Torpedo puelcha (lat.) - a type of slopes of the genus of the gnusov family of the gneusovyh detachment of electric rays . These are cartilaginous fishes that lead to a bottom lifestyle, with large, flattened pectoral and ventral fins forming a disk, a short and thick tail, two dorsal fins and a well-developed tail fin. Like other members of their family are able to generate electric current . They live in the southeastern part of the Atlantic Ocean at a depth of about 600 m. The maximum recorded length is 104 cm. They reproduce by breeding eggs . Not of interest for commercial fisheries [1] .

Content
For the first time a new species was described in 1926 [2] . The etymology of the specific epithet is not clear. Some species of animals that live in Argentina are also called puelcha , for example, bivalves , perhaps due to the name of the Puelcha people who inhabited central Argentina before the arrival of Europeans [3] . In 1982, a repeated description of the species was made and compared to a black electric ramp [1] .
Torpedo puelcha inhabit the southeastern part of the Atlantic Ocean off the coast of Argentina, Brazil and Uruguay . They are found on the continental shelf and the continental slope at a depth of about 600 m, in general, in the waters of Argentina and Brazil, they prefer to stay deeper [1] .
The pectoral fins of these rays form an almost oval disc. On both sides of the head, electrical paired organs in the shape of the kidneys are visible through the skin. Behind the small eyes are the squiggles . On the underside of the disk are five pairs of gill slits.
The tail is short and thick, ending in a small triangular tail fin. Two small dorsal fins shifted toward the tail. The maximum recorded length is 104 cm [1] [4] .
Like other members of their squad, Torpedo puelcha can generate electricity. They multiply by egg production. Males and females reach sexual maturity at a length of 60 and 65 cm, respectively [1] .
Torpedo puelcha is of no interest to commercial fishing. As a by- catch, they are regularly caught in commercial bottom fishing. Caught fish are thrown overboard. Data for assessing the conservation status of the species by the International Union for Conservation of the Nature is insufficient [1] .
