Pipping (animal Behavior)
An egg tooth is a temporary, sharp projection present on the bill or snout of an oviparous animal at hatching. It allows the hatchling to penetrate the eggshell from inside and break free. Birds, reptiles, and monotremes possess egg teeth as hatchlings. Similar structures exist in Eleutherodactyl frogs, and spiders. Birds When it is close to hatching, a chick uses its egg tooth to pierce the air sac between the membrane and the eggshell. This sac provides a few hours' worth of air, during which time the chick hatches. When a chick is ready to hatch from its egg, it begins the process of "pipping"; forcing the egg tooth through the shell repeatedly as the embryo rotates, eventually cutting away a section at the blunt end of the egg, leaving a hole through which the bird may emerge. Some species, including woodpeckers, have two egg teeth; one on both the upper and lower bill. After time the egg tooth falls off or is absorbed into the growing chick's bill. Some precocial species s ...

In some schools, truancy may result in not being able to graduate or to receive credit for classes attended, until the time lost to truancy is made up through a combination of detention, fines, or summer school. Truancy is a frequent subject of popular culture. '' Ferris Bueller's Day Off'' is about the title character's (played by Matthew Broderick) day of truancy in Chicago with his girlfriend and best ...
