Plant and animal life
Much of the continental portion of Equatorial Guinea is covered by dense tropical rainforest that has long been exploited by the lumbering industry. More than 140 species of wood are found, of which the most important commercially are okume (Aucoumea klaineana), African walnut, and various mahoganies. A secondary forest growth has replaced the virgin rainforest. Mangroves fringe long stretches of the coast as well as riverbanks. Bioko has a greater variety of tropical vegetation, including mangroves.
The continental region has a rich animal life that includes gorillas, chimpanzees, various monkeys, leopards, buffalo, antelope, elephants, hippopotamuses, crocodiles, and various snakes, including pythons. Insects abound, including the tsetse fly and the malaria-bearing Anopheles mosquito, as well as hosts of ants, beetles, spiders, and termites. Bioko has no big game but has various monkeys, dwarf antelopes, and rodents, as well as mosquitoes and other insects.
