Oviparous animals are animals that lay Egg biology eggs , with little or no other embryo nic development within the mother. This is the Biological reproduction reproductive method of most fish , amphibia ns, reptile s, all bird s, the monotreme s, and most insect s and arachnid s. Land dwelling animals that lay eggs, often protected by a shell, such as reptiles and insects, do so after having completed the process of internal fertilization . Water dwelling animals, such as fish and amphibians, lay their eggs before fertilization, and the male lays its sperm on top of the newly laid eggs in a process called external fertilization . Almost all non oviparous fish, amphibians and reptiles are ovoviviparity ovoviviparous , i.e. the eggs are hatched inside the mother s body or, in case of the sea horse inside the father s . The true opposite of oviparity is vivipary placental viviparity , employed by almost all mammals the exceptions being marsupial s and monotreme s . There are only five known species of oviparous mammals four species of Echidna and the Platypus .

Unreferenced stub auto yes date December 2009 Ovoviviparity , ovovivipary , or ovivipary , is a mode of reproduction in animal s in which embryo s develop inside egg biology egg s that are retained within the mother s body until they are ready to hatch. Ovoviviparous animals are similar to viviparous species in that there is internal fertilization and the young are born live, but differ in that there is no placenta l connection and the unborn young are nourished by egg yolk the mother s body does provide gas exchange respiration . Ovoviviparity is employed by many aquatic life forms such as some fish , reptile s, and invertebrate s. The young of ovoviviparous amphibians are sometimes born as larva e, and undergo Metamorphosis biology metamorphosis outside the body of the mother. In Elasmobranchii sharks and rays , the term ovoviviparity has recently been deprecated in favor of aplacental viviparity . Authors may regard the two terms as synonymous, or equate ovoviviparity only with aplacental yolk sac viviparity, in which the embryos are solely sustained by yolk as opposed to secondary provisioning by their mother in the form of uterine milk , such as in the stingray s, or unfertilized eggs, such as in the Lamniformes mackerel sharks .

In mammal s, internal fertilization is done through mating copulation , which involves the insertion of the penis into the vagina . Some other higher vertebrate animals most reptile s, most bird s, and some fish reproduce internally, but their fertilization is cloaca l. The union of spermatozoa of the parent organism. At some point, the growing egg biology egg or offspring must be expelled. There are three general ways of doing this Oviparity Oviparous organisms, including most insect s and reptiles, monotreme s, and all birds lay eggs that continue to develop after being laid, and hatch later. Vivipary Viviparous organisms, including almost all mammals such as whale s, kangaroo s and human s bear their young live. The developing young spend proportionately more time within the female s reproductive tract. The young are later released to survive on their own, with varying amounts of help from the parent s on the species . Ovoviviparity Ovoviviparous organisms, like the garter snake , and the Madagascar hissing cockroach , have eggs with Eggshell shells that hatch as they are laid, making it look like live birth . Most species of land animals reproduce by internal fertilization. For example All reptiles, such as the snake and turtle reproduce by internal fertilizations. Males and females usually have an opening called the cloaca through which semen, urin and feces can be released. During mating, the male and female join their cloacas. The male releases semen into the female s cloaca. The spermatozoe then travel up a canal to reach the ova.

Image Poicephalus senegalus egg tooth two weeks 21July07.JPG right thumb A Senegal Parrot chick at about 2 weeks after hatching. The egg tooth is near the tip of its beak on the upper mandible. In some Oviparity egg laying animal s, the egg tooth is a small, sharp, cranial protuberance used by offspring to break or tear through the egg s surface during hatching. It is present in most bird s and reptile s, and similar structures exist in monotreme s, Eleutherodactylus Eleutherodactyl frog s, and spider s. Some lizard s and snake s develop a true tooth that is shed after use other reptiles and birds generally develop an analogous epidermal horn that is reabsorbed or falls off. Birds In birds, the process of breaking open the eggshell is commonly referred to as pipping . ref cite web url http www.merriam webster.com dictionary Pipping title Definition and etymology of pipping publisher Webster s Dictionary accessdate 2008 04 03 ref Baby birds have a pipping muscle on the back of their necks. It is this muscle which gives them the strength to force the egg tooth through the inner membrane of the eggshell. When a baby bird becomes too large to absorb oxygen through the pores of its eggshell, it uses its egg tooth to peck a hole in the air sac located at the flat end of the egg. This sac provides a few hours worth of air, during which the baby bird breaks through the eggshell to the outside. The egg tooth falls off several weeks after hatching. Kiwi s lack an egg tooth, instead using their legs and beak to break through a relatively thin eggshell. The superprecocial megapode s possess an egg tooth in their early embryonic development, but instead use their claws during hatching.
