During the trip on the 14^th of June, our team encountered two humpback whale individuals, one of which was entangled in fishing gear. A fishing line is cut into his tail stock, causing the animal to show behaviours such as "lobtailing", obviously trying to rid itself from the foreign body. Looking at the picture, it is unlikely that it will manage without help, since the fishing line is wrapped tightly, creating rather deep cuts into the blubber. An infection and tissue necrosis of the wound could result in a painful death.

Wounds resulting from entanglements can often be seen on the posterior caudal peduncle (the narrowing of the body at the insertion point of the flukes). These wounds can remain visible as unique scarring patterns years after the entanglement incident.
