![]() In the Sahara Desert, sandfish live beneath the dunes. Animals cannot take shelter in the unstable sand of a dune and must search for fresh water. Some grasses with shallow root systems, such as beachgrass, are common to sand dune ecosystems. Often, sand dunes are located next to oceans, so plants must be tolerant of a very salty atmosphere. There is little soil in a sand dune, so plants usually cannot take root. Life In Sand Dunes Few species can live in the shifting world of sand dunes. Parabolic dunes are also called blowouts, because winds blow out the center of the dune, leaving just a rim on the outside. Their shapes are roughly the same, but the slipface of a parabolic dune is on its inward side. Parabolic dunes are similar to crescentic dunes. ![]() The wind can blow material onto the dune from any side. They are circular and do not have a slipface. The sand dunes of the Sahara Desert ergs are star dunes. Star dunes develop where winds come from many different directions. Star dunes have pointed ridges and slipfaces on at least three sides. Linear dunes develop where wind pressures are nearly equal on both sides of a dune. Some linear dunes are shaped like a wiggling snake, with regular curves. Linear dunes form straight or nearly straight lines. Crescentic dunes are the fastest-moving type of dune, and also the most common. The wide side of a crescentic dune is its windward side, with a small, semi-circular slipface on the other side. Crescentic dunes are shaped like crescents, or the shape of a wide letter C. There are five major dune shapes: crescentic, linear, star, dome, and parabolic. Shapes of Dunes Dunes can be very large geographic features or just small bumps. Underwater dunes, called subaqueous dunes, are common in the ocean, rivers, and canals. Dunes can also be formed by strong currents beneath the water. The Skeleton Coast Erg in Namibia extends 2-5 kilometers (1-3 miles) in length and across a width of 20 kilometers (12.7 miles). A collection of dunes is called a dune belt or dune field. A slipface is usually smoother than a dune's windward side. A dunes slip face is simply the side without wind. A dune's windward side is the side where the wind is blowing and pushing material up. Every dune has a windward side and a slipface. Dunes form when wind blows sand into a sheltered area behind an obstacle. One of our best tips for decorating with nature posters is to combine them with real plants to create a wonderful, jungle-like feel.A dune is a mound of sand formed by the wind, usually along the beach or in a desert.
