The Blue Dragon, or Blue Angel, is a species of nudibranch. Like all
nudibranches, the Blue Dragon is a hermaphrodite. They can grow up to
3 cm in length. Despite their tiny size, they are a voracious predator,
preying on the venomous Portugese Man O’war. They are immune to the
poison and actually devour the whole victim, taking the poison into
their own system. This then becomes concentrated within this tiny
critter and makes them even more venomous than that which they consume.
