Demonstrate that ocean warming compromises large oceanic fish
A study published in Science warns that large oceanic fish such as tuna and great white sharks face an increasing risk of overheating due to rising sea temperatures, which could affect their survival and cause population collapses.

TL;DR
- Large mesothermic ocean fish like tuna and great white sharks face increased risk from warming seas.
- Rising ocean temperatures create a high energy demand and risk of overheating for these species.
- As mesothermic fish grow, they generate heat faster than they can dissipate it, causing a metabolic imbalance.
- The study can predict which species are most vulnerable to ocean warming, aiding conservation efforts.
- The findings may explain past species extinctions, such as the megalodon, due to a combination of high energy needs, poor heat dissipation, and changing ocean conditions.
