Snails can be found in a wide range of environments including ditches, deserts, and the abyssal depths of the sea. Although many people are familiar with terrestrial snails, land snails are in the minority. Marine snails constitute the majority of snail species, and have much greater diversity and a greater biomass. .Numerous kinds of snail can also be found in fresh waters.^ Found in fresh and brackish water along the Atlantic coast of Florida north to Maryland .

Types of snails by habitat

Slugs

.Gastropod species which lack a conspicuous shell are commonly called slugs rather than snails, although, other than having a reduced shell or no shell at all, there are really no appreciable differences between a slug and a snail except in habitat and behavior.^ No constant difference between the two species is apparent in the shell.

.A shell-less animal is much more maneuverable and compressible, and thus even quite large land slugs can take advantage of habitats or retreats with very little space, squeezing themselves into places that would be inaccessible to a similar-sized snail, such as under loose bark on trees or under stone slabs, logs or wooden boards lying on the ground.^ Considering that the depth of Stellwagen Bank is roughly 100ft in depth, it takes little to no effort for one of these animals to dive to the bottom and up, no more effort than it takes a person to walk a few steps.

^ The bodies of large snails, such as viviparids and pilids, should be pulled from the shell.

.In other words, the reduction or loss of the shell has evolved many times independently within several very different lineages of gastropods, thus the various families of slugs are very often not closely related to one another.^ Shell thin, fragile, very much depressed, less than 0.25 times as high as long.

^ These creatures are also extremely independent and almost never seen with another, unless: they are a mother and calf in which they are together for up to a year; they are mating, in which they still do not keep any form of relationship that lasts substantial time; or they are feeding, where one whale hear the other and went to see if they could join.

^ Something very interesting was explained to us was that they rest differently than other animals.
