Leatherback sea turtles are the largest and most unique sea turtles, known for their flexible, leathery skin instead of a hard shell. These turtles can dive deep, hold their breath for up to 85 minutes, and have peculiar diving behavior. Leatherbacks are facing rapid decline due to various threats, leading to the classification of some populations as critically endangered. Respecting their living spaces and avoiding stressful interactions with them is crucial to their conservation.
