A new modeling approach reveals that mesothermic fish, such as certain sharks and tunas, expend approximately four times more energy than ectothermic fish of comparable size and conditions. This heightened energy expenditure is due to a scaling mismatch where heat production increases faster than heat loss as fish grow larger, leading to a persistent overheating problem. Consequently, these warm-bodied fish are already operating near their thermal balance limits, making them particularly vulnerable to further ocean warming and potentially leading to disproportionate population declines.
