What is the weirdest animal you have ever seen?

Tweet

The diversity of animals in the world is just amazing. But out of all those you have seen which do you think is the weirdest and why? I think for me it would be the Axoloti. They just look so strange and alien-like to me. You can see a photo here: http://www.axolotl.org/images/animals/bob_28_may_2000.jpg There are probably so many more weird animals out there though. Whats your thoughts?
