Shift­ing sands: Sea tur­tle nests

BBC Wildlife Magazine - - Sea Turtle Nests -

An adult fe­male will nest 2–10 times each sea­son. A tur­tle nest is 45–55cm deep. It is ex­ca­vated us­ing the back flip­pers and cov­ered again by throw­ing over sand with the front flip­pers. Each nest con­tains 50–200 eggs, de­pend­ing on species. The eggs hatch one and a half to two months later. The most com­mon nester at Anna Maria Is­land is the log­ger­head, be­low.
