Sea Turtle Nesting and Survival

Sea turtle eggs are encased in shells but can drown if submerged in water. Turtles lay eggs on land to ensure oxygen access, as more oxygen leads to healthier hatchlings. Rising sea levels and climate change increase nest flooding, threatening egg survival. A 2015 study showed that eggs can survive short-term submersion, but prolonged exposure reduces viability. Understanding nesting and hatching can aid in protecting sea turtles.

Why do sea turtles lay their eggs on land?

• To prevent the eggs from being washed away

• To ensure the eggs get enough oxygen

• To keep the eggs warm

• To avoid predators in the water

What is the main reason sea turtle embryos can drown in their eggs?

• Excessive heat

• Predator attacks

• Inadequate oxygen exchange

• Lack of food

What is a major threat to sea turtle nests due to climate change?

• Increased predation

• Higher temperatures

• Rising sea levels

• Decreased food supply

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

• 6 to 7 hours

• 1 to 3 hours

• 4 to 5 hours

• 8 to 9 hours

What percentage of sea turtle eggs survive after being submerged for 1 to 3 hours?

• 50%

• 70%

• 90%

• 100%

What can help us protect sea turtle nests better?

• Observing their social behavior

• Learning about their nesting and hatching

• Studying their migration patterns

• Understanding their diet
