Final answer:
The Hawksbill turtle is endangered and recognized by its hawk-like head shape. It's critically dependent on undeveloped beaches for nesting, such as Playa Grande.
Step-by-step explanation:
The endangered sea turtle that has a head resembling a hawk is the Hawksbill turtle. The Hawksbill turtle is known for its pointed beak and beautifully patterned shell, which unfortunately has made it a target for illegal wildlife trade. This has contributed significantly to its endangered status, along with habitat loss and ocean pollution. Its unique beak shape helps it to extract sponges and other invertebrates from tight spaces in coral reefs, an adaptation that has evolved through natural selection. Like other sea turtles, Hawksbill turtles use sandy beaches for egg laying, making undeveloped beaches like Playa Grande critical for their survival due to reduced human disturbance and predation.
