Lagenorhynchus obscurus, commonly known as the dusky dolphin, is known for its striking black and white coloration and acrobatic displays. It inhabits the coastal waters of the Southern Hemisphere, particularly around New Zealand and South America. These dolphins are social animals, often found in large pods, and are skilled hunters, using cooperative techniques to catch fish.

Lagenorhynchus obscurus, commonly known as the dusky dolphin, is native to the coastal waters of the Southern Hemisphere. Its geographical distribution includes regions off the coasts of South America (particularly around Argentina, Chile, and Peru), southwestern Africa, around New Zealand, and the waters near Tasmania in Australia. Populations are often found along the continental shelf and slope waters.

Dusky dolphins typically inhabit temperate to subantarctic waters. They are often found in coastal areas, preferring waters that are less than 200 meters deep. The water temperatures in their native regions generally range from 10°C to 18°C. These dolphins are known to inhabit areas with complex underwater topographies, like canyons and seamounts, which provide rich feeding grounds.

Dusky dolphins occupy the ecological niche of a mid-level predator in marine ecosystems. They primarily feed on a variety of fish and squid, utilizing cooperative hunting techniques. Dusky dolphins rely on echolocation and agile swimming to hunt and are known for their acrobatic behaviors. They play a significant role in controlling the populations of their prey species and contribute to the overall health and balance of the marine ecosystems they inhabit.
