She Buried Her Eggs for 90 Days — Then She Heard Them Calling | Crocodile Birth Documentary

🐊 SHE BURIED HER EGGS FOR 90 DAYS — THEN SHE HEARD THEM CALLING | Crocodile Birth Documentary Witness one of the most extraordinary events in the natural world — a Nile crocodile mother guarding her eggs for 90 days, and the moment she hears her hatchlings calling from beneath the sand. From egg to apex predator, this is the complete crocodile life cycle documentary, produced in BBC Planet Earth style. ⏱️ TIMESTAMPS 0:00 — Introduction: The eternal survivor 0:30 — Nesting: Female selects site and lays 40–80 eggs 1:00 — 90 days of incubation: Temperature determines sex 1:45 — The most remarkable fact: babies call from inside the eggs 1:50 — Mother excavates the nest with her jaws 2:35 — Hatching: The egg caruncle breaks the leathery shell 3:00 — The mouth carry: babies transported to water in mother's jaws 3:45 — First year survival: only 1 in 10 reaches adulthood 4:30 — The rise to apex predator: 20 years to full size 5:00 — Conservation: population decline and threats 5:30 — Outro: 200 million years unchanged 🔬 SHOCKING FACTS IN THIS VIDEO ✅ A female crocodile can hear her eggs chirping underground — she excavates immediately ✅ Temperature determines the sex: below 30°C = all female, above 32°C = all male ✅ The mother uses her massive jaws — capable of crushing bone — to carry hatchlings gently ✅ Crocodile eggs have leathery shells, not hard shells like birds ✅ Only 1 in 10 hatchlings survives its first year ✅ Baby crocodiles are born with a full set of teeth and are immediately capable of hunting ✅ A crocodile's bite force is 5,000 psi — the strongest of any living animal ✅ Nile crocodiles have lived essentially unchanged for 200 million years ✅ A crocodile can live 70–100 years ✅ The mother guards her nest for the entire 90-day incubation — one of the longest in reptiles 📖 WHAT IS TEMPERATURE-DEPENDENT SEX DETERMINATION? Crocodiles do not have sex chromosomes like mammals. Instead, the sex of each hatchling is determined by the temperature inside the nest during a critical window of incubation. Below 30°C produces all females. Above 32°C produces all males. This phenomenon, called TSD (Temperature-Dependent Sex Determination), means climate change directly threatens crocodile sex ratios — a critical conservation concern. 🐊 SPECIES INFORMATION Featured species: Nile Crocodile (Crocodylus niloticus) Order: Crocodilia | Family: Crocodylidae Incubation: 80–90 days | Clutch: 40–80 eggs Hatchling length: 28–30 cm | Adult length: up to 6 metres Adult weight: up to 700 kg | Bite force: 5,000 psi Lifespan: 70–100 years | Speed: 35 km/h on land, faster in water Conservation status: Least Concern (but heavily threatened in some regions) Population: Estimated 250,000–500,000 wild individuals 🎬 ABOUT BORN WILD Born Wild documents the complete life cycles of Earth's most extraordinary animals — from first breath to apex predator.
