Identifying turtles

7 different types of turtles





  • strong paddle like front flippers for power and speed. Rear flippers act like rudders
  • strong breath capabilities
  • ectothermic
  • salt glands-excrete salt near eye
  • beaks-species specific and suited to diet-serrated and clipping, thin and slicing,cusped thick and crushing



  • adult females are the only turtles that come to land to lay eggs generally 2-6 clutches per season with around 1000 eggs in each clutch
  • late maturation -reach sexual maturity at age 15-20 years
  • high mortality of hatchlings
  • strong fidelity to breeding areas (they will go back to breed and lay where they were born.
  • migrating over long distances
  • 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
