photos by matt smith from the Illawarra coast in new south wales of bluebottles, violet snails and blue dragons. despite its resemblance to the jellyfish, the bluebottle is more closely related to coral. known as a zooid, the bluebottle (or portugese man of war)

for their part, the violet snails also feed on the bluebottles.

the blue dragon — a type of nudibranch, here no larger than a thumbnail, with its own potent sting — is able to eat the nematocysts (stinging cells) of the bluebottle without discharging them and internally relocate them to the tips of each one of the fingers you can see in the pictures.
