Did you know? There is only one species of leather-shelled Sea Turtle, the Leatherback.

Welcome to the world of Sea Turtles! There are seven different species of Sea Turtles (scientific name Chelonioidea) around the world, each with their own unique characteristics and habits. The flatback, green, hawksbill, leatherback, loggerhead, Kemp’s ridley, and olive ridley Sea Turtles are all ectothermic cold-blooded reptiles that have evolved over millions of years to survive in the ocean. Depending on the species, Sea Turtles can weigh between 70 to 2000 pounds with the smallest Turtles being only about 2 ft long, and the largest being up to 6 feet! Sea turtles are separated into two categories: hard-shelled and leather-shelled. Their shells are an important part of their bodies that help protect themselves from predators and environmental threats. Although Sea Turtles have been around for thousands of years, their populations are currently struggling and need our help!

The rarest sea turtle, the Kemp Ridley, live primarily only in the gulf of Mexico, and occasionally on the east coast of the US.

Sea turtles are found in almost all of the world’s oceans, except for the polar regions. These fascinating creatures prefer warm, tropical waters with temperatures above 70 degrees Fahrenheit. They can be found in the waters surrounding North America, South America, Africa, Europe, Asia, and Australia. Sea turtles are also known to migrate thousands of miles from their nesting beaches to feeding areas and back again. Some of the most popular places to see sea turtles include the beaches of Costa Rica, the Caribbean islands, the Great Barrier Reef in Australia, and the Hawaiian Islands.

What are Sea Turtles?

Sea turtles are aquatic reptiles that have been around for millions of years. They have a unique anatomy that allows them to survive in the ocean. Their beaks are specially designed to help them eat their favorite foods, such as jellyfish, crabs, and seagrass. They don’t have teeth, but instead, their beaks are sharp and serrated, which helps them tear their food into smaller pieces.
They use their front flippers to propel themselves through the water and steer, while their back flippers help them swim faster. Sea turtles also have a streamlined body and a large, sturdy shell that protects them from predators and environmental threats.
One of the most striking features of sea turtles is their large eyes, which help them see in low-light conditions and navigate their way through the ocean. They also have a keen sense of smell.
It is commonly mistaken that turtles can be removed from their shells. Se Turtles are very much attached to their shells, and their spines actually run along the top of the inside of the shell.

Did you know? A turtle shell is extremely hard, and can withstand thousands of pounds worth of pressure.


Sea turtles are known to be solitary creatures, and they generally prefer to spend their time alone. They are not aggressive and tend to be calm and peaceful animals. However, during the breeding season, male sea turtles can become more territorial and may compete for the attention of a female.
In addition to their physical adaptations, sea turtles also have some unique behaviors. They are known to migrate long distances between their feeding and nesting grounds, and females return to the same beach where they were born to lay their eggs. They also have a special ability to navigate using the Earth’s magnetic field, which helps them find their way across vast stretches of ocean.
Despite their solitary nature, sea turtles are vulnerable to human disturbance and can become stressed when they are exposed to too much activity or noise. It’s important to respect their space and avoid disturbing them while they are resting or nesting.

Did you know? Researchers still know very little about the lives of young sea turtles, they are so small and illusive in the ocean’s open waters.

Did you know? Sea Turtles can eat, on average, about 261 jellyfish per day.

The digestive system of a sea turtle is specially adapted for their diet of jellyfish, crabs, and seagrass. Their sharp and serrated beaks help them tear their food into smaller pieces, which are then swallowed whole. Sea turtles have a digestive system that also allows them to break down tough plant fibers, such as those found in seagrass.
Human pollution is a major threat to sea turtles, as they often mistake plastic bags and other debris for their favorite food, jellyfish. When sea turtles ingest plastic, it can cause blockages in their digestive system.


Most sea turtles breed in warm waters near the equator, such as the beaches of Florida, Costa Rica, and Australia. The gestation period for sea turtles varies by species, but it usually lasts between 6 to 10 weeks.
Sea turtles usually lay their eggs at night, on sandy beaches above the high tide line, where they dig a hole with their flippers and deposit their eggs. Some species return to the same nesting beach where they were born. Once the eggs are laid, the female turtle covers them with sand and returns to the sea. The incubation period for sea turtle eggs is typically around 60 days, and the hatchlings use a specialized tooth called a “caruncle” to break out of their eggshells before emerging from the sand and heading to the ocean. They emerge from the sand all together and head towards the ocean, following the brightest horizon, which is usually the reflected light of the moon over the water. This instinct is known as “imprinting,” and it guides them towards the ocean. Hatchlings face several threats during this journey, including predators such as birds, crabs, and raccoons that prey on the hatchlings as they make their way to the ocean. Hatchlings can also be disoriented by artificial lights from buildings, which can lead them away from the ocean and towards danger like streets, sidewalks, or parking lots.

Did you know? Female Sea Turtles lay between two and six clutches of eggs, each containing 65 to 180 eggs.


Sea turtles face a range of threats in the wild, from natural to human-made, which put their survival at risk. One of the most significant threats is habitat loss, caused by coastal development, climate change, and erosion, which can destroy their nesting sites and food sources. Another significant threat is boat strikes, which can injure or kill sea turtles, especially in areas with high boat traffic. Light pollution is also a danger, as artificial lights from buildings and coastal developments can disorient hatchlings and lead them away from the ocean and can also interfere with nesting behavior. Marine debris, including plastic waste and fishing gear, can entangle or suffocate sea turtles and destroy their habitats. Climate change is also a significant threat, as rising sea levels and temperatures can impact the turtles’ nesting habitats and food sources. Overfishing can reduce the turtles’ food sources, and the accidental capture of Sea Turtles in fishing gear is a significant problem. Lastly, poaching and the illegal trade of sea turtle products, including their meat, shells, and eggs, are also a severe threat to their survival. It’s essential to take measures to address these threats to ensure the continued survival of Sea Turtles, such regulations to reduce boat traffic in critical habitats, reducing light pollution, beach cleanup efforts, and creating protected marine areas.


The population status of sea turtles is a cause for concern, as all seven species are either endangered or critically endangered. According to the International Union for Conservation of Nature (IUCN), the global population of sea turtles has declined by over 80% in the last century. This decline is due to a range of factors, including habitat loss, overfishing, pollution, and climate change, which have all had a significant impact on sea turtle populations. The loss of sea turtles has had significant ecological and economic consequences, as they play a crucial role in maintaining healthy marine ecosystems.

How to Help

Here are some things you can do to help save the Sea Turtles! Reduce your pollution. Help pick up any trash that you see! This is an easy way to keep dangerous objects away from Sea Turtles so they do not accidentally ingest it. Participate in Beach Clean-ups! These are so important in helping make the beach a safe and desirable place for Sea Turtles and their nests. Also avoid pesticides and fertilizers in your yard. Pesticides and fertilizers drain into lakes and rivers in run off, causing deadly algae blooms, and destroying precious Sea Turtle sea grass beds and other food sources. Practice safe boating. Unsafe boating causes deadly Sea Turtle boat strikes. It is important to follow all boating rules and regulations and follow all posted signs. Wearing polarized sunglasses can help you spot Sea Turtles from boats. Give space and do not feed them! Sea Turtles, just like any other animals, need space and deserve respect. It is important to give the Sea Turtles plenty of space when we are swimming or boating in their habitats. Petting Sea Turtles is not respectful and can make them feel unsafe. Turn off all artificial lights at night while at the beach. Artificial lights disorient newly hatched sea turtles. By working together, we can save all Sea Turtle populations!
