Eggs can drown. #shorts #science #SciShow

Sea turtle embryos breathe through their shells, making oxygen crucial for their development. Turtles lay eggs on land to ensure better oxygen access, but rising sea levels and climate change increase the risk of nest flooding. A study shows that turtle eggs can survive submersion for several hours, indicating their resilience. Understanding these factors can help in developing strategies to protect sea turtles.

Why do sea turtles lay their eggs on land?

• To ensure the eggs get enough oxygen

• To avoid predators in the water

• To keep the eggs dry

• Because the sand is warmer

What is one of the main threats to turtle nests due to climate change?

• Increased predation

• Decreased food supply

• Higher temperatures

• Rising sea levels

How long can turtle eggs typically survive underwater before viability significantly decreases?

• 4 to 5 hours

• 1 to 3 hours

• 8 to 9 hours

• 6 to 7 hours

What percentage of turtle eggs remain viable after being submerged for six hours?

• 50%

• 70%

• 60%

• 40%

Why is it important to understand how sea turtles nest and hatch?

• To increase their population

• To find ways to protect them

• To improve their diet

• To change their nesting habits
