The hawksbill turtle is a reptile belonging to the family Turtles and the genus hawksbill. The hawksbill turtle inhabits tropical and subtropical oceans. Most of the time in their lives, hawksbill turtles live alone, and they only meet for mating. The hawksbill turtle has strong migratory ability and a wide range of living environments. The hawksbill mainly feeds on coral reefs and also preys on some crustaceans, algae, and fish. Distributed in vast sea areas, mainly found in tropical regions of the Atlantic and Pacific Oceans. The crawling speed of hawksbill turtles is slow and they are easily hunted and killed by humans. The beaches that serve as nesting areas for hawksbill turtles are often destroyed, and the required years for sexual maturity are long, resulting in a low reproductive rate. Therefore, the population is extremely difficult to recover.
