We report the case of a young coastal bottlenose dolphin (Tursiops truncatus) hooked and entangled in artisanal fishing gear on two occasions in a period of six months. In both occasions the animal managed to get rid of the gear by itself. The case occurred in the inner estuary of Gulf of Guayaquil, Ecuador. The animal survived both events, but scars remained in various parts of the body and missed fluke tips. Photographs of the individual after the events allowed to evaluate the healing process. This case demonstrated that longlines represents a threat for this population.
