The green sea turtle year, in real records

The most-recorded reptile in the sea — sightings hug warm coastlines and seagrass beds around the entire tropical belt, year-round. The map above animates 43,888 recorded observations of Chelonia mydas — CC0 and CC BY 4.0 records accessed through GBIF, binned by calendar month, peaking in May. Sightings are history, not a forecast: they show where people have actually seen this animal, which is strong planning context and never a guarantee.

Where the year peaks

The regions holding the most recorded green sea turtle sightings, and the months when each one runs hottest — computed from the same dataset the map animates.
