As a group, sea turtles represent a primitive and unique component of biological diversity, and an important part of marine ecosystems.

Sea Turtles belong to the oldest living lineage of reptiles and even though they have endured drastic environmental changes without requiring large adaptive changes, these animals are finding it difficult to survive nowadays. In the last two hundred years, a particular combination of factors such as commercial over-fishing, bycatch, habitat destruction of feeding, nesting and resting grounds, and more recently, marine pollution and climate change, have led to the decline of sea turtle populations, often to critical levels, and many populations have already become extinct.
