Tomtate
Haemulon aurolineatumAlso known as Tomtate Grunt, Yellow Grunt, Redmouth Grunt
Tomtates form dense, shimmering aggregations above shallow patch reefs and shipwrecks by day, drifting lazily within the surge. When dusk arrives, schools disperse into adjacent seagrass beds and open sand flats to hunt small invertebrates under cover of darkness. Like their relatives, they produce audible grunting sounds by grinding their pharyngeal teeth, which their swim bladders amplify during territorial disputes.
