How do you measure a snail shell?

In snails, the length is taken from the apex of the shell to the base of the aperture (mouth). The width should be taken at the widest part of the shell when the shell is oriented so that aperture faces the observer; the width is measured from the side of the body whorl to the outermost side of the aperture (mouth).

How thick is a snail shell?

Mean adult thickness varied between about 0.08 mm and 0.20 mm. These values are much lower than previously published values. The considerable variation within samples was related to shell size, periods of growth, and resorption of shell material during breeding.

What is the shape of snail shell?

There’s a great post up on The Atavism by David Winter where he explains why the shape of the snail’s shell is a logarithmic spiral.

Can a snail take its shell off?

Sadly more often than not the outcome is not good. Snails can usually only repair minor damage to their shells, the comforting tale that snails can ‘move’ to a spare empty shell is just a myth.

How do I know what kind of snail I have?

Firstly the number of whorls can help to determine between species. The profile of the whorls and their comparative size can often help, some snails are very ventricose, others very slender, some have a huge body whorl, others have more evenly increasing whorls.

How do you classify slugs?

The Class Gastropoda (in Phylum Mollusca) includes the groups pertaining to snails and slugs. The majority of gastropods have a single, usually spirally, coiled shell into which the body can be withdrawn.

How is a snail attached to its shell?

The body is attached to the shell either by one columellar muscle or by a series of muscles. Typical snails can withdraw the head and foot into the shell, but numerous species have shells so reduced in size as to be unable to contain the body; slugs, of course, have either an internal shell vestige or no shell at all.

What is under a snails shell?

The mantle is a fold of skin that surrounds the snail’s internal organs. Under their shell, land snails have organs and systems just like humans do. The animal’s internal organs, which include a digestive gland, lung, heart and reproductive organs, are located within the mantle cavity, inside the shell of the animal.

Why are there empty snail shells?

Snails are born with their shells, which are soft at birth but continue to grow larger and stronger as the snail grows in size. The consumption of calcium also helps strengthen a snail’s shell. Wherever they live, all snails must come out of their shells to find food and reproduce.

Why is my snail hanging out of shell?

If you can’t see the body of the snail inside the shell, or if the body is hanging out of the shell without moving, the snail is most likely dead.

The former is a solid spiral-shaped structure carried on the back, made of a single piece and consisting mostly of calcium carbonate. The central layer of the shell, called ostracum,…

Why do snails change shape as they age?

The radius of the shell increases exponentially as the snail ages (i.e., the rate of radial growth is proportional to the shell radius) and, The angle between the centre of the snail and the end of the shell changes at a constant rate – like the second hand of a clock which moves at a constant rate of 360-degrees per minute.

What are the shell features of eastern Australian land snails?
