Longest Mammal Gestation Period\nThe Asiatic elephant (Elephas maximus) has an average gestation period of 650 days (more than 21 months), and can be pregnant for up to 760 days – more than two and a half times as long as humans.\n\nsource: http://www.guinnessworldrecords.com/index.asp?id=51186 \n\nThe longest gestation period known in mammals is that of the African elephant (Loxodonta Africana). These elephants carry their babies in the womb for about 660 days or 22 months. Camels and giraffes carry their babies for about 400 days. Other animals that have gestation periods closest to that of humans are: dolphins - 276 days, chimpanzee - 237 days and cattle - 280 days.\n\nsource: http://scienceiq.com/ShowFact.cfm?ID=494

Yes, pregnancy can happen. Sperm can live, mmmm, I forget, but I want to say 24-48 hr.\n\nI stand corrected, can't live out in the air, I guess, but I do know they sure can swim!

A heffalump!\nBe afraid, be very afriad!\nhttp://disney.wretch.cc/mvdata/data/Pooh_Heffalump_Movie.jpg\n\nAs you probably know, the largest known animal on Earth is the blue whale. But most scientist believe that the blue whale is also the largest amimal that has ever lived.\nThey can weigh over 200 tons, so how can you beat that?\n\nBut as far as land animals go: the African elephant is the largest!\n\nAn extinct species of the rhinoceros called Baluchitherium grangeri was around 30 tons. That would be the largest land-dwelling mammal ever.\nThe largest dinosaur was the sauropod.\nhttp://www.dinosaurios.net/rama/rm_sale/rm_diplo01g.jpg

DEFINITELY a dolphin, it is the smallest aquatic mammal. otters are not wholely aquatic. and sea monkeys sea lions etc are not mammals. whales are the largest mammals.

The Blue whale has the longest penis of any animal that ever existed. It's 6 feet long! This is because it is the largest ever animal.\nThe barnacle has the longest penis in relation to it's own size, and it has TWO! Each one is 40 TIMES the length of it's body. \nThis is because the adult barnacle is glued to a rock, but likes to play the field.\nI hope that you find this answer most helpful.

Now the only mammals that do lay eggs are the platypus and the two species of echidna.\n\nI hope this helps.

Dear naive one:\n\nIn my opinion, you should revise your question if you want one to answer it. The correct revision of your question would be "What is the fastest running animal?". Have you ever heard of grammar classes? If you are asking me what the fastest animal on earth is, I assume it is the cheetah( unless there is an faster animal that man has not yet discovered). Cheetah comes from the Hindi word meaning "spotted one" and/or from the Sanskrit word, "chitraka".\nBeing one the fastest known terrestrial(terra=earth)animals, the cheetah can travel about 60 miles per hour. If you do not remember what your pedants taught you at school, I highly suggest that you take a vitamin supplement called "Mega Memory". To my knowledge, it does not hurt to try new things. I have completed my job of educating you. It is interesting to note that to my knowledge most seven-year-olds know that the cheetah is the fastest land animal.\nGood bye.\nSincerely, \nClark

Prototheria = the monotremes, only egg-laying mammals. Echidnas and platypus.\n\nMetatheria = the marsupials, mammals that carry their young in a pouch (well, some don't have pouches, the important characteristic is that their uterine gestation is very short).\n\nEutheria = placental mammals, with full development of the young within the mother's womb.
