The subspecific classification of the loggerhead sea turtle is debated, but most authors consider it a single polymorphic species. [12] Molecular genetics has confirmed hybridization of the loggerhead sea turtle with the Kemp's ridley sea turtle, hawksbill sea turtle, and green sea turtles. The extent of natural hybridization is not yet ...
In contrast to their earth-bound relatives, tortoises, sea turtles do not have the ability to retract their heads into their shells. Their plastron, which is the bony plate making up the underside of a turtle or tortoise's shell, is comparably more reduced from other turtle species and is connected to the top part of the shell by ligaments without a hinge separating the pectoral and abdominal ...
The leatherback sea turtle is the largest sea turtle, reaching 1.4 to more than 1.8 m (4.6 to 5.9 ft) in length and weighing between 300 and 640 kg (661 to 1,411 lbs). [11] Other sea turtle species are smaller, ranging from as little as 60 cm (2 ft) long in the case of the Kemp's ridley, which is the smallest sea turtle species, to 120 cm (3.9 ...
The growth rate of C. testudinaria follows a non-linear growth pattern where rate of increase in length slows with age. [3] Applying a von Bertalanffy growth model to the population suggests that the maximum achievable size of C. testudinaria on loggerhead turtles in the wild is approximately 70 mm (2.8 in) in rostro-carinal length.

[16] [21] Turtle scutes are usually structured like mosaic tiles, but some species, like the hawksbill sea turtle, have overlapping scutes on the carapace. [16] The shapes of turtle shells vary with the adaptations of the individual species, and sometimes with sex. Land-dwelling turtles are more dome-shaped, which appears to make them more ...
A rehabilitated sea turtle was released back into the Atlantic Ocean from a Florida beach Wednesday morning. Willow, a subadult loggerhead, was set free in the area behind the Loggerhead ...

Hawksbill sea turtle (Eretmochelys imbricata) Sea turtles: there are seven extant species of sea turtles, which live mostly along the tropical and subtropical coastlines, though some do migrate long distances and have been known to travel as far north as Scandinavia. Sea turtles are largely solitary animals, though some do form large, though ...
