The Emu (pronounced /ˈiːmjuː^/), Dromaius novaehollandiae, is the largest bird native to Australia and the only extant member of the genus Dromaius. It is also the second-largest extant bird in the world by height, after its ratite relative, the ostrich. The soft-feathered, brown, flightless birds reach up to 2 m (6.5 ft) in height. The Emu is common over most of mainland Australia, although it avoids heavily populated areas, dense forest and arid areas. Emus can travel great distances at a fast, economical trot and, if necessary, can sprint at 50 km/h (30 mph) for some distance at a time. They are opportunistically nomadic and may travel long distances to find food; they feed on a variety of plants and insects.

Tulipa, commonly called tulip, is a genus of about 150 species of bulbous flowering plants in the family Liliaceae. The native range of the species includes southern Europe, north Africa, and Asia from Anatolia and Iran in the west to northeast of China. The centre of diversity of the genus is in the Pamir and Hindu Kush mountains and the steppes of Kazakhstan. A number of species and many hybrid cultivars are grown in gardens, used as pot plants or as fresh cut flowers. Most of the cultivated species, subspecies and cultivars of tulip are derived from Tulipa gesneriana.

The frog is an amphibian in the order Anura (meaning “tail-less”, from Greek an-, without + oura, tail), formerly referred to as Salientia (Latin saltare, to jump). The name frog derives from Old English frogga,(compare Old Norse frauki, German Frosch, older Dutch spelling kikvorsch), cognate with Sanskrit plava (frog), probably deriving from Proto-Indo-European praw = “to jump”.

The cat (Felis catus), also known as the domestic cat or house cat to distinguish it from other felines, is a small predatory carnivorous species of crepuscular mammal that is valued by humans for its companionship and its ability to hunt vermin, snakes and scorpions. It has been associated with humans for at least 9,500 years
