In the research it is found that the algae which is living with the coral generates a compound that is transferred to the coral and then it converts it in a form similar to sunscreen which protects the coral and the algae from the harmful UV rays.
Both the coral and the algae gets protection from the UV rays damage and also it is found that the fish which feeds on the coral also gets the advantage of the sunscreen and also this process is continued in the food chain.
The researchers also found that the coral and algae have the capacity to defend themselves from the harmful UV rays in tropical climates. So this can get a conclusion that people can get internal protection of their skin from sun by the use of this sunscreen.
'Once we recreate the compounds we can put them into a lotion and test them on skin,' says Dr Long.
Now the researchers are not much sure about how much protection it will give from the sun. So after testing they might be able to calculate the effectiveness of the sunscreen.
