#Artio
- Anthracotherium — An extinct genus of hippopotamus-like artiodactyl ungulates within the family Anthracotheriidae, that lived during the Oligocene and Miocene epochs across Eurasia and Africa, adapted to a semi-aquatic lifestyle.
- Artio — A goddess in Celtic mythology, protector of bears, wildlife, and fertility, worshipped in antiquity particularly in the region of modern-day Switzerland. In iconographic and historical structures, her artistic representations often depict her alongside a large bear, symbolizing the regenerative force of the forest and nature's abundance.
- Artiodactyl — An even-toed ungulate mammal that possesses an even number of digits on each foot (two or four), with the axis of the foot passing between the third and fourth digits, which are the most developed; relating to these mammals. Taxonomically, this group includes animals such as Suina (pigs), Tylopoda (camels), and Ruminantia (deer, cows, sheep), structurally adapted for running or rumination.
- Artioploid — An organism or polyploid cell that possesses an even number of complete chromosome sets (for example, tetraploid, hexaploid, octaploid); relating to this numerical condition of the genome. In plant and evolutionary genetics, this structure ensures higher meiotic stability compared to perissoploid (odd) forms, allowing normal fertility and regular genetic segregation.
- Artiozoans — A rare or historical scientific name used to designate a hypothetical taxonomic group or a phylum of invertebrate animals with perfect bilateral symmetry or evenly structured segments. In early evolutionary studies, the term characterized organisms whose internal and external organization conformed to a strict numerical geometry divisible by two.
