Where it lives

Gulf of Mexico and the US Atlantic coast

Ranges stay general on purpose. Witness never publishes a location that could help someone find an animal already under pressure.

What threatens it

  • Fishing-gear bycatch
  • Cold-stunning events
  • Oil spills
  • Historic egg harvest

Life cycle

Females come ashore in daylight arribadas every one to three years, laying about a hundred eggs per nest and up to four nests a season. The eggs incubate seven to eight weeks in warm sand.

Field notes

Every passage carries the number of the source it came from. Nothing here is written from memory.

The Kemp's ridley is the smallest sea turtle — a two-foot, nearly circular shell of grey-green — and the most endangered.Source 1Source 2Source 3

It breaks the family rules twice: it is the only sea turtle that routinely nests in daylight, and the only one that nests in crowds — the arribada.Source 3Source 2

In 1947 a home movie caught the spectacle: an estimated forty thousand females on one Mexican beach in a single day.Source 4

By 1985 there were 702 nests in the entire world — fewer than 250 nesting females.Source 4Source 3

The rescue was bi-national: Mexico and the United States began guarding Rancho Nuevo and, in 1978, building a second colony from scratch.Source 4

For a decade, 22,507 eggs were carried to Texas so hatchlings would imprint on Padre Island sand — and come back to it.Source 5

They came back. Padre Island now records about half of all US Kemp's ridley nests.Source 5

At sea, the biggest threat is fishing bycatch — which is why shrimp trawls in the Gulf must carry turtle excluder devices.Source 3Source 6

Nests climbed to nearly twenty thousand by 2009, then dipped unexpectedly. The recovery is real, and fragile.Source 4

To witness the Kemp's ridley is to hope for crowded beaches again — at noon, in the open, unafraid.Source 2

Cape Cod now rescues hundreds of cold-stunned Kemp's ridleys each fall — an average of 739 a year, five times more than twenty years ago.
