Along the shores of the Balochistan and Sindh beaches, five endangered sea turtle species are still surviving. They are the Green Sea turtles, Hawksbill turtles, Loggerhead turtles, Olive Ridley turtles and Leatherback turtles.
Green Turtles breed in different countries in different season generally from July to November. In Pakistan, Green Turtle nests for eggs on Sandspit and Hawksbay beaches throughout the year with a remarkable apex from September to January. A breeding female nests three to four times during the season. Every year, an average of 800 nests have been observed at beaches of Karachi. Coastal areas of Balochistan are also believed to support a large number of Green Turtles.
The Green Turtle species is facing various challenges in order to last in marine world. The threats to its populations include several factors from its low growth rate to other environmental constraints. The rate of successful hatching from eggs in an ideal situation and habitat is just 55 percent. The eggs buried in sand are also foraged by crabs, crows, eagle and stray dogs etc. The survival rate of hatchlings in sea is as low as 0.1 percent, since a large number of baby turtles are eaten by fish and other under water creatures. Many large and small turtles are also trapped in nets of fish-trawlers.
There is another perilous fact about newly born turtles that they start crawling towards light. Those who have been hatched in night hours will move toward any hut with lights, instead of going into the sea. There is a risk of being consumed by dogs as well as quashing by any vehicle for those little turtles.
