Some strandings can serve as indicators of ocean health, giving insight into larger environmental issues that can have implications for human health and welfare. The beaked whale family is cryptic and skittish, and distinguishing between species in the field can be challenging. We work with volunteer networks in all coastal states to respond to marine mammal strandings. They often form mixed schools with Atlantic white-sided dolphins and bottlenose dolphins when feeding, or travel alongside humpback or fin whales. In December of 2010, two whales—an adult female and a male calf—beached themselves on Opape Beach in the Bay of Plenty, New Zealand.
