This species is named "smooth hammerhead" because of the distinctive shape of the head, which is flattened and laterally extended into a hammer shape, without an indentation in the middle of the front margin. Unlike other hammerheads, this species prefers temperate waters and occurs worldwide at medium latitudes. In the summer, these sharks migrate towards the poles following cool water masses, sometimes forming schools numbering in the hundreds to thousands.

It is a member of the river dolphin group and the only one that lives in the ocean and saltwater estuaries, rather than inhabiting exclusively freshwater systems. Commercialized areas that create agricultural runoffs and/or industrialized zones can affect the health of the La Plata dolphin, especially in regards to their contributions of waste and pollution, which can lead to habitat degradation and poisoned food among other concerns.

WThe pacarana is a rare and slow-moving hystricognath rodent indigenous to South America. Native Tupi people call it the pacarana because it is superficially similar to the paca, a different rodent which is not in the same family. The pacarana has a chunky body and is large for a rodent, weighing up to 15 kg (33 lb) and measuring up to 79 cm (31 in) in length, not including the thick, furry tail.
WThe red-footed tortoise is a species of tortoise from northern South America. These medium-sized tortoises generally average 30 cm (12 in) as adults, but can reach over 40 cm (16 in). They have dark-colored, loaf-shaped carapaces with a lighter patch in the middle of each scute, and dark limbs with brightly colored scales that range from pale yellow to dark red. Recognized differences are seen between red-footed tortoises from different regions. They are closely related to the yellow-footed tortoise from the Amazon Basin. They are popularly kept as pets, and over-collection has caused them to be vulnerable to extinction.
WThe red-headed Amazon side-necked turtle, red-headed river turtle, or red-headed sideneck is a species of turtle in the family Podocnemididae. It is found in the Amazon basin in Brazil, Colombia, and Venezuela.
WReig's opossum is a South American opossum species of the family Didelphidae, discovered in 2004. It is named after Argentine biologist Osvaldo Reig (1929–1992).

It inhabits the desert Pacific coastal region with Mediterranean influences and is found in and near oases and streams. Breeding takes place in permanent pools, streams, and rivers. While abundant at a few sites, it has declined overall and gone locally extinct at some sites. Threats to this species include extensive droughts and water pollution as well as extraction of surface water, mining, agriculture, livestock farming, and timber plantations.
WThe dusky shark is a species of requiem shark, in the family Carcharhinidae, occurring in tropical and warm-temperate continental seas worldwide. A generalist apex predator, the dusky shark can be found from the coast to the outer continental shelf and adjacent pelagic waters, and has been recorded from a depth of 400 m (1,300 ft). Populations migrate seasonally towards the poles in the summer and towards the equator in the winter, traveling hundreds to thousands of kilometers. One of the largest members of its genus, the dusky shark reaches 4.2 m (14 ft) in length and 347 kg (765 lb) in weight. It has a slender, streamlined body and can be identified by its short round snout, long sickle-shaped pectoral fins, ridge between the first and second dorsal fins, and faintly marked fins.
WThe night shark is a species of requiem shark, in the family Carcharhinidae, found in the temperate and tropical waters of the Atlantic Ocean. An inhabitant of the outer continental shelf and upper continental slope, this shark most commonly occurs at depths of 50–600 m (160–1,970 ft) and conducts a diel vertical migration, spending the day in deeper water and moving into shallower waters at night. Off northeastern Brazil, large numbers congregate around seamounts of varying depths. A slender, streamlined species, the night shark typically reaches a length of 2 m (6.6 ft). It can be identified by its long, pointed snout and large, green eyes, and is dark grayish blue or brown above and white below.
WThe school shark is a houndshark of the family Triakidae, and the only member of the genus Galeorhinus. Common names also include tope shark, snapper shark, and soupfin shark. It is found worldwide in temperate seas at depths down to about 800 m (2,600 ft). It can grow to nearly 2 m long. It feeds both in midwater and near the seabed, and its reproduction is ovoviviparous. This shark is caught in fisheries for its flesh, its fins, and its liver, which has a very high vitamin A content. The IUCN has classified this species as critically endangered in its Red List of Threatened Species.
WThe oceanic whitetip shark, also known as Brown Milbert's sand bar shark, brown shark, lesser white shark, nigano shark, oceanic white-tipped whaler, and silvertip shark, is a large pelagic requiem shark inhabiting tropical and warm temperate seas.

Its closest relatives are the extinct Florida spectacled bear, and the giant short-faced bears of the Middle to Late Pleistocene age. Spectacled bears are the only surviving species of bear native to South America, and the only surviving member of the subfamily Tremarctinae. The species is classified as Vulnerable by the IUCN because of habitat loss.

This species can be recognized by its black or brown oval carapace with distinctive low keels on the second and third scutes. Yellow spots on the side of its head give this species its common name. These spots are most prominent in juveniles and fade with age. Females can be up to twice the size of males.
