Tuna is an obligate ram ventilator and relies on a specialized respiratory system that propels water over its gills as it swims. This system enables tuna to oxygenate blood during long-distance migrations. Consequently, its muscular metabolism generates continuous heat, granting it the ability to regulate the body temperature.
