Feature and Habit
The hourglass dolphins distributed in a circumpolar pattern in the higher latitudes of the southern oceans. They are the smallest species among the Genus Lagenorhynchus. Hourglass dolphins are strikingly marked; black above and white below. White markings resemble an hourglasss in shape and give the dolphin its common name. Adult males have markedly curved dorsal fin, which indicates they are sexually matured. The maximum lengths and weights so far recorded were 190cm and 94kg (males), and 180cm and 88kg (females). Males are usually smaller than females in size. Groups of 1-8 are common.
