Green Turtle



GREEN TURTLE



It is estimated that every year about 100,000 green turtles killed in the Indo-Australian archipelago.
 
Physical Description of the green turtle
  
- It has yellow-green or dark brown dark
  
- The shell is oval when viewed from above and head
     
relatively small and blunt
  
- The length is between 80 to 150 cm and
    
weight can reach 132 kg

Ecology and habitat

green turtles are very rarely encountered in temperate waters, but very widely spread in tropical regions close to the continental coast and surrounding islands
.
Development

Age for sexual maturity is uncertain: current estimates of approximately 45 to 50 years. green turtle females migrate in large areas, between feeding and spawning areas, but tend to follow the shoreline compared across the open ocean.

Food

Serupakan adult green turtles sea turtle herbivores. Them were the main food seaweed or algae, which live in tropical waters da subtropics. But his sons assumed omnivore to accelerate the growth of their bodies. Most likely a gradual transition occurs when the turtles reach enough to be able to avoid predators.

Population and Distribution

In coastal areas of Africa, India and Southeast Asia as well as along the coast of Australia and the South Pacific Islands. there are a number of nesting areas and important feeding areas for green sea turtles. They can also be found in the Mediterranean and sometimes in the north to the coastal waters of the UK.Threat* Lost and habitat destruction
      
Uncontrolled development causes damage to beaches that are important to green turtles to lay their eggs. Similarly, the green turtle habitats such as coral reefs for food and marine seagrass continues to damage from sedimentation or destruction by humans.* Taking direct
      
The researchers estimate that every year about 30,000 green turtles captured in Baja, California and more than 50,000 sea turtles killed in Southeast Asia (especially in Bali, Indonesia), and the South Pacific.

      
In many countries, children of sea turtles captured, preserved and sold as souvenirs to tourists. .

* Taking an indirect
      Any idea, green penyi thousands trapped in fishing nets. Sea turtles are reptiles and they breathe with lungs, so that when they fail to reach the sea they died by drowning.
* Disease
      In some islands of Hawaii, nearly 70% of the green turtles stranded, exposed fibropapillomas, cautions that tumors can kill sea turtles. Currently, the cause of the tumor is unknown
.* Natural Predators
      Sea turtles can be issued more than 150 eggs per nest and lay eggs several times during the season, so that more turtles who reached adult levels. The balance between sea turtles and predators can be opposed to the sustainability of sea turtle life when a new predator introduced or if a natural predator suddenly increased as a result of human activity. As happened in the Guianas perteluran coast, is now the main threat to dogs and hatching eggs.
