Apple snail
* Most apple snails have shells.
* Most apple snails survive in different habitats
* Some apple snails are unable to deposit their eggs on the surface they have climbed on.
* are also common aquarium pets because of their size
  - common aquarium pets, suited to the tropics
  - easy animals that do well in a common aquarium or a pond
  - herbivores, so they eat mostly aquatic vegetation, and algae
* die or estivate, becoming unavailable, when a site becomes dry.
+ Ampullariidae, Food and Digestion
  * Apple snails are herbivores, so they eat mostly aquatic vegetation, and algae. To digest food, apple snails first break up food with the radula teeth, and then the food will be swallowed, and travel down the esophagus and to the stomach. It will eventually exit through the anus as feces
  - Habitat: Gastropods
  * They eat things like fresh fruits, lettuce, other vegetables, algae and herbivorous wafers. However, they are not called apple snails because they eat apples. They get their name from the fact that one species of apple snails can grow to be the size of an apple. Apple snails are also common aquarium pets because of their size. They also prefer to be with other snails. Although they can live in water with high oxygen, this makes them move slower

Aquatic snail
* Most aquatic snails have gills, but land snails have a breathing chamber
  - reproduction
* are in other orders, and usually have gills
  - often carnivorous
  - somewhat different
* eat plants and algae at the bottom of the pond.
* have both hermaphroditic and heterosexual reproduction
+ Snail, Food
  * Land snails eat vegetables and fruits, such as lettuce, carrots, cucumber and apples. Aquatic snails are often carnivorous. Snails use their radula to cut food. The radula is a hard, rough plate in the mouth. Radula teeth are like little pieces of sandpaper. They are good for cutting up plants and if the snail eats meat they are good for tearing the meat apart. Radula teeth look like little fangs.
+ Snail: Gastropods
  * Usually, by 'snail' people mean the snails on land. Land snails usually have lungs, and are in the order Pulmonata. Aquatic snails are in other orders, and usually have gills. Close relatives of the snails are the slugs, which are basically snails without shells. Both slugs and snails are numerous and successful on land. Most land snails and slugs are herbivorous. Aquatic snails and slugs are usually omnivores or predatory carnivores.

Cone snail
* Most cone snails are nocturnal hunters so also feed when fish are sleeping
  - eat large meals
* Most cone snails have diverse patterns
* Some cone snails eat prey
  - have venom strong enough to kill humans, though they prefer using it on their prey
* are among the most venomous creatures on earth.
* inhabit warm water reefs in the Pacific and Atlantic regions.
* use an entire arsenal
  - their chemical overkill so that death comes as quickly as possible

### animal | mollusc | gastropod | snail:

Freshwater snail
* Many freshwater snails are also pulmonates.
* Most freshwater snails have chambers.
* Some freshwater snails have gills by which they obtain oxygen from the water
  - ranges
  - live in deep lakes, others live in lakes and ponds high in the mountains
  - provide food
* are common in ponds, streams, marshes, and lakes
  - gastropod mollusks which live in freshwater
  - intermediate hosts, essential to the parasite life-cycle
  - often hermaphrodites
  - wide range in life span depending on species and environment

Garden snail
* Most garden snails feed on plants.
* Most garden snails have female organs
  - reproductive organs
* Some garden snails can have babies
  - hibernate during winter
* move to yards.
