How tall can elephants get
After two days, they can keep up with the herd. This incredible survival technique means that herds of elephants can keep migrating to find food and water to thrive. The elephant's temporal lobe the area of the brain associated with memory is larger and denser than that of people - hence the saying 'elephants never forget'.
There are only around 45, left in the wild. We also support local people to live alongside elephants by protecting their fields from crop-raiding animals using solar powered electric fences and by installing beehives elephants hate bees.

The elephant is the national animal of Thailand. An elephant in the wild can eat anywhere from — pounds of vegetation in a 16 hour period. The intestines of an elephant may be 19 meters in length, or more than 60 feet long. Elephants purr like cats do, as a means of communication. Cows usually give birth to one calf every two to four years.
At birth, elephants already weigh some pounds and stand about three feet tall. Before the Europeans began colonizing Africa, there may have been as many as 26 million elephants. By the early 20th century, their numbers had dropped to 10 million.
Hunting continued to increase. By , their numbers were down to 1. Between and , hunting and poaching put the African elephant at risk of extinction, reducing its population by another half. In the years since, poaching has continued to threaten both species: Savanna elephants declined by 30 percent between and , while forest elephants declined by 64 percent from to as poaching worsened in Central and West Africa.
In , the International Union for Conservation of Nature recognized them as separate species for the first time , listing savanna elephants as endangered and forest elephants as critically endangered. As few as , remain today. Compounding the problem is how long it takes for elephants to reproduce. With reproduction rates hovering around 5 to 6 percent , there are simply not enough calves being born to make up for the losses from poaching.
African elephants are also losing their habitat as the human population grows and people convert land for agriculture and development. Elephants need a lot of room, so habitat destruction and fragmentation not only makes it harder for them to find food, water, and each other, but it also puts them in increased conflict with humans. The decision to recognize African elephants as two separate species is seen as an important step for conservation, as it highlights the different challenges that each species faces.
Scientists hope that the listing will bring more attention to forest elephants, which have often been overlooked by governments and donors when grouped together with more visible savanna elephants. African elephants are protected to varying degrees in all the countries of their geographic range. There have been recent efforts to bring re-legalize the international trade in ivory, but those so far have failed.
Conservation groups and governments have worked to set aside land for wildlife— including corridors that connect those protected lands. Still, researchers believe that up to 70 percent of elephants' range is on unprotected land. To curb poaching, stopping the illegal trade is key. Advocates have launched campaigns that address both the supply side poaching and the demand side people who buy ivory.
Since the ban went into effect, public demand for ivory seems to have fallen. On the supply side, protecting elephants from poaching also requires a local approach. In , a study showed that the suffering of elephants is tied to that of the humans living nearby: Regions with high levels of poverty and corruption are more likely to have higher poaching rates.
An elephant may also spray water on its ears, which also will cool down the blood before it returns to the rest of the body. The ears of an African elephant are enormous. Each ear is about six feet from top to bottom and five feet across. A single ear may weigh as much as one hundred pounds.
When an elephant is angry or feels threatened, it may respond by spreading its ears wide and facing whatever it may perceive as a threat. Both are born with small brain masses. Similar to a human being, there is considerable growth and development in the brain as a young elephant grows up. As the mass of the brain increases so does the learning ability of young elephants. Brain size provides a rough measure of mental flexibility; large mammalian brains are associated with superior intelligence and complex social behavior.
The skull, parts of which are six inches thick, contains many air spaces making the inside appear something like a honeycomb or sponge. This adaptation has allowed the skull to grow to a large size without enormous weight. The legs of an elephant are in an almost vertical position under the body, like the legs on a table. This design provides strong support for the massive body and huge weight that the legs have to carry.
It also allows elephants to sleep standing up without the risk of their legs buckling. Elephant skin lacks moisture so it must be loose, especially around the joints, to provide the necessary flexibility for motion. The skin of the African elephant is more wrinkled than that of the Asian elephant. The pink or light brown areas of skin on some Asian elephants are from a lack of pigmentation. This lack of pigmentation can be influenced by genetics, nutrition, habitat and age.
