[Press Release] Shortfin mako sharks show enhanced thermoregulation abilities during deep dives

Release Summary

We show that regionally endothermic shortfin mako sharks have enhanced thermoregulatory ability with an order higher warming rate than cooling rate during repeated dives, likely optimizing foraging efficiency. This ability, only comparable to bigeye tuna and swordfish in teleosts, represents the key adaptive significance of regional endothermy in fishes.
