Dolphin pathologies

Living in an area with high inputs of toxic contaminants, and spending much time foraging in polluted waters near appalling industrial plants, it is no surprise that some bottlenose dolphins in the Gulf of Evia show physical deformities suggestive of tumours—such as the one shown in this photo.

Luckily, this dolphin (nicknamed 'Bubbo') still shows a normal behaviour and is often seen socialising with others while moving from fish farm to fish farm.
