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

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

Scientists discovered a new frog species in the flooded forests of the western Amazon, distinguishing it from nearly identical relatives through DNA and its unique call. Adenomera varcena highlights how much Amazonian biodiversity remains hidden even as habitat loss and climate change threaten these poorly understood species.

A 125-million-year-old crocodile fossil has revealed preserved skin, possible sensory organs, sophisticated respiratory structures, and an unexpected pattern on its tail. Ultraviolet light exposed alternating bands that may represent ancient camouflage, potentially preserving the oldest known coloration in a crocodylomorph.

More than 60 years after surveys suggested a deep coral reef off Benin was probably dead, scientists have found it alive. Cameras revealed healthy-looking coral patches supporting multiple fish species more than 50 meters beneath the surface. The discovery suggests West Africa’s coastal waters may contain other overlooked reefs that have yet to be documented.

Captive-raised saltwater crocodiles released into Bangladesh’s Sundarbans surprised scientists by settling into the wild rather than trying to return to their breeding facility. The result suggests that releasing larger, mature captive crocodiles could help restore depleted populations more successfully than relying only on vulnerable hatchlings.

Britain’s wasps have become mysteriously scarce this summer, and scientists suspect an unusual combination of temperature swings, heatwaves, and food shortages may be responsible. Even the wasps that remain appear unusually small, potentially offering a glimpse of how extreme heat could reshape insect populations.

Brigid Lynch was working along a wooded creek in a mountainous part of the San Francisco Bay Area when something that didn't look like the rocks she'd been studying caught her eye. It turned out to be the fossilized tooth of a Pacific mastodon.

Researchers at Stanford Medicine have developed two new artificial intelligence models of the biological cell. The first, called universal cell embedding, paved the way for a second-generation model called TranscriptFormer, which has been trained on data from 112 million cells representing 12 species, ranging from single-celled yeast to humans.

In taxonomy, the location where specimens used to formally describe a new species are collected is called a type locality. These sites can be thought of as the species' formal birthplace, much as the scientific article containing the original description constitutes its scientific birth certificate, because this is how the species officially acquires its identity and name within the scientific community.
