Snakelocks anemone - Anemonia viridis

The snakelocks anemone is a sea anemone found in the eastern Atlantic Ocean to the Mediterranean Sea.

The tentacles of anemones in deep or murky water can be a grey colour, but are otherwise usually a deep green colour with purple tips due to the presence of symbiotic algae within the tentacles that use sunlight as an energy source. Since the anemones benefit from this. they prefer brightly lit shallow waters. On average the snakelock anemone is 8 cm wide.
