was watching a documentary and saw theses baby turtles that almost straight running towards the sea once hatched, and couldn’t understand that how they knew about that sea is where they should be going, without any adult turtle nearby or something that could guide them…
In: Biology
This was on here I think 2 years ago actually, but essentially it’s a predetermined genetic instinct. They are just instinctually attracted to the largest and brightest open area. They hatch at night so that usually ends up being the sea they go to, because the ocean surface reflects the moon and ends up being the brightest surface they notice. As they’re usually hatching on or near the beach .
