Which animal has the largest heart?
When we think of big hearts, we usually think of those who are kind and compassionate. However, in the animal kingdom, having a big heart is a physical attribute. The animal with the largest heart is the blue whale.
The blue whale, which is also the largest animal on Earth, can weigh over 200 tons and can reach lengths of up to 100 feet. Its heart alone can weigh over 1,000 pounds, and it's so big that a human could swim through its arteries.
The blue whale's heart is a vital organ that helps circulate blood throughout its enormous body. With such a massive size, the blue whale needs a heart that can pump blood efficiently, and its heart does just that, beating only 5-6 times per minute, compared to a human heart, which beats about 60-100 times per minute.
