Image 1 of 4:  A mighty Humpback Whale begins a deep dive by arching its back.  Deep scars can be seen along the dorsal ridge of the caudal peduncle, most likely from entanglement.
Image one of two tail fluke shots of this Gray Whale (Eschrichtius robustus) which show infected and encircling wounds plus scarring around the tail.  The Condor Express crew have theorized that this was caused by an entanglement.
