EGGTOOTH Meaning and
Definition
-
An eggtooth refers to a small, temporary, and often pointed structure found in certain types of animals, particularly birds and reptiles, which helps them hatch from their hard-shelled eggs. This specialized tooth is also known as a "dental egg" or "surgical tooth" due to its function in breaking through the eggshell during the hatching process. The eggtooth is typically located on the upper portion of the beak or snout, and its development varies among species.
The presence of an eggtooth is crucial for embryo survival in oviparous creatures as it aids in piercing the eggshell from the inside. At the embryonic stage, the eggtooth is formed as a small, sharp protuberance made of keratin or dentin, which hardens as the hatching time approaches. Once the animal matures, this tooth is usually shed or absorbed if it does not serve any further purpose.
Eggtooth morphology can differ significantly depending on the species. In birds, it may be a tiny, conical projection, often covered by a small hood-like structure called a caruncle, while in reptiles, it can take the form of a bony protrusion. While it primarily serves as a hatching tool in many species, some animals, particularly reptiles, may retain remnants of the eggtooth throughout their lives, although it no longer has the same function as during the hatching process.
Overall, the eggtooth is an evolutionary adaptation that enables animals to break free from their protective eggshell and embark on their journey into the world.

Etymology of EGGTOOTH
The word "eggtooth" is formed by combining two separate words: "egg" and "tooth".
1. Egg: The term "egg" derives from the Old Norse word "egg", which refers to the oval reproductive body produced by birds, reptiles, fish, and some other animals. The Old Norse word is akin to the Old English word "æg", both of which likely have their roots in the Proto-Germanic word "*ajją". This Proto-Germanic term can be traced back further to the Proto-Indo-European root "*ōwyóm", meaning 'bird, bird's egg.'
2. Tooth: The word "tooth" comes from the Old English word "tōþ", which can be traced back to the Proto-Germanic word "*tanþs".
