ALL ABOUT Sea Turtles Turtles vs. Tortoises The main difference between these related reptiles is where they live! Tortoises live entirely on land, while turtles usually live in or near the water. Tortoises have dome-shaped shells and sturdy legs that can support their weight on land, while turtles have paddle- shaped limbs, webbed feet, and slimmer shells that allow them to move easily in the water. VS. Hawksbill Types of Sea Turtles There are seven different species of sea turtles: Green Turtles, Leatherbacks, Loggerheads, Hawksbills, Flatbacks Olive Ridleys, and Kemp’s Ridleys. Olive Ridleys and Kemp’s Ridleys are the smallest species, measuring about 2 ft. long and weighing up to 100 lbs. Leatherbacks are the largest species, measuring 4-6 ft. Loggerhead long and weighing up to 1,100 lbs. Where do sea turtles live? Sea turtles spend their entire lives at sea! They live in almost every ocean habitat in the world, except the coldest waters around the north and south poles. Leatherbacks can live in the coldest temperatures and are sometimes found in water as cold as 40 degrees Fahrenheit. However, most turtles prefer water closer to 70 degrees. What do sea turtles eat? Different species of turtles eat different foods, including jellyfish, seaweed, algae, coral, crabs, and sponges. Some sea turtles have a beak-like mouth with sharp edges that is perfect for biting chunks of seaweed or scraping off algae. Other turtles have strong jaws that allow them to crush hard-shelled prey. ALL ABOUT Sea Turtles Where do sea turtles lay their eggs? Many female turtles travel thousands of miles to lay their eggs on warm, tropical beaches. The female moves slowly up the beach and begins to dig a nest. After laying the eggs, she covers them with sand and returns to the ocean. The average sea turtle nest is about 30 inches deep and contains between 50-130 eggs, depending on the species. How do baby sea turtles survive on their own? About six to seven weeks later, the eggs are ready to hatch! Baby sea turtles use a special “egg tooth” to help them crack through the egg. It takes several days for the turtles to crawl out of the nest, and they usually wait until evening, when the sand is cooler, to fully emerge. They use the natural horizon light and reflection off the waves to guide them toward the water. Do sea turtles have predators? Turtle eggs are often eaten by birds, raccoons, and dogs, and more than 90% of hatchlings are snatched by seabirds, crabs, large fish, and other predators. Adult turtles have few natural predators, but they are sometimes eaten by sharks. Unfortunately, the biggest threat to sea turtles comes from humans. Why are sea turtles endangered? Human behavior has threatened sea turtle populations around the world. Many turtles are hunted for their meat, eggs, and shells (which people use for jewelry) or get tangled in huge fishing nets. Plastic bags are especially dangerous to turtles because they confuse them with jellyfish and eat the plastic by mistake! Additionally, turtle feeding grounds and nesting sites are impacted by climate change. ALL ABOUT Sea Turtles Help the Hatchlings In addition to natural predators, sea turtle hatchlings face a human-made threat. Light from cars, streetlights, and buildings distracts turtles from the natural moonlight that guides them to the water. As a result, many baby turtles scurry towards these lights, instead of toward the ocean. You can help by turning off lights along the beach during hatching season and using red or amber bulbs (which are less distracting) when necessary. Friendlier Fishing In most countries, it is illegal to fish or hunt turtles, but it still happens accidently. Many turtles are mistakenly caught as “bycatch” in fishing nets and traps. Some become so entangled that they die before they can be cut loose and released. You can help by researching and purchasing fish from responsible fishing industries. The Plastic Problem Most plastic in the oceans was not dumped there. Instead, it is swept from cities and towns into rivers, which carry it downstream into the ocean. Here are 3 ways you can help: 1. Choose plastic-free options 2. Collect plastic and garbage from beaches, parks, etc. 3. Recycle plastics when possible Turtleshell Trade Hawksbill turtles are hunted to make jewelry and other souvenirs for tourists. As a result, Hawksbill turtles became critically endangered, and it is now illegal to sell or trade items made from their shells. However, illegal trade is still happening worldwide. You can help by avoiding turtle shell (sometimes called “tortoiseshell”) products.
