Sea Turtles Species

 
According to scientific research, it is estimated that there are eight species of sea turtles in the world. Five of these species are in the habit of frequenting the beach stretches of the South Coast of Sri Lanka.
 

Five kinds of sea turtles live in Indian Ocean.

 
  1. Hawksbill turtle
  2. Green turtle
  3. Olive Ridley turtle 
  4. Loggerhead turtle
  5. Leatherback turtle
 
All of which are found around Sri lanka  considered Vulnerable, Endangered, or Critically Endangered by the IUCN Red List of Threatened Species. Primary drivers of population declines have included incidental capture of sea turtles in fishing gear (i.e. bycatch) and human consumption of turtle eggs and meat.
