The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of wolves. Also called the domestic dog, it was selectively bred during the Late Pleistocene by hunter-gatherers. Dogs and the modern gray wolf share a common ancestor. Dogs were the first species to be domesticated over 14,000 years ago, before the development of agriculture, though genetic studies suggest the domestication process may have begun over 25,000 years ago. Due to their long association with humans, dogs have gained the ability to thrive on a starch-rich diet that would be inadequate for other canids

The axolotl (; from ; Ambystoma mexicanum) is a species of paedomorphic mole salamander. They mature into their terrestrial adult form without undergoing metamorphosis; the adults remain fully aquatic with obvious external gills. This trait, although somewhat unusual among the majority of amphibians, is not unique. Axolotls may be difficult to distinguish from the larval stage of other neotenic adult mole salamanders, such as mudpuppies (Necturus spp.) or the occasionally paedomorphic tiger salamander (A. tigrinum).

The zebrafish (Danio rerio) is a species of danionin belonging to the genus Danio in the suborder Cyprinoidei. Native to South Asia, it is a popular, hardy aquarium fish, frequently sold under the trade name zebra danio (thus often mislabeled as a "tropical fish", even though they also inhabit subtropical and temperate waters).

Drosophila (; from Ancient Greek and ) is a genus of fly, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit. They should not be confused with the Tephritidae, a related family, which are also called fruit flies (sometimes referred to as "true fruit flies").

Xenopus () (from Greek ξενος, xenos 'strange' + πους, pous 'foot', commonly known as the clawed frog) is a genus of highly aquatic frogs native to sub-Saharan Africa. Twenty species are currently described within it. The two best-known species of this genus are Xenopus laevis and Xenopus tropicalis, which are commonly studied as model organisms for developmental biology, cell biology, toxicology, neuroscience and for modelling human disease and birth defects.
