A blue whale in Chile had a rough week, zigging and zagging at a hectic pace as it dodged moving ships in a busy gulf, as seen in a new and dizzying visualization of the behemoth’s attempt to feed without getting struck by any of the swiftly moving vessels nearby.

The animation is part of a new study detailing the dangers posed by ship traffic to blue whales (Balaenoptera musculus) in one of their main feeding areas in the South Pacific. Researchers discovered that blue whales there could encounter as many as 1,000 vessels per day during summer months, when the animals migrate to this ocean region to feed and care for their young calves.
