Lagenorhynchus obscurus, better known as the Dusky Dolphin, is slightly smaller than most members of the Delphinidae family. They mostly live around New Zealand, but they are also found around South America and South Africa. Dusky Dolphins travel in large pods, and are especially recognizable by their unique two-toned dorsal fins. Because of their acrobatic skill, they are favorites among dolphin enthusiasts.
