Dr.
