Fun facts

  • GeneralThe most threatened sea turtle; it nests en masse — an arribada — on a single beach in Tamaulipas.
  • In 1947 an arribada of more than forty thousand females nesting in a single day at Rancho Nuevo was filmed by chance: when that footage was rediscovered in the 1960s, the population had fallen so far that it served both to measure the collapse and to launch the recovery programme.
  • It is the only sea turtle that nests by day and in synchronised arribadas, behaviour that swamps predators but that left it extremely vulnerable to egg collecting.
  • The binational programme between Mexico and the United States that has protected the beaches of Tamaulipas since 1978 is one of the longest continuously running marine wildlife conservation projects in the world.
