According to my Taiwanese scientist friends, there is currently no significant population of Cane Toads in Taiwan, although the Japanese tried to introduce them on at least two separate occasions back in the day. Taiwan's climate and terrain could certainly support a population, and probably WILL in the future. But if you run a search for 海蟾蜍 (Cane Toads), you don't find any reference to any recent sightings in Taiwan, although I didn't look very hard and would be interested if someone could dredge one up. At any rate, that is NOT a Cane toad in the video being eaten by a L. rufozonatum and this is a thread for snakes, not toads.
Speaking of which...if anyone is interested in going out on a night hike to look for snakes (and other wildlife), shoot me a PM and I'd be happy to try to meet up. No equipment, experience or knowledge necessary - I've got a ton of hooks, headlamps and flashlights I can lend.
