How does an octopus eat?

The octopus dwells on the ocean bottom, where it crawls about on its long, flexible tentacles.  It searches in every crevice for its favorite foods—crabs, lobsters, and shellfish.

An octopus’s tentacles are lined with cup-like suckers that enable it to grab and hold tightly to anything it catches.  The octopus then tears apart its prey with its strong parrot-like beak.

Some octopuses can inject a poison with their bite.  This poison is useful to the octopus in getting its food.  For instance, it can render a crab helpless, and thus easy for the octopus to capture and eat. –Dick Rogers

What are the whiskers for on an animal’s face?

Whiskers

The whiskers on an animal’s face are organs of touch.  They help the animal sense what going on around it.  Scientists call whiskers vibrissae (vi-BRIS-see). These long, sensitive hairs are most helpful to animals that prowl about in dark places.

A cat’s whiskers brush against objects the cat might not see as it hunts at night.  Whiskers help some animals find food.  The whiskers on a seal’s face are helpful in detecting fish in the dark or cloudy water.  And the thick whiskers on a walrus’s upper lip help it to feel for clams in the ocean bottom.–Dick Rogers
