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) is a colonial animal composed of many highly specialized and physiologically integrated individual organisms incapable of independent survival.
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.
for their part, the violet snails also feed on the bluebottles.
notes matt, “despite their potentially dangerous sting, the bluebottle is an amazingly beautiful creature. with strong winds, hundreds of these cnidaria are blown into the bays around my home town and trapped overnight.”
this allows him to capture the above shots, which he creates with use of a fluorescent tube in his strobe light and a homemade waterproof lens dome.
