Found across tropical and temperate oceans worldwide, the Blue Sea Dragon is a tiny nudibranch that floats upside down on the surface of the water, carried by wind and currents. Don’t let its size fool you though — it feeds on some of the ocean’s most venomous creatures, including the Portuguese Man O’ War!

 

The Blue Sea Dragon actually stores its venomous prey's stinging cells in the tips of its finger-like cerata, concentrating them into an even more potent sting!
