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.

The parks listed for this species, Big Bend, Balcones Canyonlands, and Big Thicket, are inland Texas locations that have nothing to do with where a pygmy sperm whale actually turns up. This is a deep-diving Gulf of Mexico whale, and its real Texas records come from offshore sightings and, more often, strandings on Gulf beaches. Pygmy sperm whales are notoriously hard to observe alive: they’re slow, quiet divers that tend to float motionless at the surface between dives, so most human encounters happen when a sick or dead animal washes ashore.

All 19 Texas records come through GBIF with no iNaturalist entries, consistent with stranding-response reports rather than casual wildlife sightings. NatureServe ranks the species S1, Critically Imperiled, in Texas, though for an elusive offshore species that status likely reflects how few confirmed records exist as much as true rarity. The monthly counts are too sparse and scattered to describe a real seasonal pattern.
