💡 Pro Tips:
1. Sea turtles are ectothermic, meaning they rely on external sources of heat to regulate their body temperature.
2. Sea turtles have a unique ability to navigate by using the Earth’s magnetic field, allowing them to find their way during long migrations.
3. Female sea turtles can lay hundreds of eggs in a single nesting season, but only a small percentage of hatchlings survive to adulthood.
4. Sea turtles have been in existence for millions of years and have survived mass extinction events, including the extinction of dinosaurs.
5. One of the major threats to sea turtle populations is habitat destruction, particularly the destruction of nesting beaches due to coastal development.
