How many pygmy right whales are left?

The pygmy right whale is among the least studied cetaceans (as of 2008 fewer than 25 "at sea" sightings of the species have been made). The species lives in the Southern Hemisphere and is believed to be circumpolar, living in a band from about 30 degrees south to 55 degrees south in areas with surface water temperature between 5 and 20 °C (41 and 68 °F). Individuals have been found on the coasts of Chile, Tierra del Fuego, Namibia, South Africa, Australia and New Zealand. One group may be a year-round resident off Tasmania. The total population is unknown.
