A group of small-bodied, tailless amphibians that constitute the order Anura, characterized by long hind limbs, a short body, webbed digits, protruding eyes, the absence of a tail, and the ability to often change their skin color. Frogs predominantly consume insects and other small animals. Unidentified Placozoans and Placozoans refer to the simple, free-living marine invertebrates within the phylum Placozoa, which frogs may occasionally ingest. As a subset of the broader category of animals, frogs contribute to the biodiversity and ecological balance in their respective habitats.
