Experienced whale-watchers can determine a whale's species just by spotting its spout. Orcas have bushy-shaped spouts, while humpback whales' spouts are column-shaped and gray whales' spouts are heart-shaped. But there are other distinctive features that can clue in keen observers, such as a whale's dorsal fin, the number of whales in a group, and a whale's tail flukes. (Humpback whales have tail flukes that are unique to each individual!) Even splashes and ripples have something to say about the cetaceans that left them: a large gathering of ripples might mean dolphins, whereas a big splash could be a humpback's breach.
