Feminisation of Red Sea Turtles.

8 December 2020.


A study found an increase in the number of female turtles in the Red Sea, due to increased sea temperature caused by ‘anthropogenic-climate-change’. The research team from King Abdullah University of Science and Technology, Saudi Arabia, investigated five different habitats of hawksbill and green turtles.


  • A temperature of ’29°C’ is crucial to maintain balance between male and female turtles. However, studies temperate limit which is causing ‘Feminisation’ of turtles.
  •  Above this temperature, the turtle hatchlings will predominantly be female.
  •  The researchers during the study found that the temperature at four out of the selected five sites exceeded 29.2 degrees Celsius.
