The Patagonian toothfish (Dissostichus eleginoides), also known as Chilean sea bass, mero, and icefish, [2] is a species of notothen found in cold waters (1–4 °C or 34–39 °F) between depths of 45 and 3,850 m (150 and 12,630 ft) in the southern Atlantic, Pacific, and Indian Oceans and Southern Ocean on seamounts and continental shelves around most Subantarctic islands.
The many Orestias species in Lake Titicaca differ significantly in both habitat preference [35] and feeding behavior. [36] About 90% of the fish species in the basin are endemic, [34] including 23 species of Orestias that only are found in the lake. [37] Andean coot among totora sedges
They are found in lakes, rivers and springs in the Andean highlands of South America, and several species are considered threatened. [2] They are egg-laying fish that feed on small animals and plant matter. [3] [4] The largest species can reach a total length of 27 cm (10.6 in), but most remain far smaller.
Each species of Orestias has varying size. The Titicaca orestias was the largest species in the genus. [4] The maximum recorded size is 22 cm (8.7 in) in standard length and 27 cm (10.6 in) in total length, which is considerably larger than most other species; only O. pentlandii at up to 20 cm (7.9 in) and 23.5 cm (9.3 in), respectively, comes close.
Many endemic plant and animal species are currently threatened in the Tropical Andes. An example of a threatened plant species is the Andean bromelilad, an endemic plant that takes up to 100 years to mature and a common diet for species that forage. Other plant species include many crops such as tobacco and potatoes.
