16 Different Types of Snail Giant African Land SnailĬredit: Manus Island tree snail is often called the emerald green snail due to its beautiful bright green shell. Wetting the shell can help bring out the texture and the color. Archachatina have much smaller and tighter-knit pores on the skin in comparison to Achatina snails. The sutures (the ridges along the spiral groove) of an Archachatina is deeper than an Achatina shell. If the apex (the tip of the shell) is pointed it’s an Achatina, if it’s blunt it’s an Archachatina. The texture of the shell and skin can also help determine what you are looking at. Some types of snail shells are ventricose, others are very slender, whilst some have increasing whorls. The profile of the whorls and their comparative size can also help determine the species. The number of whorls persent on the shell can help you easily identify the snail species. Most snails will have a conical shaped shell. When trying to identify the type of snail, the easiest method is to check it out closely. 286 million years ago the sea snail evolved into a land snail and developed lungs for breathing. The first snail is thought to have lived around 550 million years ago on the seafloor. Some snails are edible to humans, and even considered a delicacy in some countries, but be careful as many species of snails are dangerous because they contain parasites. Other snails will eat only animal-based food, whilst many eat both plants and meat. Most land snails only eat plant-based food because they are herbivores. Some snails can be found in your back garden, others live in the snow or in the desert, while some prefer to live up trees. Snails are adaptable animals that live almost all over the world. Despite many of them sharing the same features, they all have different diets, prefer different habitats, and come in unique shades. They have been categorized into land snails, sea snails and freshwater snails. There is thought to be over 43,000 species of snails in the world. Snails are molusks which belong to the gastropod class.
