A snail is, in loose terms, a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name snail is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also numerous species of sea snails and freshwater snails. Gastropods that naturally lack a shell, or have only an internal shell, are mostly called slugs, and land snails that have only a very small shell are often called semi-slugs.
Whelk is a common name that is applied to various kinds of sea snail. Although a number of whelks are relatively large and are in the family Buccinidae, the word whelk is also applied to some other marine gastropod species within several families of sea snails that are not very closely related.
The Bahamas sawshark, Pristiophorus schroederi, is a sawshark of the family Pristiophoridae, found in the western Central Atlantic Ocean from the Bahamas and Cuba at depths of between 400 and 1,000 m. These sharks are at least 80 cm long.
Bathyclupea is a genus of perciform fishes belonging to a small family Bathyclupeidae.
Sea snail is a common name for snails that normally live in salt water, in other words marine gastropods. The taxonomic class Gastropoda also includes snails that live in other habitats, such as land snails and freshwater snails. Many species of sea snails are edible and exploited as food sources by humans.
A land snail is any of the numerous species of snail that live on land, as opposed to sea snails and freshwater snails. Land snail is the common name for terrestrial gastropod mollusks that have shells. However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water.
† Prisciphoridae is an extinct family of sea snails, marine gastropod mollusks in the clade Sorbeoconcha.
Lissodrillia schroederi is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.

Aspella schroederi is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.

Ecsenius schroederi, known commonly as the Schroeder's combtooth-blenny in Indonesia, is a species of combtooth blenny in the genus Ecsenius. It is found in coral reefs in the western Pacific ocean, specifically in Indonesia. It can reach a maximum length of 7 centimetres. Blennies in this species feed primarily off of plants, including benthic algae and weeds, and are commercial aquarium fish. The species was named in honour of the wildlife artist and scientific illustrator Jack R. Schroeder (1954-2004).
Panamericansaurus is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Period of what is now South America. It is very similar to the closely related Aeolosaurus, differing only in details of the vertebrae.
Liolaemus schroederi is a species of lizard in the family Iguanidae. The species is endemic to Chile, with endemic occurrence noted in the Chilean matorral.
Turbolidium is a genus of sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.
Lissodrillia is a genus of sea snails, marine gastropod mollusks in the family Drilliidae.
Terrestrial molluscs or land molluscs (mollusks) are ecological group that includes all molluscs that lives on land in contrast to freshwater and marine molluscs.
Eichstaettisaurus is a genus of gekkonomorph lizards, closely related to geckos, from the Late Jurassic and Early Cretaceous of Germany and Italy respectively. With a flattened head, a blunt snout, forward-oriented and partially symmetrical feet, and large claws, Eichstaettisaurus bears many adaptations to a climbing lifestyle approaching those of geckos. The type species, E. schroederi, is among the oldest and most complete members of the Squamata, being known by one specimen originating from the Tithonian-aged Solnhofen Limestone of Germany. A second species, E. gouldi, was described from another skeleton found in the Matese Mountains of Italy. Despite being very similar to E. schroederi, it lived much later, during the Albian epoch.
Brachypelma schroederi is a species of spiders in the family Theraphosidae (tarantulas), found in Mexico. It is found in the central valley in Oaxaca State, Mexico.
