- use of terrestrial and marine environments
These life cycle characteristics highlight threats they face;;
- 1/1000 hatchling and young turtles will make it due to predation and environmental impacts (such as plastic and pollutants)
- Genetic viability due to the fact they come back to the same areas they are born.
- migrating over long distances exposes them to disease and open ocean threats and available resources
- Human activity on/in both terrestrial and marine environments such as recreational boating, residential housing, commercial fishing
