- They are one of the oldest living reptile species, with ancestors like the massive Archelon that roamed the oceans during the Late Cretaceous period.
Evolution and Adaptations
- Sea turtles have evolved to become streamlined, efficient swimmers over millions of years.
- They have developed specialized features, such as flippers that propel them through the water and streamlined shells that help them glide effortlessly through the waves.
Life Cycle
- Female sea turtles lay eggs on sandy beaches, which hatch into tiny hatchlings that make a perilous journey to the ocean.
- Young turtles spend several years drifting in the open ocean, feeding on marine life and growing into adulthood.
- Mature sea turtles return to their natal beaches to lay eggs, using their ability to sense the Earth's magnetic field to navigate.
Challenges Facing Sea Turtles
- Habitat loss, pollution, and bycatch are major threats to sea turtles.
- All seven species of sea turtles are currently classified as either threatened or endangered.
Importance of Sea Turtles
- Sea turtles play a vital role in the health of our oceans and marine ecosystems.
- They help regulate prey populations, such as jellyfish and seagrass, and serve as indicators of ocean health.
- They hold cultural and symbolic value for many societies around the world.
Conservation Efforts
- Organizations are working to raise awareness, enact protective legislation, and support research and rehabilitation programs to protect sea turtles and their habitats.
