Polycentropsis abbreviata
The African leaf fish really does resemble a leaf - a camouflage used to outwit 
its enemies. Its deformable mouth means that it can swallow prey measuring up to 
half its own size. There are several related species; one of them, which belongs 
to the genus Monocirrhus, swims at an oblique angle, head down, and has a small 
barbel on its lower jaw. Size: 6-8 cm.
