Flightless bird more species of flightless birds (including the kiwi, several species of penguins, the takahe, the weka, the moa, and several other extinct species) than any other such location. One reason is that until the arrival of humans roughly a thousand years ago, there were no large land predators in New Zealand; the main predators of flightless birds were larger birds. Ratites belong to the superorder Palaeognathae birds, which include the volant tinamou, and are believed to have evolved flightlessness independently multiple times within their own group. Some birds evolved flightlessness in response to the absence of predators, for example on
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,
