Sea Turtle Migration: What Kind of Cue they Use for Navigation?

Sea turtle is a long-lived marine reptile. The long evolution history of this animal results in great interests to understand its population traits. However, the endangered status of sea turtle prevents us from conducting extensive studies. In spite of great efforts have devoted to the researches on the biology of sea turtle, little progress was achieved for decades. Only in recent years, the advancement of technologies allows us to solve these miseries gradually. Current major topics involves in population genetic, biologging (e.g. satellite telemetries, diving behavior), nesting ecology (include nesting environment and embryogenesis), diet, pollution, plasma biochemistries, parasites, fisheries interactions and global climate changes. Still, with the limit sample size, the understanding of the sea turtle biology is mostly in infant stage. Controversies, however, occurred in the interaction between sea turtle behavior and other disciplines. The most obvious one is the importance of migratory cues for sea turtles.
