Dagger Devil

Imagine a giant 500 lb creature armed with a deadly eight-inch dagger-like barb capable of stabbing and injecting you with one of the most painful toxins in the animal kingdom...That's the unsettling, elusive ghost Cyril is after in Thailand. The giant freshwater stingray is possibly the biggest freshwater fish on the planet and Cyril has been called in by a team of researchers who need him to collect venom from stingrays in order to help develop an antidote. But for that he's going to have to get dangerously close to that vicious barb.
