By exploring the different activities that sea turtles engage in, we can gain a deeper appreciation for these incredible creatures, and the importance of their role in the marine ecosystem. In the following sections, we will delve deeper into the world of sea turtles, and explore the fascinating things they do.
What Do Sea Turtles Do?
Sea turtles are fascinating creatures that have been on our planet for over 100 million years. These gentle giants play a crucial role in maintaining the health of our oceans and ecosystems. But have you ever wondered what they do? In this article, we’ll delve into the daily lives of sea turtles and explore their behaviors, habits, and importance in the marine ecosystem.
Habitat and Migration
Sea turtles can be found in all the world’s oceans, from the warm waters of the tropics to the cold seas of the Arctic. They inhabit a variety of habitats, including coral reefs, estuaries, and open ocean. These turtles are known for their incredible migrations, with some species traveling thousands of miles each year to reach their breeding grounds, feeding grounds, or nesting sites.
For example, the leatherback sea turtle migrates over 10,000 miles each year, crossing entire ocean basins to reach its breeding grounds in the Caribbean. This remarkable journey is crucial for the survival of the species, as it allows them to mate, nest, and feed in areas with abundant food and suitable habitats.

Feeding Habits
Sea turtles are omnivores, which means they eat a variety of foods including plants, animals, and carrion. The diet of a sea turtle varies depending on the species, age, and location. Here are some examples of what different species of sea turtles eat:
- Green sea turtles: These turtles are herbivores and feed on seaweed, seagrass, and algae.
- : These turtles are carnivores and feed on crustaceans, mollusks, and fish.
- Leatherback sea turtles: These turtles are specialized feeders and feed on jellyfish, salps, and other soft-bodied organisms.
In addition to their diet, sea turtles also play a crucial role in maintaining the balance of their ecosystems. For example, green sea turtles help to maintain the health of seagrass beds by controlling the growth of algae, which can outcompete seagrass for resources.
Nesting and Reproduction
Sea turtles are known for their remarkable reproductive habits. Female sea turtles come ashore to nest on beaches, where they lay dozens to hundreds of eggs in a nest. The sex of the hatchlings is determined by the temperature of the sand, with warmer temperatures producing females and cooler temperatures producing males.
After incubating for several weeks, the hatchlings emerge from the nest and make their way to the ocean. This journey is fraught with danger, as hatchlings are vulnerable to predators such as birds, crabs, and other animals.
Once in the ocean, the hatchlings begin their journey to adulthood, which can take several decades. Sea turtles reach sexual maturity at different ages, depending on the species, with some species taking up to 50 years to reach maturity.
Social Behavior
Sea turtles are generally solitary animals, but they do exhibit some social behavior. For example, female sea turtles often nest in large groups, with hundreds of females nesting on the same beach. This social behavior helps to increase the chances of successful nesting and reduces the risk of predation.
In addition, sea turtles have been observed exhibiting complex behaviors such as communication, cooperation, and even play. For example, loggerhead sea turtles have been observed playing with seaweed and other objects, while green sea turtles have been observed communicating with each other using a variety of vocalizations.
Conservation Status
Unfortunately, sea turtles are facing numerous threats to their survival, including habitat destruction, pollution, overfishing, and climate change. Six out of seven species of sea turtles are listed as vulnerable, endangered, or critically endangered on the IUCN Red List.
The main threats to sea turtles include:
- Habitat destruction: The destruction of coral reefs, mangroves, and seagrass beds reduces the available habitat for sea turtles.
- Pollution: Plastic pollution, oil spills, and other forms of pollution can harm sea turtles and their habitats.
- Overfishing: Sea turtles are often caught accidentally in fishing gear, which can lead to injury or death.
- Climate change: Rising temperatures are altering the sex ratios of hatchlings, making it more difficult for populations to sustain themselves.
Importance in the Marine Ecosystem
Sea turtles play a vital role in maintaining the health of marine ecosystems. They help to:
- Maintain seagrass beds: Sea turtles help to control the growth of algae, which can outcompete seagrass for resources.
- Regulate jellyfish populations: Leatherback sea turtles feed on jellyfish, which helps to regulate their populations and prevent them from overgrazing.
- Disperse seeds: Sea turtles help to disperse seeds from one location to another, which helps to maintain the diversity of marine plant species.
