Spinner Dolphin
Stenella longirostris
Those times I'm lucky enough to hear whistles and clicking sounds I instantly change focus from finding small stuff, snails or whatever I'm up to at the moment, and instead scout for what could be dolphins. They are fast swimmers, so if they are around, they are not necessarily for long. Most often I will not find them, but sometimes I do, and some of these encounters I believe are the dolphins approaching me more than the other way around. They are curious, playful and intelligent creatures.
