The complete county distribution, spread across 3 Texas counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Atlantic spotted dolphins are open-water animals, and Texas’s 16 records almost certainly come from Gulf of Mexico waters, strandings, or boat-based sightings rather than from anywhere on land. Adults carry the pale spotting that gives the species its name, but young dolphins are born plain gray, so identification can shift with age.

The monthly counts are scattered and thin, a couple of reports most months with none at all in several, too few to point to a real seasonal pattern. NatureServe ranks the species S1, critically imperiled, in Texas even though its global status is secure, a reminder that a handful of Gulf records doesn’t add up to a healthy state population, just a species barely tracked this far into US waters.
