Low tide exposes an interesting seascape......an underwater garden of sea urchin beds
Another walk out at the North West Point where the beach is usually strewn with sea urchin tests (skeletons). If you walk out into the water you will find many live sea urchins which are black and black with red. These sea creatures apparently come in many different colours.
Long-spined Sea Urchins tucked into holes in the rocks and the coral reef just below the water out at the North West Point
Sea Urchin bodies are covered with spiney shells....the spines are moveable.
The bottom side of a sea urchin has five teeth with which they eat algae. They are found in areas where there are lots of seagrass, seaweed and other foods.
Black moveable spines protect the sea urchin from predators
