Do insects have bones?

Insect

If you could look inside an insect’s body, you wouldn’t see any bones. But insects do have skeletons!  Insects differ from creatures with back-bones, such as humans, horses, dogs and fishes.  These animals have hard skeletons inside their bodies. Your skeleton is made of bone, and the rest of your body is shaped around it.

An insect’s skeleton though, is a tough outer shell.  It provides support and protection for the insect’s soft insides.  Some insects, especially beetles have hard, heavy skeletons.  Others, such as butterflies have light, thin skeleton. – Dick Rogers

How does coral grow?

Coral

Beneath the surface of the sea lie coral formations of many shapes and colors.  The formations may look like branching trees tinted green or lavender, lacy sea fans, or even like tiny organ pipes.  Coral is formed by millions of tiny sea animals called “coral polyps.”  Coral polyps look much like little flowers.

They wave food into their mouths with a circle of tiny tentacles.  Young coral polyps attach themselves to older ones and build limy, cup-like skeletons around their soft bodies.  When the polyps die, their hard skeletons remain as part of the growing coral formations. – Dick Rogers
