frog : any of various largely aquatic leaping anuran amphibians (such as ranids) that have slender bodies with smooth moist skin and strong long hind legs with webbed feet — Merriam-Webster   See also   OneLook


Frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforests. There are approximately 4,800 recorded species, accounting for over 85% of extant amphibian species. They are also one of the five most diverse vertebrate orders. — Wikipedia

Articles about Frogs (Big Think)




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 June 5, 2023 at 10:12 pm

    Researchers show that an evolutionary change in the length of lizards' legs can have a significant impact on vegetation growth and spider populations on small islands in the Bahamas. This is one of the first times, the researchers say, that such dramatic evolution-to-environment effects have been documented in a natural setting.

    Scientists have developed and validated an assay that could be used to diagnose Indian strains of the amphibian chytrid fungus that were not detected by previous tests. The novel assay also works for other better-known strains from other parts of the world, such as the one present in Panama.

    on May 18, 2023 at 4:09 pm

    Scientists have discovered a new species of mosasaur, a sea-dwelling lizard from the age of the dinosaurs, with strange, ridged teeth unlike those of any known reptile. Along with other recent finds from Africa, it suggests that mosasaurs and other marine reptiles were evolving rapidly up until 66 million years ago, when they were wiped out by an asteroid along with the dinosaurs and around 90% of all species on Earth.

    An expedition into the jungle of New Guinea has resulted in the discovery of two new species of poisonous birds. Genetic changes in these bird species have allowed them to carry a powerful neurotoxin.

    A new study suggests that predatory dinosaurs, such as Tyrannosaurus rex, did not have permanently exposed teeth as depicted in films such as Jurassic Park, but instead had scaly, lizard-like lips covering and sealing their mouths. - latest science and technology news stories internet news portal provides the latest news on science including: Physics, Nanotechnology, Life Sciences, Space Science, Earth Science, Environment, Health and Medicine.

    Animals can defend themselves against their natural enemies in various ways. Well-defended species often share conspicuous body colors with other well-defended or undefended species, forming mimetic interactions.

  • Unraveling brood parasitism in predatory mites
    on June 6, 2023 at 5:44 pm

    Several animal species display brood care, a phenomenon where 'caring' parents provide their offspring with food and protection against predators. However, there are many others that prefer not to do this, and instead sneak in their eggs with those of other 'caring' species to take advantage of free brood care.

    on May 30, 2023 at 2:28 pm

    Senckenberg researchers have introduced a new invasion biology concept, so-called "nested invasions." Using Johnstone's whistling frog as an example, they show that this amphibian not only colonizes foreign regions, but it also carries invasive microbiomes in its baggage. The scientists thereby provide the first comprehensive dataset for an invasive community and warn of the still unknown impact on the newly colonized ecosystems.
