They usually live in a group consisting of members up to 50–60. , Historically, elephants were considered formidable instruments of war.  Historically, numerous cultures made ornaments and other works of art from elephant ivory, and its use rivalled that of gold. side of the face. Larger ear surfaces contain more capillaries, and more heat can be released. Aside from the protective function that skin plays for all animals, there are several unique characteristics of an elephants skin worth noting. Two biomechanical features can trigger these traveling wave patterns, which are a low fundamental frequency and in the vocal folds, increasing longitudinal tension. Elephants are the largest living terrestrial animals. Ptolemy, who was one of Alexander's generals, used corps of Asian elephants during his reign as the ruler of Egypt (which began in 323 BC). The Asian elephant has only one, and relies more on wrapping around a food item and squeezing it into its mouth.

Asian males can have tusks as long as Africans', but they are usually slimmer and lighter; the largest recorded was 302 cm (9 ft 11 in) long and weighed 39 kg (86 lb). They have been observed to have "nursing units" and "juvenile-care units". Elephant teeth have loop-shaped dental ridges, which are thicker and more diamond-shaped in African elephants. , The second radiation was represented by the emergence of the gomphotheres in the Miocene, which likely evolved from Eritreum and originated in Africa, spreading to every continent except Australia and Antarctica. In a population in southern India, males first enter musth at the age of 15, but it is not very intense until they are older than 25.

The temporal gland is a huge organ which weighs about 1.5 kg, producing a heavily scented secretion which trickles down the A durable nictitating membrane protects the eye globe. The skull grew larger, especially the cranium, while the neck shortened to provide better support for the skull. , Play behaviour in calves differs between the sexes; females run or chase each other while males play-fight. For the African elephants, tusks are present in both males and females, and are around the same length in both sexes, reaching up to 300 cm (9 ft 10 in), but those of males tend to be thicker. As a piece of living tissue, a tusk is relatively soft; it is as hard as the mineral calcite. Teeth are not replaced by new ones emerging from the jaws vertically as in most mammals. Elephants killed around 300 people between 2000 and 2004 in Jharkhand while in Assam, 239 people were reportedly killed between 2001 and 2006. Cartilage divides the nostrils at the base.

Before plastic was invented, elephant tusks and their ivory were used to make cutlery handles, musical instruments, billiard balls and piano keys.  Elephants tend to have high numbers of parasites, particularly nematodes, compared to other herbivores. A. Schulte. , In 2008, the IUCN listed the Asian elephant as endangered due to a 50% population decline over the past 60–75 years while CITES lists the species under Appendix I. This has been observed in 54% of individuals in UK zoos. Feld stated that these practices are necessary to protect circus workers and acknowledged that an elephant trainer was reprimanded for using an electric shock device, known as a hot shot or electric prod, on an elephant. , Bulls engage in a behaviour known as mate-guarding, where they follow oestrous females and defend them from other males.

Unlike most mammals, which grow baby teeth and then replace them with a single permanent set of adult teeth, elephants are polyphyodonts that have cycles of tooth rotation throughout their lives. , In both Myanmar and Thailand, deforestation and other economic factors have resulted in sizable populations of unemployed elephants resulting in health problems for the elephants themselves as well as economic and safety problems for the people amongst whom they live.  In earlier times, elephant tusks weighing over 200 pounds (more than 90 kg) were not uncommon, though it is rare today to see any over 100 pounds (45 kg). Suckling after two years may serve to maintain growth rate, body condition and reproductive ability. , The social circle of the female elephant does not necessarily end with the small family unit. Copulation lasts about 45 seconds and does not involve pelvic thrusting or ejaculatory pause. Only when Elephas disappeared from Africa did Loxodonta become dominant once again, this time in the form of the modern species. This individual was even able to score a high accuracy rating when re-tested with the same visual pairs a year later. The mammary glands are about the same size and shape as the breast of a woman.

Bulls are powerful and aggressive to be threatened towards a predator and serve extra protection to the herd nearby.  Asian elephants prefer areas with a mix of grasses, low woody plants, and trees, primarily inhabiting dry thorn-scrub forests in southern India and Sri Lanka and evergreen forests in Malaya. At the same time, improvements in lip and leg coordination occur. A.  Elephants can suck up water both to drink and to spray on their bodies. soil. After 1987, losses in elephant numbers accelerated, and savannah populations from Cameroon to Somalia experienced a decline of 80%. Vocal production mechanisms at certain frequencies are similar to that of humans and other mammals and the laryngeal tissues are subjected to self-maintained oscillations. Allomothers are typically two to twelve years old. Families may associate and bond with each other, forming what are known as bond groups which typically made of two family groups. After bathing, the elephant will usually use its trunk to blow dust onto its body and this dries into a protective crust. In Sumatra, elephants have been associated with lightning. Question 20.
