This episode covers the habitats which are so remote and cut off from the rest of the world that they develop very specific sets of flora and fauna. These include a remote island 250 miles off the coast of Africa in the Indian Ocean, coral atolls, islands in Indonesia, Hawaii, Easter Island and New Zealand. Covers such diverse life forms as coral, crabs, tortoises, giant floating seeds, flightless birds, the dodo, Komodo Dragons, birds and insects which live in volcanic wastelands, tuataras, kiwi, moas, kea and the effects on them of feral cats. Includes discussion of how these animals arrived in these remote locations initially and how they have adapted to suit their habitat.
