Colossal Squid (Mesonychoteuthis hamiltoni)

The photo unavoidably foreshortens the squid. I put a water bottle at the far end to try and give it scale but it doesn't really work. This specimen is the largest Colossal Squid ever caught, and is the only one on display anywhere in the world (according to the signage). It is an immature female, caught in 2007, and measures 4.5m in total length and weighs 500kg. The tentacles are 2.1m long.

To show how the photos squash the apparent length down, the photo taken from the other end shows how large the body is:

Really interesting display actually and gives a greater impression of size IMO than in a vertically positioned tank.
