Why do humans need bones, if sharks don't? πππ . The difference is one of the beautiful examples of evolution and perfect habitat adaptation! π . Bones? Strong, but brittle and not very bendy. Cartilage? Squishy, but light and flexible. What it comes down to? Gravity β¬οΈ . If we, humans, were built out of cartilage we would simply collapse under the force of gravity. We need a stable bony frame to withstand the needs of living on land. ποΈ . Sharks on the other hand, don't have this problem. Light, flexible skeleton not only means they need to spend less energy on swimming, but also makes them quick, agile master predators we all love β€οΈ . π Follow @freshnsaltyeco to get a clue in the blue! . . . #freshnsalty #clueintheblue #oceandecade #cartilage #sharksareawesome #sharkeducation #protectthesharks #sharkfin #sharks #oceandecade #sharkeducation #sharksarefriends #sharksofinstagram #savethesharks #oceaneducation #marinewildlife #animaleducation #protecttheocean #oceanawareness #savetheseas #marinelifematters #savemarinelife #oceanconservancy #oceanminded #oceanconservation #sciart #oceanlovers #oceanlife #marinelife https://www.instagram.com/p/Cb7yc2ZvCWg/?utm_medium=tumblr
