So you can smell the trigonellin in your coffee?

But you would if you were a tiny mud crab, and that smell would be the scent of fear.

OK, when a blue crab eats, its body breaks down the food, kind of like how ours does during the digestion process.

You know, the time between when we eat our food and when what's left and not used by our bodies comes out the other end.

And when the blue crab goes to pee, those two chemicals tell the mud crabs what the blue crab had to eat.

And the warning signals become especially strong if the blue crab's last meal was mud crab.

The smell of fear.

Yep.
