Arctosa cinerea is one of the most conspicuous wolf spider of central Europe. The spider reaches a length of 17 mm (males only 14 mm), and occurs only on sandy beaches of rivers, lakes and oceans. Its grey-brown color makes for a good camouflage, and so it is not often seen, even if it wanders around during daylight. They dig holes in the ground, which they cover with silk, or hide under rocks.

The Arctopsychidae are a family of net-spinning caddisflies. Larvae tend to live in clear, cold streams with stony bottoms. The larvae are often filter feeders, and will spin aquatic nets between stones to catch food particles. Adults will then emerge from the water to fly between late May and mid August. Distribution is holarctic and oriental.

Arctostaphylos otayensis is a species of manzanita known by the common name Otay manzanita. This shrub is endemic to California, where it is native to the mountains of San Diego County. It is an erect shrub, reaching up to 2.5 meters in height. It has shreddy red bark that grows gray with age. It has smooth oval-shaped pointed leaves and dense inflorescences of flowers. The tightly bunched flowers are pale pink highlighted with bright magenta. The fruit is a red drupe between one half and one centimeter wide.

Arctostaphylos mendocinoensis is a species of manzanita known by the common name Pygmy manzanita. It is endemic to Mendocino County, California and Sonoma County, California, where it is known from only one occurrence in the pygmy forests along the coastline. This is a small, mat-forming shrub growing in low mounds less than half a meter tall. It has red, shreddy bark and bristles along its smaller branches.

Arctosaurus (meaning "arctic lizard") is an extinct genus of reptile originally classified as a small reptile of unknown affinities, but was often classified as a sauropodomorph dinosaur in the years to follow. Although it has also been classified as a theropod, recent review finds that the similarities it shares with theropods are spread throughout several groups of Late Triassic reptiles, and so it cannot be assigned any more specifically than to Archosauriformes. Other authors have suggested trilophosaurian affinities. It is based on a neck vertebra that was found on Cameron Island, Nunavut, Canada, in Late Triassic-age rocks. Recently, new material of Arctosaurus osborni was unearthed in Canada.

Arctostaphylos nortensis, common name Del Norte manzanita, is a shrub narrowly endemic to the mountains along the Oregon/California state line. It has been reported from only 3 counties: Del Norte County, California; and Curry and Josephine Counties in Oregon. The plant grows in chaparral and open forests at elevations of 400–600 m (1,300–2,000 ft).Arctostaphylos nortensis is a shrub up to 5 m (16 ft) tall, bearing racemes of white flowers.

Arctostaphylos (/ˌɑːrktoʊˈstæfᵻləs, -lɒs/; arkto bear + staphyle grape) is a genus of plants comprising the manzanitas (/ˌmænzəˈniːtəz/) and bearberries. They are shrubs or small trees.There are about 60 species of Arctostaphylos, ranging from ground-hugging arctic, coastal, and mountain species to small trees up to 6 m tall. Most are evergreen (one species deciduous), with small oval leaves 1–7 cm long, arranged spirally on the stems. The flowers are bell-shaped, white or pale pink, and borne in small clusters of 2-20 together; flowering is in the spring. The fruit are small berries, ripening in the summer or autumn. The berries of some species are edible.Arctostaphylos species are used as food plants by the larvae of some Lepidoptera species including Coleophora arctostaphyli (which feeds exclusively on A. uva-ursi) and Coleophora glaucella.
