Dolphins' 'remarkable' recovery from injury offers important insights for human healing
Date:7/20/2011

have developed protective strategies that allow them to cope with water-borne microflora. [Dr. Zasloff's] letter suggests a unique and intriguing hypothesis which may begin to explain how dolphins, and perhaps other cetaceans, survive significant soft-tissue wounds in the wild without the aid of antibiotics or clinical care."

"It is very clear from working with marine mammals that the ability to heal is 'enhanced' from what we see with terrestrial mammals," says Leigh Ann Clayton, DVM, DABVP, director of the Department of Animal Health at the National Aquarium, who also advised Zasloff. "Dr. Zasloff proposes some fascinating mechanisms of action in healing. It is exciting to begin exploring these mechanisms more completely."

In his letter, Zasloff presents the case histories of two shark-bitten dolphins, Nari and Echo, at the Tangalooma Wild Dolphin Resort in Moreton Island, Australia. The reports document the healing process of the dolphins with photos to eloquently demonstrate how and how quickly two dolphins heal from severe shark injuries.

"The Tangalooma dolphin care team is continuously astounded at the remarkable natural ability of the dolphins that visit us, in overcoming severe shark bite injuries with what seems to be indifference," says Trevor Hassard, director of Tangalooma. "We learn so much from the lives of other animals. Perhaps Dr Zasloff's contribution will bring the dolphin's remarkable healing capacities to the attention of the medical research community."

"My hope is this work will stimulate research that will benefit humans," says Zasloff. "I feel reasonably certain that within this animal's healing wounds we will find novel antimicrobial agents as well as potent analgesic compounds."
