The loggerhead sea turtle (Caretta caretta) is a species of oceanic turtle distributed throughout the world. It is a marine reptile, belonging to the family Cheloniidae. The average loggerhead measures around 90 cm (35 in) in carapace length when fully grown. The adult loggerhead sea turtle weighs approximately 135 kg (298 lb), with the largest ...
The female remains near shore for the internesting period, which is about one month. Mean clutch size varies throughout its range and decreases with each nesting attempt. [17] A mean clutch size of 116 (30–168 eggs) was observed in Suriname, while nesting females from the eastern Pacific were found to have an average of 105 (74–126 eggs). [11]
Per one study, breeding common snapping turtles were found to average 28.5 cm (11.2 in) in carapace length, 22.5 cm (8.9 in) in plastron length and weigh about 6 kg (13 lb). [ 8 ] Males are larger than females, with almost all weighing in excess of 10 kg (22 lb) being male and quite old, as the species continues to grow throughout life. [ 9 ]
The largest living species of turtle (and fourth-largest reptile) is the leatherback turtle, which can reach over 2.7 m (8 ft 10 in) in length and weigh over 500 kg (1,100 lb). [9] The largest known turtle was Archelon ischyros , a Late Cretaceous sea turtle up to 4.5 m (15 ft) long, 5.25 m (17 ft) wide between the tips of the front flippers ...
It can reach a length of 157 cm (62 in), but usually measures 77 to 100 cm (30 to 39 in). It has a triangular head, a fairly robust cylindrical body, a little flattened dorsoventrally in the posterior region; short and conical tail. The eyes are small; The scales are wide and smooth, all similar except for a slightly elongated ventral row.
Adult specimens exceed 100 cm (39 in) in length and 70 cm (28 in) in width, with weights ranging from 70–100 kg (150–220 lb). [6] A study of large turtles from the Yangtze River reported an average weight of 25 kg (55 lb), although not all specimens were definitively identified as Rafetus. [7]
Older names include "leathery turtle" [7] and "trunk turtle". [16] The common names incorporating "lute" and "luth" compare the seven ridges that run the length of the animal's back to the seven strings on the musical instrument of the same name. [17] But probably more accurately derived from the lute's ribbed back which is in the form of a shell.
C. mouhotii is sometimes treated as the sole species of the monotypic genus Pyxidea. [3] [6] [7] Phylogenetic analysis using mitochondrial DNA has provided evidence that the species is part of the "Cuora group", a monophyletic group of Asian box turtles, and the name Pyxidea should probably be synonymized with Cuora, making the keeled box turtle part of that genus.
