Why are these animals so muscular? 🤯😱💪 #animals #animalfacts #shorts

These animals may look like they never leave the gym, but the real reason is a genetic condition called myostatin deficiency. Myostatin is a protein that tells the body to stop building muscle once it has enough. However, in some animals, the gene that controls this process mutates into what’s often called the “Hercules gene,” removing the body’s natural muscle limit. As a result, these creatures don’t need to hit the gym or train day and night to bulk up. Fortunately, this mutation doesn’t cause any health problems, and they can live a healthy life.
