When a predator like the barber slug comes by to clip off its tentacles, the anemone retreats quickly down the tube--sometimes pulling the slug in with it. Luckily an anemone's tentacles grow back after an attack.
Many of the seven species of the burrowing anemone have tentacles that fluoresce, absorbing ultraviolet light and shining it back as visible light.
Used the D-700 Nikon camera and the 24-120mm Nikkor lens. No flash used.
