Thereby Hangs A Tail?
Sanctuary Papers: Dose of Natural History and Science – When you think of an animal’s tail, you think of round, tube-like structures. But, seahorses have tails made of square skeleton segments hitched together that act as protective cages.
Illustration: Vinay A. Salvi.
Together these squares make stronger and better protected appendages than round ones. The reason is very simple; a square on coming in contact with a surface has more surface area pressed against it. This gives seahorses a better grip.
Each of these square segments is made up of four angular (90 degrees) pieces attached together.
