This comparison reveals the true scale of hearts from dozens of species, using realistic models. Watch as the hearts grow from barely visible organs smaller than an ant to the enormous blue whale heart, which is large enough for a person to stand beside. By presenting every heart at the same scale, this video offers a fascinating look at the remarkable diversity of the animal kingdom and highlights how evolution has shaped one of the most important organs in every vertebrate.
