Another example of the many rather freakish snakes that Thailand houses is the aptly named Tentacled Snake, with its give-away feature of a twin pair of "tentacles" attached to its snout. For the longest of time, no one could say for sure what these tentacles were for, but latest studies may suggest them to be highly mechanosensory detectors for sensing prey in murky water. Another fascinating feature is the way it hunts its main prey: Triggering the Mauthner Neuron of fish which reacts to pressure waves (which, in fish, causes a reflex to quickly move away), the snake basically fools its prey, leading it right into its mouth. Being rear-fangend, it possesses a mild venom that humans don't have to fear - the same can't be said for fish, though.

Personal anecdote: Years back at a local snake farm in Thailand, the snake keepers were so impressed by my enthusiasm and absolute lack of fear regarding snakes (i was a little kid back then and most kids would do after their parents and naturally go all "eewww!" when exposed to these things) that one of them would lead me to a water jar, grab a pair of these Tentacled Snakes and put them right into my hand. I was so in love that i'd keep them for God knows how long. The snake keeper wanted to give them to me as a present, "take them!" And i so would have done that - if it wasn't for my mother. Who said NO.
