smooth. It has a long, sticky tongue to help it catch insects.

their habitat.

of water during rainy weather. The eggs hatch in only three days. This allows the toad to live in dry
places. The toad has smooth, dry skin. It is usually grayish green with a spade marking on its hind
legs. Adult Great Basin Spadefoot toads eat mostly insects.

and plants. The adults eat insects. They are usually dark gray or brown with darker spots. Their
skin is bumpy and dry. Woodhouse’s toads are nocturnal, which means they are most active at
