True
The text asks which animal's heart beats only 9 times per minute, with options including a blue whale.
Infact verdict: True (86/100).
The claim that a blue whale's heart beats only 9 times per minute is generally accurate but slightly misleading. Evidence shows that a blue whale's heart can beat as few as 2 times per minute when diving and up to 37 times per minute when surfacing. However, it is commonly reported that the heart rate is between 5 to 10 beats per minute on average. Therefore, the claim is mostly true but oversimplified.
