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.

The seahorse's tail boasts of a rare design comprising square segments, unlike the round tails sported by most other animals.

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.
