Why does not a spider get caught in its own web?

Spider 

Spiders build their webs to trap flies and other insects for food.  An insect is unable to escape once it has become caught in the spider’s web.  The more the insect struggles, the more it becomes entangled in the sticky threads. A spider’s silk is strong enough that most insects cannot break through it.

A web-spinning spider does not become caught in its own web.  When walking across the web, it grasps the silk threads with special hooked claw on each foot.  The spider also secretes an oily liquid onto its legs and feet that prevent the sticky silk from sticking to its body. – Dick Rogers

How does a frog catch its food?

Frog

All summer long, the little frog squats, motionless, on the bank of a quiet pond or brook and watches for passing insects.

If a fly or cricket passes within reach, the frog’s long tongue will snap out like a flickering ship, so fast that you can scarcely follow the action.  The insect is caught on the sticky tip.  Just as quick as the frog flips its tongue back into its mouth.

The frog’s tongue is fastened at the front of its mouth, not the back, so that it can be flipped out a long way.  The frog’s mouth is equipped with feeble, practically useless teeth,  which are present only in the upper jaw.  So it must live mostly on small creatures that it can swallow in one gulp.

Frogs also eat earthworms, spiders and winnows that they catch in the water.  Toads capture their food in much the same way as frogs do.

Frogs and toads help man by sailing many harmful insects to be found in gardens and on farms.  – Dick Rogers
