Sea Devils are one of my favorite Doctor Who villains, and one of my very favorite episodes. An underwater offshoot of the Silurians, the Sea Devils look so bored and so completely fed up with the Doctor’s and humanity’s bullshit. Plus their clothing is a very convincing see through fishnet, so they’re very fashionable turtles.

 

They were seen in The Sea Devils, and have made cameos in various other episodes.
