Teenagers Daniel and Martin Improve Leatherback Turtle Research in Costa Rica

Teenagers' Costa Rica Expedition

• 💡 Daniel and Martin, 10th-grade students, traveled to Costa Rica in 2015 for a biology class field trip.
• 🎯 Their goal was to learn about endangered leatherback turtles and assist marine biologists at a conservation preserve.
• ⚡ They unexpectedly discovered a way to improve research for a biologist at the station.

Hands-On Marine Biology

• 🔬 Students lived like marine biologists, assisting with ongoing research missions at the station.
• ✅ Tasks included counting turtles on beaches for censuses and tracking hatching eggs at known nests.
• 🧠 They learned to identify sea turtle species and understand their habits and life cycles.

Leatherback Turtle Biology

• 🐢 Leatherbacks are among the oldest reptiles, originating about 150 million years ago in the late Jurassic period.
• 🌊 They are the largest sea turtles, migrating vast distances and growing up to 9 feet long and weighing 1,500 pounds.
• 🍽️ Their diet primarily consists of jellyfish, consuming over 400 pounds daily, and they also graze on seagrass.

Unique Adaptations & Ecological Role

• 🧬 Unlike other sea turtles, leatherbacks have a tough, leathery skin instead of a hard shell, allowing them to dive up to 4,000 feet deep.
• 🌬️ Their flexible shells compress during deep dives, enabling them to withstand immense water pressure.
• 🌱 Leatherbacks play a key role in ocean and land ecosystems by bringing nutrients to nesting beaches and balancing food webs.

Ancient Survival & Conservation

• ⏳ The ancestors of leatherbacks survived the KT event 65 million years ago, a mass extinction that wiped out dinosaurs.
• ⚠️ All great sea turtle species are currently at risk of extinction, with only one turtle remaining for every thousand that once existed.
• 🌍 Marine biologists aim to preserve these ancient creatures through increased knowledge and informed conservation efforts.
