Pirmajos ķenguru aprakstos tiek rakstīts, ka tie ir dzīvnieki ar briežu galvām bez ragiem, stāv uz divām kājām kā cilvēki un lec kā vardes. Pirmais ķengurs, kas tika aizvests uz Eiropu, lai to publiski izrādītu, bija Džona Gora 1770. gada medību trofeja.[1] Uz Eiropu tika atvesta dzīvnieka āda un galvaskauss, un demonstrācijai tika pagatavots izbāzenis. Turklāt taksidermists, kas strādāja pie izbāzeņa, nekad dzīvu ķenguru nebija redzējis. # Izskats Īstie ķenguri ir vislielākie somaiņi ķenguru dzimtā un somaiņu infraklasē. Tiem ir lielas, spēcīgas pakaļkājas un lielas pēdas, kas piemērotas lēkšanai. Tiem ir gara, muskuļota aste, kas notur ķenguru līdzsvarā un pret kuru ķengurs atspiežas stāvot. Ķenguriem ir salīdzinoši maza galva. Kā visiem somaiņiem ķenguru mātītēm uz vēdera ir soma, kurā tiek nēsāts līdzi mazulis. # Uzvedība Ķenguri var sasniegt ievērojamu ātrumu, lecot uz divām kājām. Pastaigas solis ķenguram ir apmēram 20—25 km/h, bet bēgot īsā distancē tas sasniedz 70 km/h. Distancēs līdz 2 kilometriem, ķengurs var skriet ar ātrumu 40 km/h.[2] Lēciens ir 6—7 metrus garš, bet no paugura uz leju tēviņš var aizlēkt līdz 12 metriem. Augstumā tēviņš bez piepūles var pārlēkt 2,5 m žogu. Aizstāvoties ķengurs sper ar pakaļkājām. Trieciens ir tik spēcīgs, ka tas cilvēkam var salauzt galvaskausu. Ķenguri bieži, bēgot no suņiem un dingo, glābiņu meklē kādā ūdenstilpē. Iebridis līdz krūtīm ūdenī, tas stabili nostājas uz pakaļkājām, atbalstoties pret asti, un gaida vajātāju. Ja dingo tam tuvojas, tad ķengurs to saķer ar priekškājām un slīcina, turot tā galvu zem ūdens tik ilgi, kamēr suns aizrijas ar ūdeni.[3] Vidējais ķengura dzīves ilgums savvaļā ir 4—6 gadi.[4]

- [ ] Tests - A - B - C | Month | Savings | | -------- | ------- | | January | $250 | | February | $80 | | March | $420 | Kangaroos are marsupials from the family Macropodidae (macropods, meaning "large foot"). In common use, the term is used to describe the largest species from this family, the red kangaroo, as well as the antilopine kangaroo, eastern grey kangaroo, and western grey kangaroo.[1] Kangaroos are indigenous to Australia and New Guinea. The Australian government estimates that 42.8 million kangaroos lived within the commercial harvest areas of Australia in 2019, down from 53.2 million in 2013.[2] As with the terms "wallaroo" and "wallaby", "kangaroo" refers to a paraphyletic grouping of species. All three terms refer to members of the same taxonomic family, Macropodidae, and are distinguished according to size. The largest species in the family are called "kangaroos" and the smallest are generally called "wallabies". The term "wallaroos" refers to species of an intermediate size.[3] There are also the tree-kangaroos, another type of macropod which inhabit the upper branches of trees in the tropical rainforests of New Guinea, far northeastern Queensland, and some of the islands in the region.[4] A general idea of the relative size of these informal terms could be: - wallabies: head and body length of 45–105 cm and tail length of 33–75 cm; the dwarf wallaby (the smallest of all known macropod species) is 46 cm long and weighs 1.6 kg; - tree-kangaroos: ranging from Lumholtz's tree-kangaroo: body and head length of 48–65 cm, tail of 60–74 cm, weight of 7.2 kg (16 lb) for males and 5.9 kg (13 lb) for females; to the grizzled tree-kangaroo: length of 75–90 cm (29.5–35.5 in) and weight of 8–15 kg (18–33 lb); - wallaroos: the black wallaroo (the smaller of the two species) with a tail length of 60–70 cm and weight of 19–22 kg (42–49 lb) for males and 13 kg (29 lb) for females; - kangaroos: a large male can be 2 metres (6 feet 7 inches) tall and weigh 90 kg (200 lb). Kangaroos have large, powerful hind legs, large feet adapted for leaping, a long muscular tail for balance, and a small head. Like most marsupials, female kangaroos have a pouch called a marsupium in which joeys complete postnatal development. Because of its grazing habits, the kangaroo has developed specialized teeth that are rare among mammals. Its incisors are able to crop grass close to the ground and its molars chop and grind the grass. Since the two sides of the lower jaw are not joined or fused together, the lower incisors are farther apart, giving the kangaroo a wider bite. The silica in grass is abrasive, so kangaroo molars are ground down and they actually move forward in the mouth before they eventually fall out, and are replaced by new teeth that grow in the back.[5] This process is known as polyphyodonty and, amongst other mammals, only occurs in elephants and manatees.
