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 was a unicorn?

Unicorn

Old Greek and Roman myths tell of a strange beast with the head and body of a horse, the tail of a lion, and the beard of a goat.  It was called a “unicorn.”  A unicorn had a single long, twisted horn sticking out of its forehead.  Those who drank from a cup made of a unicorn’s horn were said to be protected from poison.

The idea of unicorns may have started with the tales told by early travelers—tales which probably described the rhinoceros or the oryx, a long-horned antelope. The tales grew more marvelous each time they were told.  – Dick Rogers

How do bees sting?

A worker honeybee can only sting once in its life.

Most bees depend on their stingers, or stings, only as a means of self-defense and to protect the bee colony’s store of honey from robber bees and bears, as well as people.

Bee

A bee’s sting causes sudden pain and swelling.  You may know something about that already.

The stinger of a worker is located at the tail end of its body.  It has little barbs that turn inward.

So, when the bee sticks it into your skin, the barbs hold so tightly that the bee cannot pull it out.  The bee must tear itself away, leaving part of its body behind the stinger.

The bee dies soon after losing its stinger continue to pump the stinging fluid into the wound even after the bees has flown away.

If you are stung, gently scrape the stinger off immediately.  This reduces the amount of poison that enters the wound.

There are many kinds of bees, and many of them don’t sting at all.

Bumblebees and wasps can use their stingers over and over. – Dick Rogers

What are jellyfish?

Jellyfish

Jellyfish are unusual sea animals that have jellylike bodies and stinging tentacles, with which they capture their food.  The jellyfish is among the strangest of sea creatures.

It is not even a fish, but a very simple kind of sea animal that has no skeleton.  The main pair of the jellyfish’s body looks like an umbrella, and it is made up of two thin layers of tissue with jellylike materials between them.

Around the rim of the umbrella are usually a number of simple eyes, and in the center of the body underneath is the mouth.

Hanging down from the edge are string like tentacles, armed with batteries of stinging cells filled with paralyzing poison.

If a small bumps into the jellyfish’s tentacles, it gets stung and captured for food. If you touch these tentacles, you may get stung, too!

A jellyfish swims by folding and unfolding its body—much like closing an umbrella.  Mostly, it floats along with the current.  Some jellyfish are no larger than a pea.  Other may be two feet or more in diameter. – Dick Rogers
