"Sea anemones and their symbiotic inhabitants are my favourite targets," says Savin. "A large anemone is like an apartment building with many different inhabitants establishing different relationships and relying on each other’s character. It's interesting to watch the same creatures day after day and I love to study them as they evolve. On this day I took dozens of shots of an anemone with different settings. Suddenly, as if by magic, a crab came out and sat right in the centre. I just had to press the button."
