Occasionally, a few rare breeds from the exotic feline species can be born with child.

I think so! Visit: http://www.bbc.co.uk/nature/animals/mammals/

All animals move at some point in their life.  However, animals like sponges, hydras, anemones and coral are stationary in their adult form.

The eggs of fish are fertilized either externally or internally, depending on species. The female usually lays the eggs and the embryos in the eggs develop and hatch outside her body. This kind of fish are called oviparous fish. Oviparous fish develop being obtaining food from the yolk in the egg. Salmon, for example, are oviparous. Ovoviviparous fish keep the eggs inside of the mother's body after internal fertilization. Each embryo develops in its own egg. The young are "born alive" like most mammals. Some species of fish, such as various sharks, are viviparous. Viviparous fish allow their embryos to stay in the mother's body like ovoviviparous fish. However, the embryos of viviparous fish obtain needed substances from the mother's body, not through material in the egg. The young of viviparous species are also "born alive".

No.  If it was possible, don't you think there's be a bunch of little monsters (literally) running around.\n\nHuman and animal sperm and egg are incompatible.  For example, sperm from a horse or a dog or something is incapable of fertilizing a human egg.  Thus, no child is born.\n\nA human egg is designed to only accept human sperm.  Animal sperm couldn't penetrate into the egg even if they wanted to, without specialised scientific equipment.  At the same time, human sperm is designed to only be able to penetrate a human egg, and does not posess the qualities necessary to get into an animal egg.\n\nThe only species that can cross breed are a horse and a donkey, which creates a mule.  However, mules are sterile, which means they are incapable of creating thier own offspring.\n\n\n\n\nOh, and as a response to the first answer, scientists HAVE found a way that they believe would work, but have deemed it unethical, and illegal to experiment further.  Why on Earth would we want to purposefully create little freaks for anyway?

The father of a liger is a lion and its mother is a tiger.  Ligers tend to be larger than either of their parents.  The parents of a tigon are a male tiger and a female lion.  Tigons tend to be smaller and more wirey than either of their parents.  Both female ligers and female tigons can be fertile, but males are always sterile.

"Breeding" looks like it fits the bill.  \n:-)  Hope this helps!

Yes.  A whale is a mammal, and one characteristic of all mammals is that they reproduce sexually.

Many bats also delay implantation after the eggs are fertilized.  There are also several mammal groups that have delayed fertilization, holding viable sperm for months until they are ready to begin gestation, and then an egg cell is fertilized.\n\nThis is possible in placental mammals where the egg cell is kept internal, and doesn't have a shell to protect it from the outside environment.  I doubt that it would be possible in, for example, birds, where once the egg is formed it's pretty much a done deal, and development goes ahead regardless of outside conditions.

Not a human male... some aquatic species (and probably others...) have the males carry the baby upon fertalization

lions and tigers are one i know of. aka ligers/tygons. i believe wolves/dogs can be too. i would assume that there could be a lot more possibilities as long as they are in the same family of animal.

nope... they have a difference level of chromosomes,\n\n\nthey more than liekly could try.. but the results would be more than likely dead and birth from physical problems such as no lungs, or no heart etc..\n\ndifferent animals have maanged to mate ouside thier chromosome levels, such as the donkey and horse, and the lion and tigers (Ligers).. normally these animals do not last a full age and have birth defects.

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

No. Where would I find such an animal?
