Sea Turtles from Madagascar

 

Madagascar, due to its geographical location in the Indian Ocean, is also a passage for several sea turtles and sometimes wandering turtles.

We can name five of them:

 The Caretta caretta

Known as the Loggerhead turtle, this sea turtle weighs with weights of up to 200 kg for 112 cm in the largest specimens.

Antalya'da 10 kişiyi caretta caretta ısırdı - Son Dakika Haberleri ...It is worth noting that females are larger than males, as males have a longer tail that extends more than 25 cm beyond the back of the shell.

Their jaws are thick, their reddish-brown color, and their two claws on each flipper allow us to easily distinguish them from other sea turtle species.

In addition, their scales do not overlap, unlike other species such as the loggerhead turtle.

The first rib scale is in contact with the nucleus.

Distribution and Habitat

There are two subspecies:

Caretta caretta gigas found in the Pacific and Indian Oceans.

Caretta caretta found in the Atlantic Ocean.

The loggerhead sea turtles of the species Caretta caretta thrive in temperate waters and migrate according to the season. These turtles live near coasts, reefs, and brackish water lagoons.

Lifestyle of Caretta caretta

Initially, young turtles are omnivores and mainly feed on sponges, jellyfish, crustaceans, fish eggs, and algae from the Sargasso Sea.

İnternetten caretta caretta kabuğundan tespih satışı - Son Dakika ... Adult sea turtles feed on crabs and shellfish, which they can easily crush with their powerful beaks. They also consume jellyfish, mollusks, squids, fish, and carrion.

The breeding season occurs between May and October, approximately every two to three years.

Each female lays 4 to 6 clutches of about 120 eggs per nest per season, with a two-week interval between each laying.

The diameter of the eggs ranges from 3.5 cm to 5 cm, and the incubation period is about two months.

The gender of the hatchlings is determined by the incubation temperature. Higher temperatures result in more female hatchlings.

The young animals are.

The Green Turtle or Chelonya midas

It is called the “green turtle” not because of its color (which is not green), but because of the color of its fat, which is green. It is the second largest species of sea turtle.

Green turtle (Chelonia mydas) - NatureFiji - MareqetiVitiThe first is the Leatherback Turtle (Dermochelys coriacea), which can reach up to 1 ton, and the second is the Green Turtle (Chelonia mydas), which can reach up to 250 kg in adulthood.

Species Description

Turtle shell-It is difficult to determine the color of individuals of this species. describes the color variation of turtles as they age, with differences in hue even after reaching adulthood.

When hatching from the egg, the baby turtle has a black carapace and a white plastron. Between the ages of two and fifteen, the shell color changes to brown on the back and beige on the plastron.

From the age of 15, their color changes again to a much darker shade, ranging from dark brown to a very dark olive green, sometimes even grayish. The head is relatively small and

Has a pair of prefrontal and four postocular scales.

The upper side is arched and oval in shape. It has four rib scales, four (sometimes five) vertebral scales, a pygal scale, and a divided supracaudal scale. The scales are “joined”, meaning glued together, unlike the Loggerhead sea turtle, whose scales overlap like the tiles on a roof.

Males can be distinguished from females by the size of the tail, which is longer and thicker in males due to the presence of the penis inside, and by the presence of a claw on the front flippers of males, allowing them to grip the female’s back during mating.

Female turtles to catch.

The Green Sea Turtle, unlike land turtles, does not have vocal cords.

The Hawksbill Sea Turtle, Eretmochelys imbricata

It is a turtle that you may have heard of before, called the Hawksbill Sea Turtle. It is one of the eight species of sea turtles that exist today, and the only one of the genus Eretmochelys.

Its range is almost global, as it is found in all oceans. It has two subspecies: E.imbricata imbricata and E.imbricata bissa.

The Hawksbill Sea Turtle was originally described in 1766 by Carl Linnaeus as Testudo imbricata.

At the beginning of the 19th century, the systematics were refined, sea turtles were identified as common features.

Recognized and grouped into common taxa.

A new genus Eretmochelys (from the Greek: eretmo, oar and chelys, turtle) was proposed in 1843 by the Austrian zoologist Leopold Fitzinger.

Description of Eretmochelys imbricata

Its shell is very easy to distinguish from other species. It is called hawksbill turtle because its scales overlap in such a way that they resemble the tiles on a house roof.

Only in some old specimens, this feature is no longer valid, as the upper side tends to become smooth over time.

There are four pairs of ribs and five vertebral scutes, which in young specimens may exhibit a slight keel. Another Characteristic of this turtle is that it has posterior serrated edges.

The shell of the Eretmochelys imbricata is orange-brown to black in color, with an irregular combination of light and dark stripes with yellow or red spots.

The plastron is yellow, the post-anal scales are the same color with black spots. The fins are brown on the top and yellow on the bottom.

On the head, it has four prefrontal scales and a particularly long hooked beak.

Eretmochelys imbricata males are characterized by a lighter pigmentation and, like. The Olive Ridley sea turtle, also known as Lepidochelys olivacea, is one of the most widely distributed sea turtle species in the world. It is characterized by a concave plastron, longer claws, and a thicker tail. In terms of size, it can reach lengths between 60 cm and 1.20 m and weigh between 60 kg and 90 kg.

The Leatherback sea turtle, or Dermochelys coriacea, is the largest of all sea turtle species. It is known for its massive size and unique characteristics. Check out this image of a Leatherback Turtle (Dermochelys coriacea) for more information.

The leatherback sea turtle, also known as the leather turtle in French, is a well-known species. We often hear about it because its diet consists of jellyfish, which it mistakes for the plastic bags we discard and end up in the sea or ocean.

Description of the leatherback sea turtle

It is the largest chelonian in the world, as this species can reach a length of 3 meters and weigh up to a ton.

It has the peculiarity of not having a bony shell like other sea turtles. Its shell is made of a thin skin covering a thick layer of fat and numerous tiny osteoderms, giving it a leathery appearance.

Sea Turtle sind weltweit, mit Populationen in den tropischen und gemäßigten Gewässern der Weltmeere. Sie bevorzugen offene Ozeane, sind aber auch in Küstennähe zu finden.

Die Lederschildkröte ernährt sich hauptsächlich von Quallen, obwohl sie auch andere wirbellose Tiere wie Krill und Tintenfische frisst. Sie sind eine gefährdete Art, hauptsächlich aufgrund von menschlichen Aktivitäten wie Beifang, Verschmutzung und Lebensraumverlust.

Sea Turtle

The leatherback turtle prefers to live in the oceans, although some individuals currently live in the Mediterranean, for example. There are three major populations distributed around the globe (Indian Ocean, Atlantic Ocean, and Pacific Ocean) in tropical and subtropical areas. It is the only sea turtle that can venture into the cold waters of the north and south of the Earth. Dives to depths of more than 1300 m have been recorded.

Behavior of Dermochelys coriacea

It is a turtle that migrates according to the populations of jellyfish and other animals that make up the majority of its diet. It despises. Consumption of crustaceans, fish, carrion, and sometimes even algae is not uncommon.

The presence of plastic bags in the seas and oceans leads to an increase in mortality. In fact, turtles mistake plastic bags for jellyfish, which hinders their digestive systems.

Little is known about their lifestyle, except that they travel long distances and spend their days in deep water and nights closer to the surface. However, they must surface to breathe approximately every hour.

Females lay their eggs in locations attached to them (always the The average number of eggs laid by sea turtles is 2 to 3, but up to 5 can be laid at intervals of 10 to 15 days. Each clutch consists of 100 to 200 eggs with a diameter of 5 cm and a weight of 40 to 50 grams.

Incubation lasts 60 to 70 days, and the newborns emerge from the nest. They are 7 cm long and their goal is to reach the water.

The journey between the nest and the sea is full of obstacles, as many predators (birds, crabs, dogs, and other mammals as well as large fish) await.

Wildlife poaching remains a problem for all turtle species found in Madagascar.
