Dragon vs. Jelly

Blue Dragon

Buedragon2In the ocean lives a dragon

Who is luminously blue

And although she looks quite harmless

You will find it isn’t true

 

This Blue Dragon is a sea slug

Calmly floating on her back

While a Man-of-War approaches

And commences its attack

 

BlueDragonvsmanowar

Now it’s jelly versus dragon

Who lacks flames and cannot roast

But the sea slug wins the battle

And that jellyfish… is toast

 

And she swallows down the jelly

Gobbles up each stinging cell

Then she redistributes poison

In a way that suits her well

 

At the end of each frilled finger

Little Dragon packs a punch

As she uses jelly poison

To subdue her next sea lunch

The Blue Dragon, or Blue Glaucus, is a sea slug that can grow up to about 3 centimeters long. It spends its life floating along just under the surface of the water, upside down. It carries an air bubble inside that allows it to stay near the surface of the water. The Dragon’s blue underside cannot be seen well from above, protecting it from hungry, fishing birds. Its topside is silvery gray, which cannot be seen well from under the water and this protects it from hungry fish.

Some sea critters do manage to find this feisty delicacy and do try to eat it. They must get past its poison, however, for it protects itself well. When a blue dragon manages to beat and eat a Portuguese Man-of-War, it has the unique ability to swallow the stinging cells, or nematocysts, without harming itself. On the contrary, it uses these stinging cells to defend itself in the wild blue yonder.
