There are 150 different species of hard corals in the waters surrounding Low Isles, although these are dominated by 15 species of soft corals. If you look closely, the feathery tentacles of soft corals can often be seen collecting tiny food particles from the water around them.
Living amongst the corals is a large variety of fish, molluscs, sea cucumbers and other animals. Colourful blue, green and purple parrotfish are a common sight as well as angelfish, damselfish, anenomefish or clownfish, trevally, rabbitfish, sweetlip, moon wrasse and fusilleers, just to name a few!
At least seven species of seagrasses grow on the intertidal sandflats of Low Isles, providing a home and food for such animals as sea cucumbers, the attractive spidershell, as well as rays, green turtles and dugongs.
