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’.

Are snails blind?

Snails have very poor vision . 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.
