When we go on whalewatches, we are entering the world of humpback whales to encounter them in their natural environment. Passengers and crew are often astounded by the diverse behaviors and characteristics of these animals, but occasionally we are also presented with sobering reminders that threats to whales and other marine life are still very real. On one of our recent whalewatches out of Hervey Bay, Australia, all those aboard Ocean Defender were given a glimpse into humpback whale entanglement.
As we entered Platypus Bay we saw our first whale sighting of the day, and the level of excitement was rising. There was a whale swimming by itself, which is not unusual for a humpback whale, but after a few minutes it seemed there may be something wrong. This particular whale was acting stressed and swimming erratically. Then we noticed something odd; as the whale surfaced we could see a laceration on its dorsal fin from dragging several lines.
