Where can you get up close and personal with a colossal squid, an enormous sea monster from the deep sea? You might want to pay a visit to Te Papa, New Zealand’s national museum, which is home to the world’s only preserved complete colossal squid specimen. This type of squid was discovered in the Antarctic, and is the heaviest invertebrate in the world, with lengths up to 20 feet and weighing up to a thousand pounds.
