Ever seen a shark poke its tongue out?
Baby Port Jackson sharks move from where they hatch to safe nursery areas for the first years of their lives, including in Sydney Harbour. Remarkably, small sharks that hatch around Cabbage Tree Bay will find their way into the harbour. They spend the first few years of their lives in these areas before they are large enough to migrate along with the adult population to deeper waters.
These small sharks are adorable and extremely photogenic. While sharks dont have a tongue, one cheeky baby seemingly poked a tongue out at me! Sharks do have a structure on the floor of their mouths called a 'basihyal'. It's usually unmovable but some movement may be possible in young PJs. (thanks to Prof. Bill Gladstone for his knowledge on this, and Bill and Adam for being buddies on the dive)
I've been unscientific in attributing emotions to the sharks in some images!
