Crown of Thorns

This beauty almost took my breath away, although it's a good thing there aren't many of them around here because they eat the coral. In a healthy ecosystem, they have their own predators. Harlequin shrimp, giant triton, and humphead wrasse prey on the adults, while anything that eats plankton preys on the juveniles. There is even a coral polyp (Pseudocorynactis - a type of anemone) that can eat the crown whole!
