BLASTERMIND Something Fishy

This week’s Blastermind is like peering into the strangest aquarium ever created. Underwater aliens, amphibious races and murderous mer-beasts are the theme of the quiz thois time round. But we know you’re all dab hands at Blastermind by now, so you should have have no problem plaice-ing the fins in these pictures without any floundering.

Just identify the TV shows, films or games the following images come from. It’s as simple as sprat!

Usual request: Please don’t put answers in the comments section below (though feel free to use it to boast/bemoan how well/badly you’re doing) but the folks on this thread are quite happy for you to post and discuss answers if you follow the golden rule of only posting answers in invisible text (if you don’t know how ask somebody there – they’re very friendly).
