The most unusual animal in Bristol Zoo

A description of the most unusual animal found in Bristol Zoo (established 1836). H/T Jason.

This reminds me of going to a nature reserve as a young child on a school excursion and learning about the various animals found locally. At the end of the exhibit was a wooden box with a trapdoor in the lid and a sign next to it saying something like, "The world's most dangerous animal". When you opened the trapdoor, you saw this.
