Survival of the fittest
Here, there are baby turtles.They are going towards the sea. The females are a darker shade of green and the males are lighter. There are also some crows.
The baby turtles appear delicious to the crows. The crows meals often contain the baby turtles. Since the baby turtles are small and aren't fast enough, the crows can get to them easily.
The male turtles have longer tails and horns near the neck which makes them less edible to the crows, so more of the females are eaten.
The horns of the males and longer tails can determine whether a female turtle is attracted to them or not, which will lead to more reprodcution.
