Hector's Dolphin is the smallest and rarest marine dolphin in the world. They are unique in their distinct black facial markings. short, stocky bodies and a dorsal fin shaped like a Mickey Mouse ear. Hector's Dolphins are found around the coastal waters of New Zealand. However, this provides a problem for them as they are often caught as a result of fishery bycatch. Other threats include being struck by boats, pollution in their habitat, coastal development, and seabed mining. All of this has led to the Hector's Dolphin having a population of only 7,000 and decreasing.
