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, all dinosaur 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, dinosaurs 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 fertilization. Males and females usually have an opening called the cloaca through which semen, urine and feces can be released. During mating, the male and female join their cloacas. The male releases semen into the female s cloaca. The spermatozoa 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 Chicks 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 chick 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 chick breaks through the eggshell to the outside. The egg tooth falls off several days 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.
