The Blue Dragon floats upside down on the sea’s surface, carried by the wind and waves, thanks to a little air bubble in its belly.

Drifting just below the surface, it creeps up on venomous prey—wrapped in mucus armor to avoid getting stung itself.

Instead of making its own toxins, it cleverly steals stinging cells from creatures like the Portuguese man-o-war—and saves them for later.

When threatened, this sea slug unleashes all that stored venom in one go—often packing a sting more painful than its original victim.

These slugs are hermaphrodites—each one has both male and female organs. After mating, they lay strings of up to 16 tiny eggs.
