Humpback Whale Emerging from the Water with Multiple Parasites | Chatham Strait, Alaska

The rostrum of a humpback whale (Megaptera novaeangliae) emerging from the water. This whale was part of a group of humpback whales engaged in cooperative bubble-net feeding. Viewing this image at 100%, you can see the tubercles (including single follicles of hair protruding from some of them), an injury to one of the tubercles, and a few whale lice (Cyamus boopis) at the tip of the lower jaw. Note also the barnacles under the jaw, which are humpback whale barnacles (Coronula diadema), that grow only on humpback whales. In addition, growing on the humpback whale barnacles are a type of gooseneck barnacle (Conchoderma auritum), that appear only on humpback whale barnacles.
