Yes, it’s rather funny, really, that next to no-one realised the snake that Harry set free in Philosopher’s Stone (USA: Sorcerer's Stone) turned out to be Voldemort’s final Horcrux, Nagini.
UPDATE: The above revelation of JK Rowling, that I got from different websites, forums, and Facebook accounts, is not true. I repeat, Nagini is not the Zoo Snake.
According to Rowling's Army tweet:
Nagini is NOT the snake Harry let loose in Philosopher's Stone. That snake was headed to Brazil and Nagini was probably found in Albania
