Yes, kangaroo is a noun, a singular, common, concrete noun; a word for a mammal, a word for a thing.
Of course. There are close to seventy recognised and described species of kangaroos, from the large Red kangaroo and Grey kangaroo to the tiny Musky rat-kangaroo. Kangaroo species also include wallabies, wallaroos, potoroos and bettongs. Even tree kangaroos exist. Kangaroos are native to Australia, while tree kangaroos are also found on the island of New Guinea.
The Red Kangaroo is also known as the Marloo or Plains Kangaroo. The female is sometimes referred to as a 'Blue Flier'. The scientific name is Macropus rufus.
