Do only male or female elephants have tusks?  Or do they both?

In the case of the African elephant (Loxodonta africana) both sexes have tusks, but only male Asian elephants (Elephas maximus) have them.

No. Ivory from both Indian and African elephants, as well as ivory from mammoths and mastodon. The tusks, or upper incisors, of these animals are used. They can have a cross section of up to 20cm (8"), and be up to 2.5m (almost 3 yards) long. They are oval in cross section, and are made up of a hard, dense tissue called dentin, which is made up of 70% inorganic material, and 30% collagen. Unlike human teeth, elephant tusks do not have an enamel coating. They do have a cementum layer, however; ivory dealers refer to this as the "bark" or the "rind". Occasionally this layer is retained on a piece of worked ivory. One-third to one-half of an elephant tusk is hollow.\n\nGrowth occurs as layer upon layer of calcified tissue is deposited on the interior of the tusk; you can see these concentric oval growth lines (called the Lines of Owen) in cross section. If you cut ivory lengthwise, these lines appear triangular. Fine and even near the hollow of the tusk (the pulp cavity), these lines become wavy and have milky areas between them as you get closer to the outside of the tusk.\n\nUnique to elephant ivory are the Lines of Retzius. These fine intersecting lines are visible in cross section, and give an engine-turned effect (intersecting lines with a diamond shape between them).\n\nGenerally, elephant ivory has a fine, even grain and is easily carved in all directions. It can be thinly cut (i.e. for piano keys), and can be more deltcately carved than bone. This ivory is often painted or stained, dyed, and gilded. When cut, the pores of the ivory fill with an oily substance, which helps the ivory polish up nicely.

Most non-mammalian groups do. In mammals, the males are larger, but that is mostly realted to the fact that they fight for the attention of females and the chance to mate, so natural selection makes them bigger than the females.\nIn most other groups however, amphibians, reptiles, most insects, arachnids, many crustaceans and other invertebrates, the female is usually larger based on the simple fact that she must caryy eggs with her. Eggs are  much more bulky that live young, so the female must be larger in order to carry such a weight around. So, to answer your question, there are thousands, potentially millions of species that have larger feamles than males!\n\nlarge female, tiny male:\nhttp://bugguide.net/node/view/44206\n\nhope this answers your question!

I agree, you even see this in animal behaviour. Animals like elephants take care of their young and only kill when in danger, or when they feel danger. Elephants normally don't kill humans but because of lots of poachers, they do now. Elephant’s memories are apparently very good. We are of course much more evolved than elephants.

Elephants because they are stong and can be very agressive. They would use their tusks to stab the polar bear if they don't trample it. Normly, though, most beings just run away at the site of the immense size of an elephant. I'm not saying that the polar bear will run away, but it would probably stand down and be dicouraged.

Elephants have evolved with tusks as the elongated teeth enable the elephants to manipulate and hold items with the trunk and tusks.  They can pick up quite small items and rotate in front of their lips using the trunk and tusk combination to strip off the leaves etc.  They also use the trunk to strip the bark off of trees,scrape earth up to dig water holes and mineral scrapes, and for defence - although their large size makes them fairly predator proof.\nIndian elephants have smaller tusks than African elephants because they have evolved as a jungle species and the bigger tusks would get in the way in the undergrowth etc, plus the lusher vegetation means they do not need to scrape for water etc.

Elephants protect themselves with their tusks, which can be up to 6 feet long.

Husbands.  (haha) \nI believe female octopusses (what IS the plural? Octopi?) only mate once in their lives. They die caring for their babies.\nMany animals are seasonal and only have one litter a year, depending on the climate.

No, male kangaroos (boomers) don’t have pouches. Only females do.

What about an elephant?

These two species may be relatively close in genetical terms, but they live in different continents: Elephas maximus in Asia, Loxodonta africana in Africa. \nHowever, when individuals of different species are brought to live together in artificial habitats, anomalous behavior can occur, including mating. \nThere was at least one hybrid African-Asian elephant that was born in 1978 in an English zoo (see link).

I believe the female frog is bigger. You see males bigger than females is unique among mammals. There are ofcourse exceptions. But in insects, birds, fish, reptiles, and amphibians (such as a frog), it is the females that are generally larger. Also males will engage in most of the vocalizations to attract females. This is the "ribit" croaking a frog makes. Females will engage in a reciprocal call but only if they are in the area, it's usually the males or groups of males.

Yep, most animals have vocalisations that differ between males and females.\n\nThat may be harder to pick for animals that we have bred to be highly variable like dogs, but even there within a specific breed it is usually possible to differentiate the males and females by their bark.\n\nBut certainly it is easy to differentiate roosters from hens, bulls from cows or stallions from mares based upon just the sound alone.\n\nBy the time we get to animals like frogs or cicadas it becomes extremely easy to do because only the males make any sound. The females are mute.

Elephants have the longest gestation of all mammals. Pregnancy lasts about 22 months.

No. Besides humans, only other great apes exhibit menstrual cycles, in contrast to the estrus cycle of most mammalian species.

It is just called a female.\nIf you want to be really sure check this site.\nhttp://www.enchantedlearning.com/subjects/animals/Animalbabies.shtml

Why do you want to know this? Since they are mammals, they also mate for life. If you are asking if they are monogamous, they are not. The female does not form a permanent bond with a male. So, does this answer the question?
