Baby Sea Turtles Facts

Baby Sea Turtles- It’s an emotional event to see a tiny turtle (known as a “hatchling”) battle it out of the nest and make its way to the sea. Everything from footprints to driftwood and crabs are hurdles, but this slog is essential for continued existence. Raccoons, birds, and fish are just a few of the predators these delicate creatures encounter; some scientists estimate that just one in a thousand will stay alive to maturity in the wild.

An adult female sea turtle proceeds to the water after nesting, departing from her nest as well as the eggs contained in it to grow on their own. The time it takes for an egg to hatch differs between species and is determined by environmental factors like sand temperature. Because the hatchlings lack sex chromosomes, their gender is determined by the temperature of the nest.

Facts about Baby Sea Turtles 

  • Only one in every 1,000 hatchlings will stay alive till maturity, according to estimates.
  • Sea turtle hatchlings consume a wide range of prey, together with sargassum sea weed,  mollusks and crustaceans, jellyfish, hydrozoans, and fish eggs. Unluckily, hatchlings misinterpret rubbish and items such as tar balls for food and consume them.
  • Leatherback as well as flatback hatchlings are much bigger than those of other sea turtle species.
  • Even as hatchlings, leatherback turtles are pelagic (live in open water), and their bigger size aids with temperature regulation.
  • When hatchlings emerge from the nest, they use the natural light horizon, which is typically over the ocean, as well as the white crests of the waves, to arrive at the water. Other light sources, like light from cars, campfires, seashore lighting, street lights, and so on, might lead hatchlings astray, causing disorientation.
  • Hatchlings confront a variety of predators as they leave the nest, including raccoons, dogs, ghost crabs, birds, and fish.
  • A lot of scientists are afraid that increasing global temperatures would cause warmer sand, resulting in more female newborn turtles than male. Find out more about the consequences of global warming on sea turtles.

Baby Turtle Pivotal Temperature 

The temperature of the hatchlings in the nest, referred to as the “pivotal temperature,” determines whether they are male or female. The temperature upon which embryos inside a nest develop into a mix of males and females varies slightly between species, ranging between 83 and 85 degrees Fahrenheit (28-29 degrees Celsius). Females are produced by temperatures above this range, whereas males are produced by temps below this range.

After 45 to 70 days (depending on the species), the hatchlings begin to pip, or break free from their eggs, using a small temporary tooth called a caruncle located on their snout. After emerging from their eggs, they will remain in the nest for several days. During this stage, they will consume their yolk, which is attached to their abdomen by an umbilical cord.

Emergence 

The hatchlings begin to climb out of the nest as a group. They will commonly linger on the surface until the sand temperature cools, which usually implies darkness, when they are less likely to be eaten by predators or overheat. When the baby turtles emerge from the nest, they use clues like the slope of the sand, the white crests of the waves, and the natural light of the ocean horizon to find their way to the water.

If the hatchlings make it down the beach and into the surf, they start a “swimming frenzy” that can last several days and varies in intensity and duration depending on the species. The swimming frenzy keeps the hatchlings away from dangerous nearshore seas where predation is widespread. When hatchlings reach the sea, they begin their “lost years,” during which their whereabouts are unknown for up to a decade. When the young turtles reach the size of a dinner plate, they will return to the coast to forage and grow.
