Marine life same environmental problems and feeding niches have resulted in similar adaptations. Examples include albatross, penguins, gannets, and auks. In general, marine birds live longer, breed later and have fewer young than terrestrial birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Marine birds can
Cape Byron Marine Park (EAC), which transports warm water currents into temperate zones. The presence of the EAC plays an important role in transporting tropical flora and fauna into southern hemisphere temperate zones. The Cape Byron Marine Park is located on the Eastern Overlap Zone where warm waters form the north converge with cooler waters from the south. The local marine habitats include exposed and sheltered sandy beaches, rocky shores, rocky reefs, submerged pinnacles, small rocky islands, coral communities, riverine estuaries, coastal creeks and lakes, and sandy seabed habitats. The Major ecosystems in the Cape Byron Marine Park are Estuaries, Rocky Shores and Platforms,
