Giant Turtles: How Much Weight Can They Carry?

The weight of a turtle varies depending on its species and type. Some turtles can weigh as little as 5 ounces (142 grams) at birth, while others can grow to weigh several hundred pounds. The leatherback sea turtle is the largest of all living turtles and the heaviest non-crocodilian reptile, weighing between 500 and 2,000 pounds (225 to 900 kilograms). Sea turtles, such as the Kemp's Ridley, weigh between 80 and 100 pounds (36 to 45 kilograms). Other common pet turtle species, like the red-eared slider, weigh approximately 6.61 pounds (3 kilograms) when fully mature.

The leatherback sea turtle is the heaviest turtle, weighing up to 2,000 lbs

The leatherback sea turtle (Dermochelys coriacea) is the heaviest turtle species in the world. It is also the largest of all living turtles, reaching lengths of up to 2.7 metres (8 ft 10 in) and weighing up to 500 kilograms (1,100 lbs). The largest leatherback sea turtle ever recorded weighed 916 kilograms (2,019 lbs).

Leatherback sea turtles are unique among modern sea turtles in that they lack a bony shell. Instead, their carapace is covered by oily flesh and flexible, leather-like skin, which gives them their name. Seven distinct ridges rise from the turtle's back, crossing from the cranial to caudal margin. This soft, leathery skin covers osteoderms—bone-like hydroxyapatite/collagen tissue with jagged edges, also known as 'teeth'. The osteoderms are connected by a zig-zag configuration of interpenetrating extremities called sutures, which provide flexibility to the carapace and enable in-plane and out-of-plane movement between osteoderms. This flexibility is important as the lungs, and thus the carapace, expand when taking in air and contract when diving to great depths.

Leatherback sea turtles are the heaviest non-crocodilian reptiles and the only living species in the genus Dermochelys and family Dermochelyidae. They are found in tropical and temperate marine waters worldwide, including the Atlantic, Pacific, and Indian Oceans, as well as the Mediterranean Sea. They live off both the east and west coasts of the United States, as well as Puerto Rico, the Virgin Islands, and Hawaii.

Leatherback sea turtles have a distinctive teardrop-shaped body and large front flippers that power their swimming. They are the fastest-moving non-avian reptiles, capable of reaching speeds of 35.28 kilometres per hour (21.92 miles per hour) in the water. They are also one of the deepest-diving marine animals, with individuals recorded diving to depths of up to 1,280 metres (4,200 feet).

The diet of leatherback sea turtles consists primarily of jellyfish, which they pursue to great depths. They also feed on other soft-bodied organisms, such as siphonophores, salps, pyrosomas, squid, small crustaceans, fish, sea urchins, snails, seagrasses, and algae. Their throat is adapted to their diet, with downward-pointing spines that allow jellyfish to be swallowed but prevent them from coming back up.

Leatherback sea turtles are federally listed as endangered. Their primary threats include human activities such as poaching of eggs and adults, entanglement in fishing gear, and ingestion of plastic marine litter. Climate change also poses a significant threat to their nesting beaches and long-term reproductive success.

The smallest species of turtle in the world is the speckled padloper tortoise, with females reaching under 4 inches in length

Turtles vary greatly in size depending on their species, with some weighing less than a penny at birth and others growing to several hundred pounds. The smallest species of turtle in the world is the speckled padloper tortoise, with females reaching under 4 inches in length. Also known as the speckled dwarf tortoise (Chersobius signatus), this species is endemic to a small area in Little Namaqualand, South Africa. The weight of the speckled dwarf tortoise ranges from 95 to 165 grams, with females reaching up to almost 10 cm in length and males only growing to 6-8 cm. The species is distinguished by its orange-brown shell covered in hundreds of black spots, as well as the five toes on its front feet.

Speckled padloper tortoises are not considered ideal pets due to their unique feeding requirements. In the wild, they live among rocky outcrops and feed on a variety of plant species, particularly small succulents that grow between rocks. They are most active in the early mornings during autumn and spring, which is their breeding season. After mating, female speckled padlopers create nests in damp soil between the rocks, typically producing one large egg at a time.

The speckled dwarf tortoise is considered near threatened by the IUCN Red List, facing threats such as vehicular traffic, habitat destruction, and poaching for the pet trade. Their populations have declined significantly in recent years, with a 66% decrease in resident populations from 2000 to 2015.

When considering a pet turtle, it is important to research the specific species' natural habitat and requirements, as well as provide ample space for the turtle to grow and thrive.

The largest freshwater turtle is the alligator snapper, weighing close to 100 lbs

Turtles vary greatly in size depending on their species and type. While some turtles can weigh less than a penny at birth, others can grow to weigh several hundred pounds. The weight of a turtle can start from 3 to 4 pounds and can go up to 100 pounds. The largest sea turtle, the leatherback, weighs over 2000 lbs, while the smallest sea turtle, Kemp's Ridley, weighs 80 to 100 lbs.

Among freshwater turtles, the alligator snapper is the largest in North America and one of the largest in the world. It is also known as Macrochelys temminckii and is native to freshwater habitats in the United States. The alligator snapping turtle is characterised by its large, heavy head, and long, thick shell with three dorsal ridges of large scales, giving it a primitive, dinosaur-like appearance. Its shell length can range from 35 to 80.8 cm, and it can weigh anywhere from 8.4 to 80 kg. While males typically weigh around 175 pounds, they have been known to exceed 220 pounds. The much smaller females weigh up to around 50 pounds.

The alligator snapping turtle is an opportunistic feeder, preying on fish, mollusks, carrion, amphibians, snakes, snails, worms, and even small alligators. It is also known to eat aquatic plants. They are most active at night, employing a unique hunting technique by luring prey with a bright-red, worm-shaped piece of flesh on their tongue. During the day, they often lay motionless in murky waters, keeping their mouths open to attract unsuspecting prey.

The alligator snapping turtle is a vulnerable species, facing threats from unregulated harvesting, habitat loss, and the exotic animal trade. It is now protected by state law in several US states, including Indiana, Illinois, Kentucky, and Missouri, and is listed as a threatened species.
