Announced October 23, 2023:

This issuance encourages the protection of sea turtles, one of the oldest groups of animals on Earth. These ancient mariners can migrate long distances, sometimes crossing entire oceans. The pane of 18 stamps features close-up photographs of six species — the loggerhead, leatherback, hawksbill, Kemp’s ridley, olive ridley and green sea turtle — that depend on U.S. coastal waters for foraging and migratory habitats during various stages of their life. All six are listed and protected under the Endangered Species Act. Derry Noyes, an art director for USPS, designed the stamps and stamp pane using existing images.

Further information will be posted below the line, with the newest information at the top.
