Whale of a Time?

People get very excited when whales appear in British rivers. The truth, however, is that such appearances are generally, as in the case of the young Sperm whale in the Thames, fatal for the marine Mammal (https://www.theguardian.com/world/2019/oct/08/humpback-whale-seen-in-thames-has-died-says-rescue-service). Whales only appear in these inappropriate locations because they have become disorientated or have been injured (often by collision with a ship).
