A report published by the Turtle Conservation Coalition calls attention to the grave conservation status of the world's tortoises and freshwater turtles. According to Turtles in Trouble: The World’s 25+ Most Endangered Tortoises and Freshwater Turtles – 2018, more than half of the currently recognized 356 species of turtles and tortoises are threatened with extinction. Among all animals, only the nonhuman primates, with approximately 60% of species threatened with extinction, are in a more precarious state. The report updates earlier assessments, and adds two new species to the most endangered list.
