The most common type of structural trap is formed by an anticline, a structure with a concave (as viewed from below) roof caused by the local deformation of the reservoir rock and the impermeable cap rock. In this case, the intersection of the oil-water contact with the cap rock determines the edges of the reservoir.
Wild Gerbils. Gerbils are small rodents but they are not rats! They normally have white bellies and are agouti coloured. They live in the wild in Central Asia, India, the Middle East, and Africa. They roam the savanna, steppe, hot desert and semi-desert areas of these nations.
Alaska Fish and Game wildlife biologist Jeff Selinger said snakes in Southcentral Alaska are not as far-fetched as one would think. The common garter snake is the only species of snake found in Alaska and can be found as far up as Northern Canada, he said. Selinger said no snakes have been recorded living in the wild in the Kenai Peninsula, but that does not mean people cannot have them as an indoor pet. Some pet stores sell garter snakes, he said. Another possibility that the snake arrived in Alaska via cargo ship, he said. â(Garter snakes) live off insects and frogs,â he said.
