How do starfish eat?

Starfish

A starfish’s mouth, underneath its flat body, leads directly into a large, bag-like stomach. The starfish can push its stomach out through its mouth.  Starfish like to eat clams and oysters.  Encircling a clam with its powerful arms, the starfish attaches its sucker-like tube feet to the clam’s shell.

With ever-increasing force, it pulls the two halves of the shell apart.  Then, the starfish pushes out its stomach and digests the food.  When the starfish has completed its meal, it pulls back its stomach, and leaves only an empty clam shell behind.–Dick Rogers

Why does a camel have a hump?

Camel

The camel’s best known feature is the hump on its back.  The camel’s hump is mostly fat that provides nourishment when food is hard to find.  When a camel goes a long time without food, its hump shrinks.  After it has eaten and rested, its hump becomes plump and firm again.

People once believed that a camel stores water in its hump.  Now we know that a camel simply conserves its body moisture, rather storing an extra water supply.  It can travel for days without food or water because of its fatty hump and its efficient water conservation. – Dick Rogers
