the earth is tilted and the sun goes down earlier some parts of the year
i would say that animals such as sea turtles and clown fish protect there offspring by putting them in areas that are much harder for predators to access. clown fish for example lay their eggs in the tentacles around a sea anemone to prevent predators from eating them because they are poisonous to all dish but clown fish. and sea turtles burry there eggs on land so that the predators cannot eat their eggs. hope this .
