Life cycle of marine turtle

• The entire life cycle of marine turtle still remains a mystery. Once their hatchlings enter the sea, upon maturity, only female turtles visit the coastline for breeding, and that too for a couple of hours only.
• Turtles leave identifying marks in the sand, when they arrive to the shore and return to the sea. Tracks 2 to 2.5 feet wide appear on the sand when the turtle crawls.

•  Male turtles never visit the seashore. Turtle’s long life span and ability to migrate a few hundred thousand kilometres makes it difficult for researchers to study marine turtles.
