  2. Oviparity - Wikipedia

    en.wikipedia.org/wiki/Oviparity

    The egg is not retained in the body for most of the period of development of the embryo within the egg, which is the main distinction between oviparity and ovoviviparity. [1] Oviparity occurs in all birds, most reptiles, some fishes, and most arthropods. Among mammals, monotremes (four species of echidna, and the platypus) are uniquely oviparous.

    Here a Montagu's harrier chick has just hatched from its egg. Animals make use of a variety of modes of reproduction to produce their young. Traditionally this variety was classified into three modes, oviparity (embryos in eggs), viviparity (young born live), and ovoviviparity (intermediate between the first two).

  4. Hatchling - Wikipedia

    en.wikipedia.org/wiki/Hatchling

    The behavior of an amphibian hatchling, commonly referred to as a tadpole, is controlled by a few thousand neurons. [4] 99% of a Xenopus hatchling's first day after hatching is spent hanging from a thread of mucus secreted from near its mouth will eventually form; if it becomes detached from this thread, it will swim back and become reattached, usually within ten seconds.

  6. Embryo - Wikipedia

    en.wikipedia.org/wiki/Embryo

    In animals that hatch from an egg, such as birds, a young animal is typically no longer referred to as an embryo once it has hatched. In viviparous animals (animals whose offspring spend at least some time developing within a parent's body), the offspring is typically referred to as an embryo while inside of the parent, and is no longer ...

  7. Egg tooth - Wikipedia

    en.wikipedia.org/wiki/Egg_tooth

    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. [1] Similar structures exist in eleutherodactyl frogs, and spiders. [2]

    The flagship toys are mini-figures that feature an egg. Pressing a heart on the egg "hatches" an animal or fairy inside. When the line was introduced, the toy was a robotic animal—representing one of various species—that "hatched" itself from an egg.
