Flávio C. T. Lima and Gilberto N. Salvador. 2018. Fooled by a fish: seed camouflage by an Amazonian banjo catfish, Bunocephalus verrucosus (Siluriformes: Aspredinidae). aqua, Volume 23, Issue 4: pp. 137-145
Abstract
Seed camouflage (masquerade) by Bunocephalus verrucosus, an aspredinid catfish, is herein reported based on two observations of specimens that folded their caudal peduncle against the side of the body after being captured, in the region of Tefé, Central Amazon, Brazil. This is the second report of seed camouflage for aspredinid catfishes, the first being reported for Amaralia hypsiura. Types of camouflage among aspredinid catfishes are herein reported to range from masquerade, background matching, and disruptive coloration. Many seeds (mostly drupes) of the flooded forest may serve as potential models for Bunocephalus verrucosus across its range, particularly seeds of Chrysobalanaceae.

Too bad I was not able to find any pictures of the said seeds of Chrysobalanaceae.
