The Web of Life (15-6-5) The Scent of Food

 The Scent of Food

For many animals, vision is less important than their sense of smell. Because predators often rely on odors to find their prey, even visually camouflaged animals may stick out like a sore thumb if they smell strongly of “food.” ~ Australian marine biologist Rohan Brooker

Orange-spotted filefish exclusively feed on a specific coral. The coral is not just chow. Filefish absorb the coral’s chemical composition and thereby smell like their food. The chemical crypsis is good enough to fool predators on the reef which rely upon scent as well as sight to suss their prey.
