The snails are cooked and served in their shells. In Moroccan cuisine, snails also called Ghlal, are a popular street food. They are cooked in a jar filled with hot water, special spices, and herbs. After cooking, Moroccan snails are served in small bowls with broth and consumed hot.
A newly hatched snail's shell size depends on the egg size since the shell develops from the egg's surface membrane. As the snail grows, the shell is added in increments. Eventually, the shell develops a flare or reinforcing lip at its opening. This shows that the snail is now mature; no further shell growth can occur.
The snail extends the tentacles by internal pressure of body fluids, and retracts all four tentacles into the head by invagination when threatened or otherwise retreating into its shell. The mouth is located beneath the tentacles, and contains a chitinous radula with which the snail scrapes and manipulates food particles.
Theba pisana, common names the white garden snail, sand hill snail, white Italian snail, Mediterranean coastal snail, and simply just the Mediterranean snail, is an edible species of medium-sized, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicidae, the typical snails.
The shell of Zonitoides nitidus, a small land snail, has dextral coiling, which is typical (but not universal) of gastropod shells Main article: Gastropod shell Most shelled gastropods have a one piece shell (with exceptional bivalved gastropods ), typically coiled or spiraled, at least in the larval stage.
Helicidae is a large, diverse family of western Palaearctic, medium to large-sized, air-breathing land snails, sometimes called the "typical snails."It includes some of the largest European land snails, several species are common in anthropogenic habitats, and some became invasive on other continents.
Cantareus apertus, [2] commonly known as the green garden snail, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae, the typical snails. Distribution
A snail's shell forms a logarithmic spiral. Most snail shells are right-handed or dextral in coiling, meaning that if the shell is held with the apex (the tip, or the juvenile whorls) pointing towards the observer, the spiral proceeds in a clockwise direction from the apex to the opening.
