That snakey looks uncannily like one of the two I donated to Jack Corney at Isle of Wight Zoo at that time!! one of them had the '!'shaped mark (dot then dash)on the head. The Zoo would also collect venom from its poisonous snakes for anti-venom. Jack Corney was in the Guiness book of records at one point for surviving the most number of snake bites. The Zoo also used to walk tiger cubs along sandown beach in the winter Luckily we were never up that early in the day!
