Drift whale subclass of carcass
In historical sources, it is not always clear whether a given cetacean washed up alive or dead, but the term "drift whale" focuses on the benefits of its carcass – meat, blubber, fat, and other products – to the people who claimed it. Nowadays, when a dead whale washes up on a beach, often the authorities are required to dispose of it as a potential hazard to human health, so the resource implications go the other way: a drift whale is no longer a benefit to a community, but an expensive disadvantage.
