玳瑁海龟啃食坚硬的珊瑚礁，罕见的进食行为

bill sea turtle (Eretmochelys imbricata) bites directly into the hard reef wall, jaw and beak visible in close up detail against the coral substrate. Hawksbills are sponge specialists, and this feeding action likely targets encrusting sponge or invertebrate growth wedged within the rock, a diet that makes them important regulators of reef sponge competition. 4K, wide angle, vertical close up, scuba diver POV.
