Reproduction of Elephants
Habitate of elephants
Elephants usually live in grasslands, but what most people don't know is that you can also find them in places like forest, swamps and the savannah desert.
Elephants eat things like leaves and fruit, so usually they are found where there is plenty of those food sources.
Elephants can have up to 4 -12 offspring, depending on whether it is an African or Asian Elephant. It also depends on how old the Elephant lives to. Elephants have internal fetilisation. they reproduce using cross-fertilisation, so you need two different elephants to produce an offspring. Just one gamete is released in this process.
Elephants have a really long pregnancy, it is 22 months which is the longest pregnancy for mammals. They have such a long gestation period because it needs time for mainly the tusks and trunk to develop properly. Elephants have oviparity which means the baby is developed inside of them.
Mothers, aunts and sisters are very important to calf development. The whole heard slows down so the young can keep up with the rest 0f them.
When the calves are born they watch their mothers eat and they learn what leaves they can and can't eat. Their mother and aunt are the most affectionate contact with the young, offering guidance and assistance.
Calves nurse for the first six months of life. Elephant milk is high in fat
and protein (100 times more than the protein contained in cow’s milk). On average, calves drink about 10 L a day.
Calves begin to experiment with their developing trunks between four and six
months of age by picking grasses and leaves to supplement their diet. Weaning
from milk gradually follows this process. Calves are not completely weaned until
they are over two years of age and may weigh between 850-900 kg.
On average, newborn calves stand about 9 m high and weigh 120 kg at birth. Newborn male African elephants may weigh up to 165 kg .
Newborn Asian elephant calves weigh about 91 kg.
The newborn is helped to its feet by its mother and other females. Calves are
able to stand on their own within minutes of birth. The mother and other females help guide the calf to nurse almost immediately.
The trunk of the calf is still short, so it uses its mouth to nurse. Calves are able to walk within one to two hours of birth. Within two days, calves are strong enough to join the rest of the herd, that is waiting patiently nearby.
Elephants have K-selection parental care because they only have one offspring at a time, elephants can have twins but is very very rare. calf stay with their mother for a 2-3 years. It is Good that te calf stays with the mther becuse
