On Sunday 10 September, the day before the snakebite management course began, we all made a trip southeast down the coast of Central Province to Hula, where we had been told the fishermen had collected some stonefish for AVRU.

Reef stonefish, Synanceia verrucosa, are the most venomous fish in the world. Their resemblance to lumps of coral is uncanny but they possess 13 enlarged dorsal spines that will inject and extremely painful and rapidly lethal venom deep into the foot of anyone who steps on one. In the event no stonefish had actually been caught and while the others relaxed, David and I went further along the coast, searching unsuccessfully for snakes. All we found where Eastern bicarinate four-fingered skinks (Carlia bicarinata) and Slender forest skinks (Sphenomorphus cf. fragilis).

A stonefish was delivered to Port Moresby the following day and Dave Williams extracted venom from it for Laura Griesman, a visiting American researcher working at AVRU on a Fulbright Scholarship. The fish was temprarily confined in a water-filled polystyrene box with a slit in the top through which Dave could ease a vacuum tube. When the rubber grommit of the tube was pushed over the venomous dorsal spine venom was drawn into the sterile tube... easy, and the process did not harm the stonefish.

Precision work!
