There are several types of plants and animals in the Tanami desert. Some native plants include Sturt's Desert Roses, poached egg daisies and honey grevillas. Some animals include mulgaras, bilbies, and rufous hare-wallabies.
Some cacti tend to lean to the south in the desert. The barrel cactus is known to do this.
A few desert plants have a waxy coating that helps protect them from the heat and dry air of the dessert. These plants include some varieties of Yucca trees, Creosote and Beavertail Cactus. The waxy coating blocks the plants pores, trapping the moisture inside to prevent them from drying out.
Desert animals either eat plants or they eat each other. Some eat both plants and animals (omnivores).
