Recent research has shed light on the elusive 'lost years' of sea turtles, a period where their whereabouts and activities remained a mystery. Scientists have discovered that these turtles are active swimmers in the ocean during this time, which had previously been undocumented. This finding is vital for conservation efforts as it provides insights into the life cycle and habitat requirements of turtles, which are critical for their protection. Additionally, understanding their movement patterns can lead to better management of marine environments and help mitigate threats from human activities.
