No. Nocturnal activity is for most animals a way to avoid predators. Penguins don't have predators on land, so they rest at night.
The first animals to enter land were the invertebrates, followed by some fish which later evolved into amphibians.
Sea mammals and sea birds visit Antarctica's beaches in order to breed on land, where there are no predators.
Nutrients from land will wash into the water. Land-based predators may eat aquatic animals and vice-versa.

Land animals that eat water animals typically include predators like bears, raccoons, otters, and some types of birds such as herons and kingfishers. These animals hunt for fish, amphibians, and crustaceans near bodies of water as part of their diet.
No land animals exist on Antarctica: it's too cold and there is no food chain. Sea mammals and sea birds do visit Antarctica's beaches to breed, because there are no land predators there.
