Rusty Blenny

The Rusty Blenny (Parablennius sanguinolentus) is a charming little fish frequently encountered by snorkellers and shallow-water divers exploring rocky coastlines. While not a showstopper in terms of size (typically around 14cm, but occasionally reaching 20cm), its vibrant colours and bold personality make it a memorable sighting. These blennies are masters of camouflage, blending seamlessly with the algae-covered rocks they call home. Keep an eye out in the shallows, particularly amongst dense seaweed or near tide pools. They are often spotted sunning themselves on exposed rocks, darting back into the water when approached. Their herbivorous diet means they are always on the lookout for tasty algae, and you might be lucky enough to witness them grazing. While they may not be as flashy as some reef inhabitants, Rusty Blennies possess a unique charm that endears them to those who take the time to observe them. Their inquisitive nature and territorial displays make them a captivating subject for underwater photography and observation. Because they live in such shallow water, they are a fantastic species to spot even while snorkeling!
