The name leaf fish is applied specifically to Monocirrhus polyacanthus, a South American species that is known for its close resemblance in both appearance and swimming behaviour to a dead, drifting leaf (see photo). This species is about 7.5 cm (3 inches) long and is coloured a mottled brown; it has serrated dorsal and anal fins that resemble the saw edges of leaves and a chin barbel that looks like a broken leaf stem.
