The complete county distribution, spread across 8 Florida counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Florida has only 19 spinner dolphin records, every one from GBIF rather than iNaturalist observations. That gap points to strandings or offshore research encounters rather than shore-based or boat sightings, and it’s far too few records to describe where the species concentrates in state waters.

July stands out with 6 records, the closest thing to a seasonal pattern in an otherwise sparse year. With such a small sample, that July cluster could easily be a handful of related reports rather than a real seasonal pull toward Florida waters.
