Do snails lay eggs?
Snail egg fact #5:
Snails lay their eggs in interesting places
. Land snails often lay their eggs in the dirt. They prefer to dig a small hole in the dirt where they lay the eggs, safe from most predators. Marine snails often lay their eggs above the waterline near or on a rock where they can anchor the eggs.
Why don t snails have bones?
Most gastropod species consist of an outer shell
. Therefore, Snails too have a hard and non-bony outer shell. The skeletal system type of snails is referred to as the ‘Exoskeletal System’.

What happens if a snail loses its shell?
If this shell becomes significantly broken then
the snail will probably die
. Whilst snails can repair small cracks and holes in their shells, if the break is serious then they will struggle to survive as the shell not only provides protection but also prevents them from drying out.
Do snails have feelings?

. Even though they have a lens on their eye, they have no muscles to focus the images. They can sense light and dark and work out where the light source is. They cannot see colour.
Is a snail shell an exoskeleton?
Seashells are the exoskeletons of mollusks
such as snails, clams, oysters and many others. Such shells have three distinct layers and are composed mostly of calcium carbonate with only a small quantity of protein–no more than 2 percent. These shells, unlike typical animal structures, are not made up of cells.
Are snails arthropods?
Well, the short answer is
no
. They’re members of the animal kingdom, like bugs. But they’re in a different phylum altogether — the phylum Mollusca to be exact — unlike insects who are in the phylum Arthropoda.

. More specifically, they belong to the taxonomic class Gastropoda. Both slugs and snails can be found in most parts…
Which group of animals is invertebrates?

What are 5 invertebrate animals?
More than 90 percent of all living animal species are invertebrates. Worldwide in distribution, they include animals as diverse as
sea stars, sea urchins, earthworms, sponges, jellyfish, lobsters, crabs, insects, spiders, snails, clams, and squid
.
