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


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

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

    on April 25, 2023 at 4:24 pm

    Many animals live in groups. One of the main benefits of this is shared knowledge. This information can help animals tackle problems such as where to find food and mates, how to follow migration routes and how to avoid predators.

    Associate Professor Jonathan Boreyko leads a team at Virginia Tech that has built a strong portfolio of work with ice and water, exploring the possibilities for de-icing planes, building novel water harvesting devices, and creating snow globes out of bubbles. This familiarity with water has given the team a strong sense of its behavior in different states, leading to a new project that shows how ice quenches heat in comparison to water. The findings were published in the journal Chem on April […]

    New research led by the University of Oxford has revealed that the most endangered turtle and crocodile species are those that are most unique. Their loss could have widespread impacts on the ecosystems they live in, since they carry out critical processes important for many other species.

    Many native animals that disperse plant seeds on the island of Mauritius have gone extinct during the past centuries. This includes iconic species such as the dodo and giant tortoises, now replaced by non-native fruit-eating animal species that have been introduced to Mauritius. However, the newly introduced species are not able to replace the extinct seed dispersers, according to a publication in the renowned scientific journal Nature Communications, to which UvA-IBED researcher W. Daniel […]
