A video of a wild Asian elephant (Elephas maximus) having a bad day. He is male, fully grown but still young as denoted by his small tusks and is probably coming into musth as he is assumed to be following a herd that has become very active in the area. Note the severe damage to his right ear flap.
Without a doubt asian elephants are probably the most dangerous mammal in Thailand's forests. The common misconception of a gentle animal is a result of mankind's interaction with the wild elephant's tamed brethren. The wild elephant is an extremely dangerous animal and to be avoided at all costs if in the forest.
