Squirrel Appreciation Day is here so how about a shout out to the Squirrelfish?! This family (Holocentrinae ) of nocturnal reef dwellers are not only known for their large squirrel-like eyes, but also their ability to use their swim bladders to produce grunts and clicking sounds (aka staccato ) that allow them to communicate with each other. . 📸: Holocentrus rufus (Longspine Squirrelfish ) by @nickhobgood #SquirrelAppreciationDay #squirrel #Squirrelfish #fish #fishes #fishy #fisheye #eyes #bigeyes #fishfriends #ichthyology #yearofthereef #IYOR2018 #nocturnal #reefdweller #bioacoustics #communication #swimbladdar #grunt #click #staccato #marinebio #marinebiology #marine #ocean #science #research #funfacts #dyk
