At 1 6ft, Big Bertha couldn't help but make a big entrance as she arrived at London Zoo. The giant Burmese Python was taken into her new home for the first time by a team of five zookeepers. The snake - which weighs approximately 80 kilograms - had been held in the veterinary hospital where she was held in quarantine after her arrival. Big Bertha's new home is the Reptile House at the zoo which featured in the first Harry Potter film - Harry Potter and the Philosopher's Stone. The wizard released a giant Burmese Python - like Bertha - from her glass enclosure in the reptile house after speaking to it in parseltongue. The scene was filmed at the zoo in 2001. DM
