How do snails eat?

Snail Eating

The garden snail comes out mostly at night to feed on leaves and other plant food.  The snail’s mouth is under its head.  It has no chewing jaws.  To help it get its food, the snail’s mouth is equipped with a special tongue that is covered with hundreds of tiny teeth.

It is called the “radula” (RAJ-uh-luh).  The rasp-like radula shreds and scrapes bits of food into the snail’s mouth as the snail crawls along.  The snail finds its food with two pairs of tentacles on its head.  The shorter pair is used for smelling on the tip of each of the longer tentacles is an eye. – Dick Rogers

What is a periwinkle?

Periwinkle

In zoology, periwinkles are sea snails.  They are usually found living along rocky Atlantic seacoasts.

In zoology, “periwinkle” is the name for several kinds of small sea snails.

The best known is the common European periwinkle.  This little, drab-colored snail is easy to recognize by its thick, spiral shell with its sharp peak.

Periwinkles are a common sight along the rocky shores or New England and are usually found in great numbers clinging to wave washed rocks between high and low tide marks.

The periwinkle grows to be only about an inch long, but its tongue is several inches long and is equipped with hundreds of tiny “teeth” for scraping off tiny green plants called algae.

Despite their small size these very tiny snails are popular delicacy in Europe.  At one time they were an important source of food.

Women and children once made their livelihood by collecting thousands of these little animals from the rocky coasts of the British Isles.  – 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
