This species is considered vulnerable in the Mediterranean, in part because its breeding process is infrequent and precarious. So it doesn't help when people build bars adjacent to nesting areas.
This sea turtle spends most of its life in saltwater and estuarine habitats, with females briefly coming ashore to lay eggs.
Loggerhead turtles are amazing creatures - but the are also vulnerable, in part because they only lay eggs once every two to three years.
After they lay their eggs, the female turtles return to the water.
While they are incubating, the eggs are vulnerable to predators and human incursion.
If the egg survives the incubation period, a baby loggerhead is born.
The baby turtle must then make a treacherous journey to the sea, surviving predators along the way. Loud noises from human activity can cause them to get lost.
A large number of hatchlings die during the journey to the sea. Those that reach the water can grow to be adults - if they don't starve in their first days.
Also as adults, loggerheads face numerous threats in the sea. This loggerhead has been fitted with a prosthetic titanium beak after being mutilated in a boating collision.
Senegalese coastal villages are affected by climate change and overfishing. While many men leave to seek employment abroad, women often stay behind and try to adapt to life between rising sea levels and desertification.
Closely related to the spider and around since long before the dinosaurs, the horseshoe crab has light blue blood that's vital for medical research. But can these living fossils survive the age of man?
Researchers are honing in on a little-studied but significant consequence of climate change: male infertility. Could this potential cause of extinction and biodiversity loss also threaten the human species?
The decomposing bodies of some 300 sea turtles were found off El Salvador's coast, raising questions about how they could die so quickly. Now scientists have found out why. The culprit? A tropical storm and microalgae.
