What is a Kangaroo Rat?
The combination of the names ‘Kangaroo’ and ‘rat’ for a particular creature sounds a bit weird or rather hilarious to the ear. You might wonder if this creature shares both features of a Kangaroo and a Rat. It would be amazing if it did. Despite its name and mouse-like appearance, the Kangaroo rat is neither a rat nor a mouse.
What family does it belong to?
The Kangaroo rat is a part of the Heteromyidae family – the pocket gopher.
The Kangaroo rat gets its name as it moves in a bipedal fashion – hopping along on its hind legs like a kangaroo but cultivated this mode of locomotion unaided, like many other clades of rodents (e.g. dipodids and hopping mice).
Kangaroo rat is a species of rat that is classified under the group of desert rodents. 20 kangaroo rat species are native to North America.
Kangaroo rats inhabit dry, arid and semi-arid habitats such as deserts, sandy and rocky areas.
They can also dwell in habitats such as grasslands and scrublands, located at several altitudes.
A major threat to the existence of kangaroo rats is the loss of habitat due to intensified human activity. This can make kangaroo rats extinct in the near tomorrow.
Certain species known as giant kangaroo rats are documented as endangered due to these increased human activities.
What is the largest Kangaroo rat species?
The giant kangaroo rat, is the largest of over 20 species of kangaroo rats, which are small members of the rodent family, scaling about 15 cm (5.9 in) in length, containing its long, tufted tail. It is tan or brown.
The other species of the kangaroo rats have large eyes, a big-sized head, and a long, stable hind leg which helps them to hop faster.
Kangaroo rats are in no way as big as Kangaroo.
What is the best time for the Kangaroo rats to mate?
Kangaroo rat wallows in the sand to remove dirt and keep its fur clean. They mate in the summer, after the season of heavy rains. Kangaroo rats have a promiscuous mating system.
Their reproductive output is at the peak during the summer due to high rainfalls. During droughts and food shortages, only a few females will spawn.
It seems kangaroo rats can examine their local situations and tailor their reproductive undertakings accordingly.
What month do Kangaroo rats breed?
Kangaroo rats breed between February and May and give birth to two or three litters per year. Before they mate, the male and female will execute nasal-anal circling until the female halts and permits the male to clamber her.
A Kangaroo rat female will permit several males to clamber her within a short period, maybe to guarantee greater opportunities for producing offspring. This is intelligent behavior from this little creature.
Mating in banner-tailed kangaroo rats comprises more chasing and foot drumming in the male before the female permits him to mate. Banner-tailed kangaroo rats mate on mounds and the healthier males drive away competing males.
The kangaroo rats have a range gestation period of 22–27 days. The young Kangaroo rat is given birth in a fur-lined nest in the burrows. They come out blind and without hair.
For the first week after delivery, young kangaroo rats crawl formulating their hind legs in their second or third week after delivery. At this time, the young kangaroo rat becomes independent.
A banner-tailed kangaroo rat stops depending on his mum after 22 and 25 days. Offspring stay in the mound for 1-6 more months in the maternal caches.
