A pleasant afternoon of swimming in the backyard of a New South Wales home turned into a horrific event this week after a man said his 5-year-old son was attacked by a massive python.His 5-year-old son, Beau Blake, had gotten out of the water and was walking alongside the pool's edge next to the garden when the incident occurred.All of a sudden, Blake said, he saw the snake emerge, and the next thing he knew, the snake was "completely wrapped around" his son's leg and they were spiraling into the pool.It's unclear what type of python attacked the boy, but there are 15 species of python on the continent, according to the organization Backyard Buddies.The family ended up releasing the snake shortly after its attack on the child, but even after that ordeal, Blake said "the naughty thing" didn't slither away very far."
