The larger and more complex an animal is, the longer it takes them to develop. An elephant's trunk contains over 100,000 muscles, and the newborn calf can weigh around 300 pounds. It not only takes a long time to develop all of those individual parts, but it takes some time to put on 300 pounds worth of weight.
Another reason is because the massive amounts that elephants consume, they have slower reproduction rates to help control their own population. This keeps the population from getting too large and eating more than the environment can support. In natural circumstances, this is a good thing. However, with the problem of poaching, it means they are having trouble keeping their population up.
An Elephant is much bigger so it takes longer for the formation of the elephant.
A mouse is smaller and so it takes less time for the creation of the mouse.
You could state it like this. The size is directly proportionate to the gestation period.
cause mouse is a beast that's why
because their babys are so big
17 to 45 days.
Gestation and pregnancy are synonyms, although gestation is generally used for non-human animals (particularly non-pet animals) and pregnancy is generally reserved for humans (and increasingly companion or pet animals).
The gestation for mice is approximately 19-21 days.
Mice have a gestation period of 20 days. They can have 3-14 babies.
The gestation period for a mouse is generally 20-24 days.
The period of time a mammal is pregnant (gestation period) ranges depending on the species. The species of mammal with the longest gestation period is the Asiatic Elephant with a maximum gestation period of 760 days. The shortest of American Opossum with a minimum of 8 days.
The gestation period of mice is around 20 days.
The gestation period of mice is around 20 days.
A mouse's gestation period is around 20 days.
A Variety of mice have the same gestation period.(field, house, fancy, and meadow voles). Have a gestation period of 21 days. From Insemanation through incubation and birth is a total of 21 days. Normally a mouse will give birth from 6- 10 Pinkies(newborn Mice) however it is not unheard of to see upto 20 pinkies at birth. However when this happens likelyhood of a 100% survival rate is rare. Along with birth defects.(no eyes, mouth, ears, and or appendages).
Smaller mammals have shorter gestation periods. If a mother mouse kept her young inside her uterus/placenta for too long, the young would become so big that the mother would die. Also, mice have very short lifespans due to their heavy predation and small size, so a female mouse needs to produce as many young as possible in her short life in order to keep the species from going extinct. A short gestation period increases fertility in that more litters can be produced in the same amout of time. Thus, mice have evolved very short gestation periods. Although a mouse's gestation period is only about 20 days, there are some mammals, such as certain opossums, whose gestation periods are even shorter.
No, elephants and mice are not the same species. The only thing that is similar between them is the fact they are both mammals.
