Snorkel with Sea Dragons: Australia
One of the most unusual creatures of the sea is found only off the coasts of southern Australia. Not quite a sea horse and not quite a fish, the mysterious sea dragon—which can grow up to 18 inches long—was named for its resemblance to the mythical creature and often escapes perception by the human eye. Squint hard—they’re often mistaken for seaweed swaying in the undertow, thanks to their leafy camouflage.
