We hope to have this done within the next month. They're not sexually mature. We can't do this type of photography with adult sharks. But we can observe adults' feeding behaviors. In the lab, the team anesthetizes the sharks, much as a person would be in preparation for surgery.
Electronic equipment is attached, and the shark is revived.
The shark is not stressed by the experience, and starts eating almost immediately. We have filmed at the Florida Aquarium in the large, coral reef tank while the public's there, and at Sea World before it opens. In addition to sharks, they study skates and rays. They're so overfished that some are threatened, yet we have so little knowledge of their feeding. Sharks have been here for hundreds of millions of years.
