tortoise : any of a family (Testudinidae) of terrestrial turtles — Merriam-Webster See also OneLook

Encyclopedia

Tortoises are a family, Testudinidae. Testudinidae is a Family under the order Testudines and suborder Cryptodira. There are fourteen extant families of the order Testudines, an order of reptile commonly known as turtles, tortoises, and terrapins. The suborder Cryptodira is a suborder of Testudines that includes most living tortoises and turtles. Cryptodira differ from Pluerodia in that they lower their necks and pull the heads straight back into the shells, instead of folding their necks sideways along the body under the shells’ marginals. The testudines are some of the most ancient reptiles alive. — Wikipedia

Science

Herpetology is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the scientific study of birds is the subject of ornithology. Thus, the definition of herpetology can be more precisely stated as the study of ectothermic (cold-blooded) tetrapods. Under this definition “herps” (or sometimes “herptiles” or “herpetofauna”) exclude fish, but it is not uncommon for herpetological and ichthyological scientific societies to collaborate. — Wikipedia
