What does the sailfish's need to reach high speeds imply about its metabolic rate and typical lifespan?

Answer

A high metabolic rate and a relatively short lifespan, perhaps only a few years.

The ability to reach 68 mph requires the fish to operate at an intense metabolic rate, rapidly burning fuel, which is associated with a relatively short lifespan compared to slower, long-lived marine inhabitants.
