Sea Turtle Information For Kids

1. What Are Sea Turtles?

Facts about Sea turtle for kids

Sea turtles, also known as marine turtles, have been on planet Earth since the late Jurassic era. All sea turtles species, except the leatherback, belong to the Cheloniidae family. The leatherback belongs to the DermochelyidaeiA family of turtles having the largest living sea turtles family and is its only type that is still in existence. Unlike other turtles, the sea turtle cannot draw up its legs and head into its protective shell or the carapace.

2. How To Identify A Sea Turtle?

The sea turtle’s major difference from other turtles is its shell. Sea turtles have big shells that are made of bone and cartilage. Their color varies from species to species. Shells of all sea turtles, except the leatherback, have a layer of thin plates called scutes covering it. Scutes are flexible but firm. The species of sea turtles is mainly identified by the number and pattern of scutes. However, the leatherback’s shell has a leathery skin instead of scutes covering its shell. It acts as an insulator and enables the leatherback to easily survive in cold waters. The lower side of the turtle, the ventral, of the shell is known as the plastron.

3. How To Determine The Sex Of A Sea Turtle?

When younger, sea turtles appear the same externally irrespective of their gender. As the turtles grow older, the males show longer and thicker tails as compared to their female counterparts. The tail of the males tends to extend further than the hind flippers. This is because the male’s reproductive organ is situated at the base of its tail.

4. Where Do Sea Turtles Live?

Sea turtles live in warm and temperate seas around the globe. They spend more time in the water than land. They come on land mostly to lay eggs. Adult sea turtles are generally spotted in coastal waters, bays, lagoonsiShallow water bodies separated from the larger ones by landforms such as islands or coral reefs , estuariesiPartially enclosed water bodies where rivers meet the sea and even the open sea whereas the younger turtles live around bays, estuaries, and the sea.

5. What Is The Lifespan Of Sea Turtles?

Since sea turtles live in deep waters it is difficult to ascertain much about them. However, scientists believe that sea turtles outlive humans and can live more than 150 years.

The food habits of sea turtles depend on the species of sea turtles. Some species are carnivores, eating other animals, while some sea turtles are herbivores eating only plants. Some turtles are omnivores i.e. they consume both plants and meat.

7. How do sea turtles breathe?

Sea turtles, being air-breathing reptiles with lungs, regularly come to the surface for breathing. During this process, a sea turtle efficiently refills its lungs through a swift, explosive exhalation followed by rapid inhalation. The large size of their lungs facilitates swift oxygen exchange, avoiding the trapping of gases during deep dives.

8. How long can sea turtles stay underwater?

While active, sea turtles need to swim to the ocean surface every few minutes for breathing (1). Although unable to breathe underwater, they showcase the remarkable ability to hold their breath for long periods—ranging between four to seven hours during rest. In this breath-holding state, their heart rate significantly slows down to conserve oxygen, with up to nine minutes passing between heartbeats. This adaptation allows sea turtles to stay submerged for prolonged durations (2).

9. What Are The Different Species Of Sea Turtles?

Green sea turtle, Leatherback sea turtle, Loggerhead sea turtle, Hawksbill sea turtle, Kemp’s Ridley sea turtle, Olive Ridley sea turtle, and the Flatback sea turtle are the types of sea turtles still in existence.

10. Facts And Information About Green Sea Turtle

  • Description: Chelonia mydas is named as Green Sea Turtle because the fat under its shell is green in color. The green turtle is about 5 ½ feet long and weighs up to 700 pounds. It has a single pair of scales before its eyes and has a small head. The top of its shell is red and orange. Scientists believe that the color on its shell changes through its lifetime.
  • Diet: The newborn generally eats other sea animals like worms and insects. As they grow older, around the age of 3 years, they turn vegetarians and stop consuming meat thereafter. They mostly eat algae and seagrass
  • Reproduction: Green sea turtles mate every two to four years. Male turtles return to their birth location for mating. On the other hand, female turtles have multiple breeding grounds and may not always mate in the same place. These turtles mate in shallow waters close to the shore. Female turtles lay up to 100 to 200 eggs.
  • Habitat: Green sea turtles are mostly found in temperate and tropical waters. They only venture around coastlines and islands. They prefer regions having plenty of seagrass beds (3).

The largest nesting population of Green Sea Turtles is found in Costa Rica and Australia (12).

11. Facts And Information About Leatherback Sea Turtle

  • Description: Dermochelys coriacea commonly known as the Leatherback Sea Turtle is the largest sea turtle and is the world’s fourth largest reptile. It is the only sea turtle that does not have a hard shell. It is around 7 feet long and weighs more than 2,000 pounds. The ridges along their carapaceiThe protective shell on the back of some animals and the streamlined body shape enable it to smoothly move in water and easily cover large distances. Its carapace is dark gray or black in color with white or pale spots.
  • Diet: Leatherback is carnivores but its jaw is not strong enough to chew on hard-bodied prey. They mostly survive on soft-bodied animals like jellyfish and salps.
  • Reproduction: Leatherback sea turtles mate in water between the age of 8 and 15 years. They mate according to seasons. The female leatherback sea turtle lays up to 80 fertilized eggs and 30 unfertilized eggs in each nest. Female leatherback turtles may not necessarily create a nest in the same beach.
  • Habitat: They live in the open ocean and are found in the Atlantic, Pacific, Indian Oceans, and the Mediterranean Sea. They are the only species that can easily survive under water below 40 degrees Fahrenheit (4).

12. Facts And Information About Loggerhead Sea Turtle

The females can reproduce multiple times in one mating season. The female turtle lays around 100 to 126 eggs in each nest that takes about 2 months to hatch. Therefore, it is said that migration plays a major role in reproducing turles.
  • Habitat: They prefer living along beaches with grainy sand. However, they are also found along the continental shelves of the major oceans Atlantic, Pacific, and Indian (5).

13. Facts And Information About Hawksbill Sea Turtle:

  • Description: Hawksbill sea turtle has a small narrow head and hawk-like beak, hence the name. It is scientifically known asEretmochelys imbricata.

  • Reproduction: They mate every two to three years and prefer mating in shallow waters close to beaches. The females lay about 100 to 150 eggs in a nest that takes around 60 days to hatch.
  • Habitat: Hawksbill Sea Turtles are mostly found in the Atlantic, Indian, and Pacific oceans. They avoid venturing into deep waters and mainly move around rocky areas. Their place for settlement is areas having plenty of sponges with nesting sites at a close distance. Coral reef areas are mostly populated with Hawksbill sea turtles (6).

14. Facts And Information About Kemp’s Ridley Sea Turtle:

  • Description: Kemp’s Ridley Turtle derives its name from a fisherman named Richard Kemp, who discovered this turtle. Its scientific name is Lepidochelys kempii. They are one of the smallest sea turtles weighing barely 100 pounds with a length of around 2 feet. They are the most endangered species of sea turtles. Their carapace is wide and round and is generally olive-gray in color. Its plastron is white to yellowish.

The female turtles opt for sandy beaches in tropical and subtropical areas for nesting the eggs. The flatback has very limited distribution and can nest and breed only in Australia.
  • Habitat: Flatbacks do not travel over a large area like other turtles and are only found in Indonesia, Australia, and New Guinea. They prefer grassy shorelines with coastal reef areas being their most ideal habitat.

17. Why Are Sea Turtles Vital To The Ecosystem?

  • Seagrass is a breeding and feeding ground for several marine animals. Maintaining seagrass is important because they are a means to sustain life under water. Sea turtles maintain the seabed by eating seagrass They stop sea grass from overgrowing or getting longer blades.
  • Dune vegetation is essential to maintain sand around beaches. The egg shells of sea turtles have nutrients that boost dune vegetation which majorly improves the quality of sand. Dune vegetation helps to hold the sand and protects the beach from erosion.
  • Leatherback mainly eats jellyfish that thrive on fish larvae. The decline in leatherback population has led to an increase in jellyfish which is a major reason for the decline in fish.
  • Sea turtles help to maintain the balance in the marine and sand system. If these reptiles go extinct these two ecosystemsiA system where the living organisms and their physical environments interact with each other will be heavily affected directly impacting human life. That is why sea turtle conservation is important.

18. Why Are They Endangered?

Sea turtles may be the longest surviving creature on planet Earth but recently its survival has been threatened to the extent that it has been listed as an endangered species. The causes for the decline in their population are as follows:

  • Fishing Gear: Hundreds of sea turtles accidentally get caught in fishing nets and longlines yearly. They are either killed or injured in these fishing operations. The National Oceanic and Atmospheric Administration’s Fisheries Service (NMFS) has taken several serious measures to protect threatened sea turtles in the Gulf of Mexico.
  • Artificial Lights: Female sea turtles prefer quiet and dark beaches to nest their eggs. However, the increasing human population around coastlines has led to a rise in artificial lightning’s which discourage females from entering well-lit areas of the beach. They instead opt for isolated regions of the beach which are not ideal for nesting of eggs. Moreover, brightly lit areas confuse hatchlings and they are unable to reach the water which can get them hunted down by predators.
  • Natural Predators: The eggs laid by female sea turtles face a threat from predators such as crabs, raccoons, and boars. It is important that these eggs are protected from such predators. Hatchlings further have to dodge threats of birds, coyotes, and sharks to survive. Furthermore, female turtles have been attacked by dogs when they come on land to lay eggs. However, the increasing human population around coastlines has led to a rise in artificial lightning which discourages females from entering well-lit beach areas. they are unable to move swiftly and defend themselves on land.
  • Water Pollution: Large-scale pollution and incidents of oil spills in water bodies have had a negative impact on the natural habitat of sea turtles. Contamination of seas and oceans not only kills aquatic animals but also poison the plants that grow underwater.
  • Global Warming: The increasing temperatures across the globe have not spared sea turtles. The rise in sea level affects turtles too. Sea turtles have a sharp memory. Once they lay their eggs in a particular spot on a beach they return to the same place years later to hatch their eggs. Loss of coastline leaves no place for sea turtles to create a nest for their eggs. Also, the temperature of the sand plays an important part in influencing the gender of the turtle. Generally, the eggs laid in the lower, cooler, part of the nest turn males on hatching, hatchling from the upper, warmer, part of the nest become females. If the temperature continues to rise, the male population will decline, leading to a catastrophic imbalance in genetic diversity.

19. What Can You Do To Protect And Preserve Sea Turtles?

  • Maintain cleanliness at beaches and do not litter.
  • If you happen to spot a turtle at a beach, do not go too close to it. You might scare it.
  • Contribute and participate in restoration events that restore sea turtle nesting beaches.
  • Avoid having campfires at beaches as sea turtles are easily attracted to fire and they die in these fires.
  • Spread awareness amongst your family and friends about the dwindling numbers of sea turtles. Help garner signatures for petitions that ask the government to take action for the preservation of sea turtles.
  • Do not leave chairs, umbrellas, and boats at the beach at night. These things confuse turtles and deviate their tracks from the place of nesting. They also obstruct hatchlings from entering the sea.
  • When buying fish, ensure that the fish has been caught by responsible fisheries who use turtle-friendly methods to capture fish.
