Alternate Common Names:
leaf fish, paper fish

Family Name:
SCORPAENIDAE
Click Name for Family Profile

Size:
10 cm (3.9 inches)

Distribution:
East Africa to the Galapagos Islands, north to Ryukus and south to New South Wales, Australia.

Habitat:
This species occurs at depths of less than 1 to over 134 m (3.3 to 442 feet) on reef flats, reef channels, fore reef slopes or on lagoon reefs, in areas protected from strong water movement.

Distinguishing Characteristics:
This species gets its name from its unusual form. With its laterally compressed body and high dorsal fin it resembles a leaf or macroalgae frond. It also mimics bits of plant debris by rocking back and forth or swaying from side-to-side. The overall coloration of this species can be black, maroon, red, brown, tan, bright yellow or white, with dark or light mottling. I have seen photos of a pair of bicolored specimens from the Fijian Islands; they were orange overall with bright yellow backs and dorsal fins. The coloration can change slightly as a result of shedding of the cuticle, which is quite common in this fish, or if they are moved from a light to darker background, or vice-versa. Small juveniles, which are rarely encountered in the aquarium trade, are nearly transparent.
