Since the infecting organisms are common in salt water, we cannot be sure where or when he picked them up. It may be that they entered through one of his deep skin lesions. There is no evidence of human interaction in Nemo's death. Some volunteers have been very distressed at the need for a necropsy on Nemo, feeling that it would have been more appropriate for him to be buried or cremated without examination. We certainly can empath-ize with that feeling.
Many people become very attached to a dolphin during the course of rehabilitation.
However, there is another perspective that I would like to share with you. You are perhaps aware of the great success the Network veterinarians and scientists have had in rehabilitating strandings. Typically, when a dolphin strands it is either very young and separated from its mother, or it is desperately ill. It will die in a short time, either of disease or because of hyperthermia and heart and respiratory failure. It has been usual for animals to die despite treatment.
