The newest comic by Buzz Hoot Roar, “We Got the Beat,” explains the correlation between heartbeat, metabolism, and life span, and illustrates the heartbeats of animals over a period of ten seconds. The blue whale’s heart only beats once every ten seconds, but the hearts of smaller animals like the shrew and hummingbird beat many, many times that amount. Check out the full comic on Buzz Hoot Roar.
