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.
Gerbils. Gerbils are generally diurnal animals (active during the day), constructing deep, dark, underground burrows. Gerbils may live for up to 3-4 years, although some may live longer. Take a look at our pet search page to find gerbils up for rehoming. Your duty of care. Gerbils are often kept by young children, because they have a great deal of character. However, their needs are actually very complex and owning one is a big responsibility. If you own or are responsible for gerbils, even on a temporary basis, you are required under the Animal Welfare Act to care for them properly.
