Long term observations were made on the yellowhead jawfish utilizing an underwater video-acoustic system at Bimini, Bahamas. Both flight and aggressive responses were observed towards other fishes. Epinephelus striatus was observed to cover over burrows, Malacanthus plumieri to behave aggressively toward jawfish, and Halichoeres garnoti and H. bivittatus to behave aggressively and enter jawfish burrows. Of interactions observed with 27 species, large piscivores produced the strongest flight responses. Large non-piscivores produced milder responses and aggressive responses were directed only toward small fishes.
