Desert snail By Prapti and Aydan

A Desert Snail THIS A DESERT SNAIL Their shell has adapted to keep the desert snail cool and safe. THIS A DESERT SNAIL Good listening skills.

Shell Protection Snails' shells protect them from predators and the elements, and different snails have different adaptations, depending upon the regions they inhabit. Cone snails, for example, have evolved to sport large, cone-shaped shells that help them burrow into ocean sand. Additionally, the shape of the shell makes it difficult for crabs {cone snails' natural enemies}to grasp their slanted lengths. Other adaptations are shell patterns that serve as camouflage and shell thickness that preserves moisture.

Breathing Ways Freshwater and marine snails have evolved gills, while terrestrial snails also known as the desert snail sport fully formed lungs. Golden apple snails have adapted by possessing both a lung and gills. They can absorb oxygen straight from the water or siphon air through a tube on the left side of the body. This adaptation means they can travel from water source to water source and can survive in polluted aquatic environments. Their ability to directly breathe allows them to lay their eggs outside of water and away from hungry fish. These specific snails aren’t like all types of snails. They have lungs just like us which is cool.

Slime Protection Snail slime (or its cosmetic name, snail filtrate) is packed with nutrients such as hyaluronic acid, glycoprotein, proteoglycans, and antimicrobial and copper peptides, all of which are commonly used in beauty products and proven to be beneficial for the skin. These elements help to protect the snail’s skin from damage, infection, dryness and UV rays. Snail slime contains 91-98% water. The slime is filtered multiple times to increase its concentration and ensure its purity. Some snail slime products claim to contain as much as 97% snail secretion filtrate. However, the consistency and quality of the snail mucus should also be taken into account when looking for a good product.

Body Adaptations Snails' fascinating bodies are capable of incredible change and adaptation. The eyes of water-dwelling and land snails have adapted to perch on two eye stalks that can retract and extend from the snails' bodies. These eye stalks slip inside-out when retracting, protecting the snails' eyesight from predators, turf wars and the elements. Snail bodies have adapted for reproduction; snails are hermaphroditic -- they can change gender if necessary to procreate. In addition to their ability to change gender, some snails can self-fertilize and reproduce as gender.

Sleeping The reason snails sleep are they alike many other animals hibernate. Hibernation means that snails sleep when  weather becomes excessively cold; it is a necessary for the survival of snails. It is also been known some species of desert snails can do this for years before actually dying. Snails common diet are plants and other vegetation. Snails will bury themselves in the ground and close their shells off with their own slime. You can find them eating live plants, dying plants, rotting plants, fruits, and algae. A snail has a radula located inside its mouth to assist in the grinding of its food. 

This is a diagram that shows the different parts of a desert snail and you can see this snail has nearly everything that we have in our body. A snail is a tiny thing but it can handle all of these body parts.

Habitats Desert snails usually are found in hot and dry areas. Desert snails like to feel free to move in different areas so that's why they like to be in deserts because that habitat is a really empty habitat. Deserts take up 20% of the earth so think how big deserts are. Usually desert snails don’t have as much to eat but whatever they find is whatever they eat. But there is a problem as well as plants living in the desert human also do and the desert snails are starting to eat every food and are acting like rats.

Glossary Habitat- The natural home or environment of an animal, plant, or other organism. Hibernate- (Of an animal or plant) spend the winter in a dormant state. Dwelling- A house, flat, or other place of residence but for a snail it is a water habitat. Elements- A part of something. Hermaphroditic- An organism, such as an earthworm or flowering plant, having both male and female reproductive organs in a single individual.  Glycoprotein- Any of a class of proteins which have carbohydrate groups attached to the polypeptide chain. Proteoglycans- A compound consisting of a protein bonded to mucopolysaccharide groups, present especially in connective tissue.
