Imagine a vibrant flower blooming on the reef, but instead of petals, it has stinging tentacles! That's a sea anemone, a fascinating invertebrate commonly encountered by divers and snorkellers in shallow waters. These colourful creatures come in various sizes and forms, often resembling a soft, swaying pom-pom attached to a rock or coral. Divers typically spot them nestled in crevices, clinging to reef walls, or even attached to the seabed. What makes them truly special is their symbiotic relationship with other marine life, like clownfish, who find refuge amongst their stinging tentacles. Observing this interaction is a highlight for many underwater explorers!
Sea anemones are easily recognized by their flower-like appearance, with a central disc surrounded by numerous tentacles. Their colour varies widely, from bright greens and reds to more muted browns and purples. The tentacles themselves can be smooth or textured, and some species display distinctive banding patterns. Look for their characteristic swaying motion in the current, and note their attachment to rocks, coral, or the seabed.
Safety Warning
Stinging cells can cause mild skin irritation. Avoid touching.
