Community Messages  & Key Facts on Sea Turtles

  • Sea Turtles (Chelonioidea) are reptiles found in all the world’s oceans except the Arctic Ocean.
  • Sea Turtles play key roles in the two ecosystems that are critical to them as well as to humans – 1) the oceans and 2) beaches/dumes
  • They can live up to 189 years
  • If sea turtles were to become extinct, the negative impact on beaches and the oceans would potentially be significant
  • Some species travel between oceans like the Loggerhead and Leatherback turtles.
  • There are 7 types of sea turtles: 1) KEMP’S RIDLEY, 2) FLATBACK, 3) GREEN, 4) OLIVE RIDLEY, 5) LOGGERHEAD, 6) HAWKSBILL AND 7) LEATHERBACK.
  • All but the Leatherback are in the family of Chelonioidea;
  • Leatherbacks belongs to the family of Dermochelyidae and is only member
  • They are highly sensitive to the Earth’s magnetic field and use it to navigate
  • Papua New Guinea is the last remaining nesting site for the endangered Pacific Leatherback Turtles.
  • Scientists predict that Pacific Leatherbacks Turtles could be extinct in 20 years time, at the current harvest rate (by-catch)
  • Based on community testimony we know that the population has decreased since the 1990s
  • Tri-national MOU signed between PNG, Solomon Islands and Indonesia in August 2006 to protect Leatherback Turtles
  • Travel at the distance of 12,774 miles 20,558 km across the Pacific the longest recorded migration of any sea vertebrates
  • Less than 5,000 nesting leatherbacks exist in the Pacific Ocean today and that is a 95 percent drop from 1980
  • They are the deepest diving sea turtles on earth
  • They weigh more than 92 bags of 10kg rice or 916 kilograms
  • They can reach the size of a cab or 270 cm (2.7 meters)
  • Leatherbacks have been in existence for more than 100 million years
  • Marine Debris is affecting reproduction and nesting behaviors (plastic waste is lethal to leatherbacks, plastic bags) US dumping debris in our ocean is effecting our resources
  • Sea-bed mining and dumping of terrestrial slurry is potentially harmful to the habitat and migratory routes (plumes of mining may harm everything in the ocean and humans)
  • Another threat is poaching
  • Unintentional capture and drowning by commercial fishing boats (especially shrimp trawlers)
  • Commercial developments
  • Potential for climate change
  • Fisheries/overfishing using longline and gillnets
  • Pollution
  • Rising sea-levels are eroding the nesting sites and diverting the turtles from traditional sites and moving them to other sites
