How Fast Is Yellowfin Tuna?

Yellowfin tuna swim at 76 km/h — warm-blooded, unusually for fish, which gives them their burst capability. They migrate thousands of kilometres annually without ever stopping; their body literally cannot rest, requiring constant motion to push water over their gills.

Yellowfin tuna are warm-blooded fish — a rare adaptation that lets their muscles work efficiently at burst speeds in cold deep water.
