Both male and female whales reach puberty between the ages of 6 and 12 with an average of eight to nine years. The results are used to inform management decisions and enhance recovery efforts for this species. Some strandings can serve as indicators of ocean health, giving insight into larger environmental issues that may also have implications for human health and welfare. To understand the health of marine mammal populations, scientists study unusual mortality events. Scientists from the Namibian Dolphin Project confirmed the whale's identity and thus provides the only sighting of this species in the Southern Hemisphere. You may also contact your closest NOAA Office of Law Enforcement field office during regular business hours. This population ranged at least from Southampton, New York, to Jupiter Island, Florida, the latest from 1675. It is listed as endangered under the ESA and depleted under the MMPA.
