astronomy-to-zoology: Southern Right Whale Dolphin (Lissodelphis peronii)

is a small species of dolphin found in cold subantarctic waters, as its name suggests, but some can be found in some subtropical waters like in Australia, South Africa and South America. This species is the only species of dolphin without a dorsal fin that can be found in the southern hemisphere, they are also distinct in their coloration as they have a sleek body with a black upper side and a white underside making them easily identifiable. They behave like most dolphins as they live in large to small groups and will often leap out of the water and bow-ride boats.
