Harvesting Protected Species: Sea Turtles 2.3

Name all seven sea turtle species.

Green (Chelonia mydas), Black (Hawaiian form), Leatherback (Dermochelys coriacea), Loggerhead (Caretta caretta), Hawksbill (Eretmochelys imbricata), Olive Ridley (Lepidochelys olivacea), Kemp's Ridley (Lepidochelys kempii), Flatback (Natator depressus).

Why can sea turtle species coexist?

They occupy different feeding niches (e.g., Hawksbill = coral sponges, Green = seagrass, Leatherback = jellyfish).

What historical factors led to overexploitation?

Early explorers captured turtles for fresh meat and eggs—easy to store alive for long voyages.

What modern threats do sea turtles face?

Coastal lighting, dogs, plastic ingestion, and fishing nets.

What is the only legal sea turtle egg harvest site?

Ostional, Costa Rica, during Olive Ridley Arribadas.

Why is Ostional's harvest sustainable?

Locals collect first-wave eggs (which would be destroyed by later nesting), benefiting both the community and turtle populations.

What new problem arose after social media exposure?

Overtourism—visitors crowding nesting beaches and stressing turtles.

Q: What balance is crucial for conservation success?

Economic incentives + ecological protection — like the Ostional example.
