The loggerhead sea turtle (Caretta caretta) is a marine reptile in the family Cheloniidae found in the Atlantic, Pacific, and Indian Oceans and the Mediterranean Sea. Adults average about 90 cm carapace length and roughly 135 kg in weight, with the largest individuals near 200 kg. Skin color ranges from yellow to brown and the shell is typically reddish brown. No external sex differences are evident until adulthood, when males develop thicker tails and shorter plastrons than females. Loggerheads spend most of their lives in saltwater and estuarine habitats; females come ashore briefly to lay eggs. They reach sexual maturity within about 17–33 years and have been reported to live roughly 47–67 years. Loggerheads are omnivorous and feed mainly on bottom-dwelling invertebrates, using their large, powerful jaws to break apart prey. Eggs and young are vulnerable to numerous predators, while adult turtles are largely preyed upon only by large marine animals such as large sharks.
Loggerheads are considered Vulnerable. Key conservation measures include legal protections, restrictions on international trade, use of turtle excluder devices in trawl fisheries, and efforts to protect and restore nesting beaches; international cooperation is needed due to their wide-ranging movements.
Widely distributed across major oceans and the Mediterranean; spends most of life in saltwater and estuarine habitats and nests on beaches, with females coming ashore to lay eggs.

Amenazas principales
Fishing gear and bycatch
Untended fishing gear and capture in trawls cause many deaths; turtles can suffocate or become trapped without escape routes.
Loss of nesting habitat
Coastal development and loss of suitable nesting beaches reduce available nesting sites and contribute to population declines.
Human disturbance and artificial lighting
Coastal lighting and nearby housing developments can disorient hatchlings and disturb nesting females.
Predation of eggs and hatchlings
Eggs and young are vulnerable to numerous terrestrial and marine predators, including introduced exotic predators on nesting beaches.
Protecciones y controles
CITES Appendix I
Commercial international trade of loggerheads or derived products is prohibited under CITES Appendix I.
U.S. Endangered Species Act
Nine distinct population segments are protected under the ESA, with four listed as threatened and five as endangered.
Turtle Excluder Devices
Turtle excluder devices have been implemented in trawl fisheries to reduce mortality by providing escape routes.
