📊 The Resting Heart Rates of 15 Different Animals
🔸 A resting hummingbird's heart can beat up to 225 times per minute, while a blue whale's heart can beat as slowly as twice per minute. The animal kingdom's wide range of resting heart rates shows how size, activity levels, and environmental demands shape each animal's physiology.
🔸 This graphic shows the resting heart rate range of 15 animals in beats-per-minute (bpm) using data from Merck Veterinary Manual. Typically, smaller animals like rats, guinea pigs, and rabbits have higher resting heart rates compared to larger ones.
🔸 One reason for this is that smaller animals have higher metabolic rates per unit of body mass than larger animals. The metabolic rate is the rate at which a living thing consumes energy to maintain basic bodily functions while at rest. As a result, their hearts need to pump blood more frequently to deliver oxygen and nutrients to cells, leading to higher resting heart rates.
🔸 Larger animals' hearts have a greater stroke volume (the amount of blood pumped from the heart to the rest of the body) than smaller animals. This enables them to have a lower resting heart rate as each heartbeat pumps more blood to the rest of their body.
