Great white sharks maintain warmer body temperatures than surrounding seawater and face the risk of potentially fatal overheating as oceans warm due to climate change. Warm-bodied fish such as great white sharks burn up to four times more energy than cold-blooded fish and face a "double jeopardy" of warming waters and declining food supplies. As oceans warm, these species likely face an increasing risk of overheating, resulting in reduced suitable habitat and enforced relocation toward the poles.
