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 ft) long in the case of the green turtle, the second largest. [5] [12] The skulls of sea turtles have cheek regions that are enclosed in bone.
Another common cause of death is the trapping of the turtles in recreational crab traps, as the turtles are attracted to the same bait as the crabs. [49] The Wetlands Institute estimates that a minimum of 14,000 to 15,000 terrapins drown in crab traps annually set along the New Jersey coast alone. [ 50 ]
Males have larger tails than females do. Their shells are high-domed, and greenish-tan to dark brown in color. The high domes of their shells allow for space for their lungs, which helps them maintain thermoregulation, also known as maintaining internal temperature. [13] Desert tortoises can grow to 10–15 cm (4–6 in) in height.
Sea turtles need to reach the surface to breathe, and therefore many drown once caught. Loggerheads are highly migratory and are very likely to come in contact with a fishery, particularly in shrimp gill nets and long lines. [2] Climate change, also called global warming, refers to the rise in average surface temperatures on Earth.
Turtles can live long lives. The oldest living turtle and land animal is said to be a Seychelles giant tortoise named Jonathan, who turned 187 in 2019. [101] A Galápagos tortoise named Harriet was collected by Charles Darwin in 1835; it died in 2006, having lived for at least 176 years. Most wild turtles do not reach that age.

Like most turtles, they are able to breathe underwater for extended periods of time. They will spend the colder months underwater, buried in the mud or sand in a state of dormancy. [6] When bothered, spiny softshell turtles will extend their long necks and snap viciously at their attacker, inflicting a painful bite.
Cold-stunned sea turtles may float to the surface and be further exposed to cold temperatures, which can cause them to drown. [1] A water temperature threshold of 8 [2] –10 °C [3] has been associated with mass turtle stunning events. After cold-stunning has taken place, there is only a very short period of time when sea turtles can be safely ...
