We once read that there's apparently more known about outer space than there is about the sea. While this might have been a complete lie it managed to terrify and excite us in equal measures.
These pictures from Alexander Semenov have proved our feelings right on both counts. Working for the White Sea Biological Station, he captured a stunning variety of underwater critters while down there.
We can thank him for educating us and also for providing a rich variety of characters for our forthcoming nightmares.
While being interviewed about the Avatar sequel, James Cameron claimed that it will be set underwater and these pictures suggest that it might be a sneaky way to reduce the budget. Who needs CGI when you have real aliens like these?
