An injured endangered sea turtle has laid six eggs after being brought to a turtle hospital in the Florida Keys.

Hospital administrator Bette Zirkelbach says staff at the in Marathon, Fla., turtle rescue and rehabilitation centre were able to harvest the eggs, and they have been put in an incubator with sand from the U.S. Virgin Islands.

That way, if the eggs hatch, the hawksbill sea turtles will be familiar with their native sand.

Any hatchlings will be taken to the same St. Croix beach where the mother was found Aug. 24 just after Tropical Storm Isaac swept past the Virgin Islands.

Officials say the turtle has deep wounds on both shoulders and might have been hooked by a fisherman and then repeatedly gaffed to remove the fishing gear.

The mother is in guarded condition.
