We were tracking a pod of bottle nose dolphin (Tursiops truncatus) in the water just past the backline off Ponta Malangane, when all of a sudden this plume of brown ‘smoke” erupted from the back of the pod, not unlike the smoke that those acrobatic plans deploy to make their movements more easily identifiable from the ground. Only thing this was not smoke but dolphin shit. It should be said that the dolphin concerned had the decency to let rip at the back of the pod. Not sure if this qualifies as evidence of decency, being a sample of one, but definitely evidence of the human talent for idealization!
