- Cassowaries are part of the ratite group, which also includes the emu, rheas, ostriches, and kiwi, in addition to the extinct moas and elephant birds. Three in existence species are recognized, and one destroyed. Characteristically, all cassowaries are shy birds that are found in the deep forest. They are skillful at disappearing long before a human knows they were there.
- Females are larger and more intensely colored than the males. Adult southern cassowaries are 1.5 to 1.8 m (5–6 ft) tall, Even if some females may reach 2 m (6.6 ft), and weigh 58.5 kg (130 lb).
- All cassowaries encompass feathers that consist of a shaft and loose barbules. They do not have tail feathers or a preen gland. Cassowaries comprise small wings with 5–6 large remnants. These are condensed to stiff, keratinous quills, resembling porcupine quills, with no barbs.
