Vedclass · Answer

(B) Tuna fish are known for being $warm-blooded$ (endothermic) but they are $poikilothermic$ in the sense that their body temperature can fluctuate to some extent depending on the environment, though they maintain high metabolic rates. However, the primary reason they are rarely found in tropical waters is that they are adapted to cold, nutrient-rich waters. They are $warm-blooded$ (endothermic) animals that maintain a high body temperature, and tropical waters are too warm for them to efficiently dissipate their metabolic heat, leading to thermal stress. Thus, they are $warm-blooded$ $poikilothermic$ animals.
