Not so long ago, Santa went on a sailing trip!

This postcard, which he sent to his chief elf, Mr Likesalist, has a puzzle on it. Being such a busy elf, Mr Likesalist hasn't had time to work it out yet - perhaps you can do it for him?

Look closely at the pictures and names of some of the magical sea-creatures Santa has come across. Can you guess which names belong to which creatures by looking at the pictures of them?
