Ask Finn

Unmistakable calcified macroalgae resembling an old-fashioned shaving brush — white stalk topped with a tuft of fine green filaments. Anchors in sandbed. Relatively short-lived (months to a year); when it dies it releases calcium into the water. An endearing curiosity for Caribbean reef displays.
