What physiological challenge confronts the loggerhead sea turtle (Caretta caretta) nesting along Mediterranean beaches?
Answer and explanation
Correct answer: D. artificial light disorienting hatchlings
- Step 1: Caretta caretta females lay their eggs in sandy beaches, particularly in the Ionian islands like Zakynthos. Upon emerging at night, hatchlings navigate toward the brightest natural horizon (the sea), but coastal resort lights disorient and kill them. Answer: artificial light disorienting hatchlings. Why not the others: "freezing winter maritime blizzards" falsely assumes arctic conditions during the warm Mediterranean summer breeding season; "widespread hypoxic open ocean oxygen dead zones" relates to enclosed eutrophic estuaries rather than high-energy coastal nesting beaches; "massive freshwater lake floods" confuses maritime nesting beaches with inland lacustrine freshwater habitats.
