Abstract

Despite ray-finned fishes representing the most species-rich group of vertebrates on earth, representatives from few fish families (mostly marine) have been observed using novel methods to manoeuvre objects to access prey. Specific behaviours include mouthing water jets or using fin beats to excavate prey from fine sediments, smashing prey on anvils, and pushing, flipping, lifting or carrying substrate (Jensen 2005; Brown 2012). There are no published records of these behaviours pertaining to any of the grunters (fishes of the family Terapontidae, distributed in the Indo-Pacific region and mostly inhabiting fresh waters in Australia and PapuaNew Guinea: Allen et al. 2002; Shelley et al. 2018).
