Amazon leaf fish

Description:

An oval fish with a large mouth with a pointed lower jaw. The coloration can vary depending on the environment, they are usually orange-yellow to brown with various markings giving this species the appearance of a dead leaf. A transverse line runs through the eye to the belly, while another runs from the mouth, through the eye and to the caudal fin. The third line runs from the eye to first rays of the dorsal fin. The anal and dorsal fins are long and edged with light colored spines, also adding to the camouflage of a dead leaf.
