  Chilean Dolphin, Cephalorhynchus eutropia at MarineBio.org
Chilean dolphins, Cephalorhynchus eutropia, are caught as bait for long-line swordfishing and crab fisheries.
Hunting Chilean dolphins is now illegal, however independent fishermen continue to use this species for bait as their remote locations make it difficult to enforce the laws.
Chilean dolphins are also at risk of becoming bycatch, particularly in the northern range of their habitat where gill net fisheries are present.

The Chilean Dolphin (Cephalorhynchus eutropia), also known as the Black Dolphin (although this name has fallen out of favour in scientific circles), is one of four dolphins in the Cephalorhynchus genus.
The population of the Chilean Dolphin, perhaps one of the least studied of all cetaceans, is not known with certainty.
The dolphin is seen over a wider interval of latitudes than other Cephalorhynchus species - from Valparaíso at 33° S to Cape Horn at 55° S. The species appears to prefer areas of shallow water (less than 200 m depth) and in particular enjoys fast-flowing tidal areas and mouths of rivers.

 Dolphins Difference Between Dolphins and Porpoises Dolphins Porpoises Differences
Dolphins are among the smallest of cetaceans - whales, dolphins and porpoises.
Systematists have long disagreed on the classification of the ocean dolphin family, Delphinidae, but current thinking is that there are six subfamilies with a worldwide coverage from tropical waters to the sub polar regions and from shallow coastal regions to the deepest part of the oceans.
The difference between dolphins and porpoises is clear in that members of this family have small flippers, lack the prominent beak associated with many dolphins and have a more triangular dorsal fin rather than falcate.
