Green tortoise is one of the largest and only herbivore marine tortoises among the various groups. In reality, it is named green turtles for their fat and cartilage greenish color, not for their coats. The local community calls black turtles in the Eastern Pacific a group of green turtles with darker shells. In the tropical and subtropical waters, it finds primarily green turtles. Like other sea turtles, the beaches they have hatched migrate for long distances from feeding grounds. It classifies the Green Turtles as Endangered with over-harvest, adult hunting, fishing gear and nesting beach site destruction.
An average adult weighs between 3 and 4 feet and between 300 and 350 pounds. The shells are dark brown, grey, or olive and are much smaller, yellow to blank. Their bodies have five scutes and four on each side. Green Sea Turtles’ shells have five scutes. Their beak on the lower jaws and two large scales between the eyes is another distinctive feature.
Green sea turtle’s scientific name
The Chelonia mydas Green Sea Turtle is considered a threatened species. It also includes in the International Union for the Conservation of Nature’s Red List for Threatened Species. The CITES forbids foreign trade-in and products of C. mydas among signatory countries. The CITES is an international trade ban. Since the 1900s, worldwide populations of marine turtles have decreased. Because of the negative impacts of human activities such as trade and conventional turtle harvest. Some other activities are habitat alteration and destruction, marine pollution, ship strikes, and diseases.
Green Sea Turtle habitat
Mostly live close to the coast and the islands. Ans also live on bays and shorelines, especially in areas with seagoing beds. In the open ocean, you will seldom see them. Greens nest at intervals of approximately each two years, and the number of nesting females fluctuate widely year after year. 3 to 5 times a season for nests. In each nest, there are, on average, 115 eggs and about 60 days of egg incubation.
The food during her life changes drastically. Eat larvae, young crustaceans, water-based insects, herbs, and algae that are less than 8 to 10 inches long. When green tortoises exceed 8 to 10 inches, they eat mainly seaweed and algae. It is the only adult marine tortoise-only herbivores. Its jaws are thinly tightening, helping it to rip foliage.
You can easily distinguish from other marine turtles, as you have one pair of prefrontal scales (scales before your eyes) and not two teams of other marine turtles. The Head with a twisted jaw is tiny and stumpy. The carapace is restless and has tall, unsurpassed scutes (scales) with only four lateral scutes. The body is almost oval (flattened) and more depressed than Pacific green turtles. There is one noticeable claw in both flippers. The shell colour ranges from pale-to-very-dark green and clear to bright, radiantly striped yellow, brown, and green. The plastrons range from white, dirty white or yellowish to dark grey-blue-green in the Atlantic populations in the Pacific. Hatchlings with a white under and slippery white border are dark brown or nearly black.
For example, the Pacific green turtle (also known as the Black Sea Turtle) has a higher high or vaulted body and appears less round than other green marine turtles in the frontal view. The colour is where the Pacific greens with a dark grey to the black carapace and the hatchlings are dark-brown or black with a thin white margin with white underneath.
Hawaiian green sea turtle
Hawaiian sea turtles are Hawaiian-born. They are the most enormous shelled sea tortoise globally, with four feet of length and over 300 pounds. The Hawaiian green sea turtle is one of the seven varieties of Hawaiian sea turtles. The colour of its shell varies from brown to yellow and light brown to black. The colour is pale yellow in their plastron (lower body). As adults, they eat algae and marine greens, which give them their shared name. Lungs supposed to remain underwater for several hours depending on the size of an animal, with a lung two-thirds as long as its carapace. Five hours was the most extended period ever.
The Hawaiian green marine turtle usually matures at twenty, while some turtles are over 40 until they first develop in a sample. Males are now growing long thick tails, but women’s tails are still short. Females will mate every two years, and after that, over 90% will swim in a distance of almost 600 kilometers (Maui to shoals) to lay their eggs. According to George Balaz, it could take over two months for a Maui woman, who ‘island hop,’ to graze on the sea algae along the way from every island.
Green sea turtle endangered
Like other sea turtles, green Turtles migrate from feeding sites to spawning areas, usually on sandy beaches. Mating occurs in shallow waters along the coast every two to four years. To nest, the women leave the sea and select an area their mothers frequently used to lay their eggs on the same beach. They grab a pit in the sand with flippers and fill it with an assemblage of 100 to 200 shells, cover the hole and go back to the shore. When it goes from nest to sea, it is the most challenging period in the life of a green turtle. Several predators, including crabs and flocks of gulls, greedily preyed on hatchlings during this short scamper.
Green turtles are recorded as an endangered species. For their meat and eggs, they always kill. Incidents involving shipping propellers also diminished its numbers, sinking by fishnet and losing their nesting sites by human intervention.
How long do green sea turtle live
The long-lived green turtles will live for at least seventy or more years. The maturity of the female green tortoises is 25 to 35 years. They migrate every 2 to 5 years and come back to the beach in the general area they hatch decades earlier.
The breeding season starts in late spring in the United States. Man and woman go along migratory paths and off nesting beaches on forage grounds. Green turtles lay approximately 110 eggs per nest, which they nest every two weeks in several months before they leave the nesting area.
The eggs hatch, and hatchlings make their way to the water after approximately two months of incubating in the warm sand. By going from the darkest silhouette of the landing dune or vegetation to crawl to the brightest horizon, Hatchling is orienting towards the sea. This is on the open horizon over the ocean on undeveloped beaches.
