The Banded Sea perch is usually seen showing their muscles off by perching on their pectoral and ventral fins. They have four well-define black bands and can become quite a red in colouring.
For years we thought that the Bearded Cod was actually a catfish. They hide in the dark, under ledges just like catfish and they even have whiskers like catfish. But it's just one whisker and one whisker doesn't make a catfish.
Leatherjackets are one of the most common species in Sydney. They come in just about every colour, shape and size. Most have amazing colour changing powers. The only one which doesn't seem to be able to change its colour is the Black Reef Leatherjacket.
Blue gropers usually aren’t blue, they’re brown and they're not even gropers, they’re actually a type of wrasse.
All Goatfish have fleshy barbels on their chin that give them a bit of a goatee look. They use their 'goatee' to dig in the sand and detect their next meal - a very useful 'goatee' indeed. The most common goatfish in Sydney is the Blue Striped Goatfish, not to be confused with the almost identical Blue Spotted Goatfish.
The Sabretoothed Tiger was once man's most feared predator - the scariest creature on the planet. Fortunately Sabretoothed Blenny aren't really in the same league.
Bullseyes seem to pop up all over Sydney. They are usually lurking in dark caves and under ledges and it's only when you shine your light in, that you see their tiny big eyes staring back at you.
Some Leatherjackets are beautifully designed and very rare in Sydney. They can usually be seen hanging around piers as they are a hungry mob, and they like overhanging ledges. Probably because fisherman are quite fond of them.
Crested Morwong may have an odd name, but then again they're a bit of an odd fish with their yellow and black stripes and strange looking crest.
Let’s be honest, frogfish aren’t pretty – they have a face that only a mother could love. There are plenty of frogfish in Sydney Harbour but fortunately they rarely dare to be seen out in public. They spend their days, hiding from view, in dark little holes.
