One of the more common fish seen at many Sydney divesites is the Eastern Blue Wrasse (commonly called a blue groper).
At Oak Park, near Cronulla, these fish are so friendly that they will swim right up to divers. This one was actually getting in the way of my photos, so I decided to make close up images of its features.
The Eastern Blue Wrasse is a protected species in NSW. Once quite threatened, their nature makes them easy targets for spearfishers.
