What is Green Turtle?
Green Turtle (Chelonia mydas) is one of the 3
species of sea turtles found in Hong Kong waters
and so far has been the only species known to
breed locally. The feet are modified into
flippers. Length of Carapace70-150cmWeighs200kg

Live of Green Turtle
  • Like other sea turtles, Green Turtles return to
    nest at the beach where they were hatched.
  • During their breeding season, the turtles migrate
    from their feeding ground to mate in shallow
    waters off their nesting beaches.
  • The females come ashore two or more times a
    season on an average of every 3 years to lay eggs
    in a nest cavity on the beaches..

Why Green Turtles Disappear?
  • Green Turtles invariably return to their natal
    beach to nest.
  • Any development and human activities that will
    change the natural environment of the nesting
    site and/or cause obstructions to their migratory
    route would wipe out the local population.
  • Illumination and noise produced behind the
    nesting beach as a result of development,
    recreational activities or roads will deter the
    females from coming ashore to nest.
  • Intensive illumination will disorient the
    hatchlings from going into the sea, causing
    deaths to the hatchlings.

5
Why Green Turtles cant reproduction?
  • Debris washed ashore hinders movement of nesting
    females and hatchlings.
  • Boating and fishing activities in the sea area
    during the breeding season cause disturbance to
    their mating activity.
  • Accidentally caught in nets and hit by
    propellers.
  • Green Turtles normally have a very low survival
    rate due to predation and natural mortality and
    mature turtles only lay eggs every two to three
    years on the average.
  • Poaching of eggs will cause severe population
    decline.

The responsibility of government
  • Green Turtle is a highly endangered species
    listed under the Appendix I of the Convention on
    International Trade in Endangered Species of Wild
    Fauna and Flora (CITES).
  • It is protected under the Wild Animals
    Protection Ordinance Cap.170. Under the
    Ordinance, no person shall hunt or wilfully
    disturb any protected wild animal, or have in his
    possession of any hunting appliance or protected
    wild animal taken in Hong Kong.
  • No person shall take, remove, injure, destroy or
    wilfully disturb a nest or egg of any protected
    wild animal.
