The word "Arctoidea" is a scientific term used to refer to a group of mammals that includes bears, raccoons, and their relatives. The spelling of "Arctoidea" is derived from the Greek words "arktos" meaning bear and "oeides" meaning resembling. In IPA phonetic transcription, "Arctoidea" is pronounced as /ɑrkˈtɔɪdɪə/. The first syllable is pronounced as "ark", followed by "toi" which rhymes with "toy", and ending with "diah" which is pronounced as "dee-uh".
Arctoidea is a scientific term used in biology to refer to a superfamily of mammalian carnivores that includes bears (Ursidae) and their closest living relatives, the pinnipeds (seals, sea lions, and walruses). The term "Arctoidea" is derived from the Greek words "arktos" meaning bear and "oides" meaning resembling, indicating that the animals within this superfamily bear a resemblance to bears.
Members of the Arctoidea superfamily share certain characteristics, such as a plantigrade stance (walking on the entire sole of the foot) and the ability to hyper-extend their forelimbs. This superfamily also includes several extinct families, such as the extinct bear-dog family (Amphicyonidae) and the extinct aquatic bear family (Enaliarctidae).
Arctoidea is a diverse group of animals that have adapted to various habitats, including terrestrial, semi-aquatic, and marine environments. Bears, for example, are primarily terrestrial mammals with a wide distribution across the globe, while pinnipeds are marine mammals that spend part of their lives both in the water and on land. Despite the differences in habitat and lifestyle, all Arctoidea members share a common ancestry and exhibit certain anatomical and genetic similarities.
As a superfamily, Arctoidea plays a crucial ecological role as predators and apex predators in their respective habitats. They exhibit a range of physical and behavioral adaptations that allow them to hunt, catch and consume prey efficiently, contributing to the balance of ecosystems they inhabit.
The word "Arctoidea" is derived from two Greek roots: "arctos" meaning "bear" and "oides" meaning "resembling". Therefore, "Arctoidea" can be translated as "resembling a bear". This term is used in taxonomy to refer to a superfamily of carnivorous mammals that includes bears, raccoons, and their relatives.
