Picture a squid.
Now picture it really, really big. Colossal, even.
That’s a colossal squid! They have the largest eyes of any creature on earth. Mum thinks it’s so they can see at the bottom of the ocean, where it’s very dark. I think it’s so they can wear the biggest sunglasses ever and be the coolest creature in the ocean (that’s a little colossal squid humour…it’s probably the seeing-in-the-dark thing).
