🐢 The Life of a Sea Turtle Inside that tiny shell, a miracle slowly unfolds — an embryo forming against the odds. 🗓 Day 1–30: Cells divide, shaping the foundation of a sea turtle. 🗓 Day 30–50: A heartbeat flickers. Flippers take shape. Life begins to move. 🗓 Day 50–60: Growth accelerates. The shell hardens. The hatchling prepares for its grand entrance. Then — under the moonlight — the shell cracks. A tiny turtle emerges, scrambling past crabs and gulls, drawn instinctively toward the surf.
