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

How does a spider spin its silk?

Spider

A spider spins its silk by releasing a liquid through its spinnerets.  The liquid hardens into a silk thread as soon as it touches the air.

Spiders are small, eight-legged animals that are best known for the silken webs they spin.

Spiders have spinning organs called spinnerets on the underside of their stomachs.  Through the spinnerets, spiders release a liquid that hardens to silk as soon as it touches the air.

The spider cannot force the silk from its silk glands in a stream.  When it is spinning a web it pulls the silk from the spinnerets with a hind leg.

Spiders use their silk in many ways.  Some spin webs to catch insects for fond.  They also line their retreats and nests with it.

Most spiders enclose their eggs in a protective eggs sac, or cocoon of silk.  The newly hatched spider lings may migrate to new homes by spinning silken, gossamer threads carried by the wind.

The spider traits a dragline wherever, it goes.  It can swing down to the ground from high places or swing out of reach of any enemy.  – Dick Rogers

How do the black widow spider get its name?

Black-widow-spider

The black widow spider gets its name because the larger female sometimes kills and eats the male if he does not escape immediately after mating; but she is quite as likely to live on friendly terms with her mate.

The female black widow is one of the few spiders in the United States dangerous to humans.  It’s painful bite contains a poison that can make a person very ill, but a black widow bite seldom kills anyone if the bite is properly treated by a doctor.

Fortunately, the black widow is easy to recognize and can easily be avoided.  It has a shiny black body about the size of a large pea, and usually has a scarlet patch shaped like an hourglass on its stomach.

The black widow weaves hopeless webs under logs and in dark nooks in the corners of barns and sheds.  The female spider places her eggs in round silken cocoons.  Each cocoon may contain as many as 700 eggs. – Dick Rogers

How does a slug move?

Slug

A slug is a cautious creature something like a snail, but without a shell.  Slugs are famous for the “sluggish” pace  at which they travel.  You’ve probably seen a slug creeping along on a part of its body that seems to be its stomach.

Actually the bottom part of the slug’s body is really its “foot”.  The muscles in the slug’s foot move in a wavelike motion that causes the slug to glide slowly along.  It leaves a glistening train of slim behind it as it crawls.

This serves as a slippery path to help the slug slide along more easily.  The goo also protects the slug’s body as it crawls over sharp rocks and twigs.

Slugs live in moist places.  They are often found under logs and stones.  Slugs are often garden pests because they eat plants.  To help them eat, the tongue of a slug has hundreds of tiny “teeth”  with which if files away bits of food. – Dick Rogers

 

 

 

What is a starfish?

Starfish

A starfish is a star-shaped animal that lives on the bottom of the sea in bays and shallow water.  Starfish eat clams and other shellfish by pulling the shells apart and pushing their stomach into the shells to digest the food.

Starfish have a peculiar way of eating.  The common starfish feeds mostly on shellfish, it especially likes to eat clams, oysters, and mussels.

To open a clam shell, the starfish wraps its arms around it.  Under each arm are rows of tube like feet that stick to the shell like suction cups.  The starfish then pulls the two section of the clam’s shell assist with its powerful arms.

A starfish’s mouth is under its body.  As soon as a starfish has pulled open the clam, it opens its mouth, turns it stomach inside out and pushes it inside the clam’s shell and digests the clam’s soft body.

Once the meat is finished, the starfish pulls back its stomach, leaving only an empty clam shell behind.  Most starfish have five arms, but some have seven arms or more.  If a starfish loose an arm, it can grow another. – Dick Rogers
