Michael Zasloff, a researcher at the Georgetown University Medical Center, has discovered that bottlenose dolphins have "miraculous" healing powers

: within several weeks they can heal from basketball-sized injuries, without any lasting disfigurements. Moreover, the injuries, presumably from clashes with sharks, don't seem to cause the animals any apparent pain and don't become visibly infected. Several abilities seem to be working together to promote healing; for example, Zasloff hypothesizes that bottlenose dolphins

prevent bleeding to death by restricting blood flow to certain areas of their bodies, giving large gashes time to clot. [Read more (and see pictures) at LiveScience
