1 Even today, when air and road travel has made Africa so readily accessible to Europeans and Americans, there are innumerable aspects of African life which tend to take one by surprise. The unfamiliar lies hidden everywhere, and the presence of Western culture seems merely to emphasize this unfamiliarity. Basically, the essence of our reaction to the strange, the unfamiliar, is a sense of fear. Every country contains landscapes that arouse unease—whether it be some remote Alpine valley, the wild lavender fields of Upper Province, or a lonely Norwegian fjord at twilight. But in my own experience West Africa contains more weird and eerie regions—rainforest, mangrove swamp, parched plains of red earth—than any other place that I have seen. It is not only in the foreigner that these land- scapes evoke fear. A large part of all old African religions is devoted to soothing the un- known and the unseen—evil spirits which live in a particular tree or a particular rock, a thousand varieties of ghosts and witches, the ever-present spirits of dead ancestors or rela- tives. I have myself been kept awake at night in Calabar by a friend from Lagos who was convinced that the witches of the east were out to get him, or that he was about to be kid- napped and eaten. During four and a half hours in a canoe along the creeks of the Niger delta, gliding over the still and colorless water beneath an equally still and colorless but burn- ing sky, I, too, have experienced a sense of fear, or at least a sense of awe. Except for the ticking of the little outboard engine the silence was complete. On either hand stretched the silver-white swamps of mangrove, seeming, with their awkward exposed roots, to be standing knee-deep in the water. Where the creek narrowed you could peer deep into these thickets of mangroves--vistas secret, interminable and somehow meaningless. There was no sign of life except for the shrill screech of some unseen bird. I was on my way to the ancient slaving port of Bonny, which we reached in late afternoon. Scrambling up some derelict stone steps (slithery with slime and which had managed to detach themselves from the landing-stage so that you had to jump a two-foot gap to reach wet land), I found myself in an area of black mud and tumbled blocks of stone. The author was kept awake by______.

3 Certainly no creature in the sea is odder than the common sea cucumber. All living creatures, especially human beings, have their peculiarities, but everything about the little sea cucumber seems unusual. What else can be said about a bizarre animal that" among other eccentricities, eats mud, feeds almost continuously day and night but can live with- out eating for long periods, and can be poisonous but is considered supremely edible by gourmets For some fifty million years, despite all its eccentricities, the sea cucumber has sub- sisted on its diet of mud. It is adaptable enough to live attached to rocks by its tube feet, under rocks in shallow water, or on the surface of mud flats. Common in cool water on both Atlantic and Pacific shores, it has the ability to suck up mud or sand and digest whatever nutrients are present. Sea cucumbers come in a variety of colors, ranging from black to reddish-brown to sand-colored and nearly white. One form even has vivid purple tentacles. Usually the crea- tures are cucumber-shaped--hence their name and because they are typically rock inhabitants, this shape, combined with their flexibility, enables them to squeeze into crevices where they are safe from predators and ocean currents. Although they have voracious appetites, eating day and night, sea cucumbers have the capacity to become quiescent and live at a low metabolic rate--feeding sparingly or not at all for long periods, so that the marine organisms that provide their food have a chance to multiply. If it were not for this faculty, they would devour all the food available in a short time and would probably starve themselves out of existence. But the most spectacular thing about the sea cucumber is the way it defends itself. Its major enemies are fish and crabs. When attacked, it squirts all its internal organs into the water. It also casts off attached structures such as tentacles. The sea cucumber will eviscerate and regenerate itself if it is attacked or even touched: it will do the same if the surrounding water temperature is too high or the water becomes too polluted. According to the passage, why is the shape of sea cucumber important
