Data and sightings of flatback sea turtles are lacking. The range is limited; they are mostly spotted in Papua New Guinea and around Australia. But they are vulnerable to endangerment because of captivity, fishing, and net entanglement. Other threats to their preservation are diseases, entanglement and ingestion of marine debris and rubbish. The destruction of coral reefs and other feeding habitats also pose problems as well as commercial developments on coastal beaches. Pollution and increase in coastal developments do pose great threats in many areas. These can cause disorientation in hatchlings, leading them away from safe, familiar zones towards unsafe areas.
