The Caribbean presents a fascinating paradox in the sea turtle conservation story. On one hand, Costa Rica hosts the world’s longest running and most iconic sea turtle conservation initiative. Meanwhile, just up the coast in the neighbouring Nicaragua, one of the world’s few legal sea turtle fisheries flourish. So how does this contradiction play out for sea turtles of the … Read More

Ever wondered why we know so little about male sea turtles? Or why most of our knowledge primarily comes from the female half of the species? Male sea turtles are notoriously elusive, and unlike their female counterparts, male turtles rarely venture onto beaches. This makes studying them in the wild a real challenge. So how much do we know about … Read More

Each year, hundreds of thousands of sea turtles are accidentally caught in fishing nets—a phenomenon known as bycatch, which poses a grave threat to these already vulnerable species. “Even the death of one individual has implications for a population that’s already threatened. But in the case of fisheries, it’s also not good for the reputation of the fisheries” says Dr … Read More

After a sea turtle hatchling scurries down the beach and plunges into the waves, it vanishes into the ocean, remaining incognito for the next few years. This early period of a sea turtle’s life history, often referred to as the ‘lost years’, has long intrigued scientists, leaving many questions about this mysterious stage. Where do these hatchlings go? And when … Read More

Sea turtle hatcheries are a popular conservation strategy across the world, easily recognised as fenced enclosures on sea turtle nesting beaches. These enclosures house turtle eggs, relocated from natural nests on the beach, to a more controlled environment that protects them from various threats. Ideally, a hatchery would produce more hatchlings than a natural nest. However, relocating sea turtle eggs … Read More

Looking at an egg and wondering when and if it ever hosted life is a curiosity most of us are familiar with. But what about sea turtle eggs? With each sea turtle nest containing anywhere between 60-120 eggs, not all of them hatch into baby sea turtles – some instead exhibit hatching failure. But why do these eggs remain unhatched, … Read More

Did you know that sea turtles take about 20-30 years to reach sexual maturity and reproduce? “The turtles that you’re looking at on the beach this year may have hatched out of their eggs 35 years ago. So what happened 35 years ago is going to determine what kind of population you have now. And what you do now is … Read More

The earliest ancestor of modern day sea turtles appeared about 120 million years ago. Interestingly, these species laid hard-shelled eggs, as opposed to the soft-shelled eggs that we see now. Then a big mass extinction event around 66 million years ago wiped out about 50 percent of plants and animals. But not these guys – sea turtles managed to survive! … Read More
