Century Dictionary and Cyclopedia
    • ovoviviparous Producing eggs which are hatched within the body of the parent but without placental attachment, so that the young are born alive, yet have not been developed in that direct connection with the blood-vessels of the mother which is characteristic of viviparous animals. Ovoviviparous animals are intermediate in this respect between oviparous and viviparous ones, whence the name. The process is a kind of internal incubation, but not a true gestation or pregnancy. It occurs in some fishes, many reptiles, some insects, as flesh-flies, various worms, and a great many other invertebrates. The carrying of eggs in any special receptacle about the body, from the time they leave the ovary until they hatch, also constitutes ovoviviparity. The implacental mammals, as marsupials, whose young are born very imperfect and then placed in a pouch, are sometimes called ovoviviparous.
