). Has prickly papillae instead of scales. Dorsal fin high, 3rd or 4th spine longest; suborbital ridge without spines or with lump at head of ridge; preopercle with 2 indistinct spines only; body extremely compressed; soft dorsal fin attached to the caudal fin; coloration is variable, from nearly all yellow to red, brown or nearly black and variously mottled with darker pigment (Ref.
10482
).
Inhabits reef flats, outer reef slopes, current-swept channels, and rarely on lagoon reefs (Ref.
1602
). Benthic (Ref.
58302
). Solitary and usually immobile among algae or seagrass but effects hip movements resembling that of a leaf falling down from a tree. Molts twice a month with the skin breaking off first in the head region. Has the habit of mimicking a dead leaf by swaying from side to side (Ref.
37816
). Feeds on small crustaceans and fishes (Ref.
9710
); also feeds on larvae (Ref.
5503
). Venomous spines.
