The Southern River Otter inhabits the rivers, lakes, and coastal marine habitats in Chile and Argentina. They have an elongated body reaching up to 3.8 feet and 22 pounds.
Their diet is varied, from fish to crustaceans and mollusks. However, they also prey on small birds and mammals when the opportunity arises.

Hypostomus commersoni[1] is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the ParanΓ‘ River drainage, including the Iguazu River, the Paraguay River, the RΓo de la Plata, and the Dulce River. It is typically found in rivers with muddy substrates and moderate currents. The water that H. commersoni inhabits usually has a temperature of 16.8 to 27.8 Β°C (62.2 to 82.0 Β°F), a pH of 7.2 to 9.2, a turbidity of 23.7 to 442 NTU, an oxygen concentration of 6.1 to 9.1 mg/L, and a conductivity of 1.087 to 2.654 ΞΌS/cm.[2]
The zebra bullhead shark (Heterodontus zebra) is a bullhead shark of the family Heterodontidae found in the central Indo-Pacific between latitudes 40Β°N and 20Β°S, from Japan and Korea to Australia.[1][2] It is typically found at relatively shallow depths down to 50 m (160 ft), but off Western Australia, it occurs between 150 and 200 m (490 and 660 ft).[1] It can reach a length of 1.25 m (4.1 ft).[2] The reproduction of this bullhead shark is oviparous.[2]
Naja is a genus of venomous elapid snakes commonly known as cobras (or "true cobras"). Various species occur throughout Africa, Southwest Asia, South Asia, and Southeast Asia. Several other elapid species are often called "cobras", such as the king cobra and the rinkhals, but they are not "true cobras", in that they do not belong to the genus Naja.[1][2][3]
The black-necked spitting cobra (Naja nigricollis) is a species of spitting cobra found mostly in sub-Saharan Africa. They are moderately sized snakes that can grow to a length of 1.2 to 2.2 m (3.9 to 7.2 ft) in length. Their coloration and markings can vary considerably. They prey primarily on small rodents. They possess medically significant venom, although the mortality rate for untreated bites on humans is relatively low (~ 5β10%, in endemic regions under 1%). Like other spitting cobras, they can eject venom from their fangs when threatened (one drop over 7 metres (23 ft) and more in perfect accuracy). The cytotoxic venom irritates the skin, causing blisters and inflammation, and can cause permanent blindness if the venom makes contact with the eyes and is not washed off.
The rinkhals (/ΛrΙͺΕk(h)Γ¦ls/; Hemachatus haemachatus), also known as the ringhals /ΛrΙͺΕhΓ¦ls/[4] or ring-necked spitting cobra,[5] is a species of venomous snake in the family Elapidae. The species is found in parts of southern Africa.[1][3] It is not a true cobra in that it does not belong to the genus Naja, but instead belongs to the monotypic genus Hemachatus. While rinkhals bear a great resemblance to true cobras, they also possess some remarkable differences from these, resulting in their placement outside the genus Naja.[6] In 2023, the Zimbabwe population was described as a new species, H. nyangensis.[7]

The glowlight danio (Danio choprae) is a small, schooling fish closely related to the popular zebrafish Danio rerio. This should not be confused with the GloFish, a trademarked brand of fluorescent zebrafish that appear to glow in the dark under ultraviolet light.
