ovoviviparity การใช้

• Females of the species give birth to live young through ovoviviparity.
• Reproduction is aplacental viviparous, which was before called ovoviviparity.
• Viviparity and ovoviviparity have evolved in many extinct clades of reptiles and in squamates.
• The terms " Ovoviviparity " or " a placental viviparity " have been deprecated because they encompass several unrelated modes of reproduction.
• Many cichlids are mouthbrooders, with the female ( or more rarely the male ) incubating the eggs in the identical with, ovoviviparity.
• Ovoviviparity is a mode of reproduction in which embryos develop inside eggs that remain in the mother's body until they are ready to hatch.
• The female retains the eggs in her body until they hatch ( ovoviviparity ), during which time the embryos feed solely on the egg yolk.
• Ovoviviparity, is a mode of reproduction in animals in which embryos develop inside eggs that are retained within the mother's body until they are ready to hatch.
• This would indicate the large and bulky Diadectomorphs laid spawning with aquatic tadpoles, internal fertilization with or without ovoviviparity, aquatic eggs with direct development or some combination of these.
• In ovoviviparity one or more egg hatches internally in the female, but they are not nourished after hatching and are immediately'larviposited'and continue their development outside the female.
• Traditionally this variety was classified into three modes, oviparity ( embryos in eggs ), viviparity ( young born live ), and ovoviviparity ( intermediate between the first two ).
• Two genera of labrisomid are noted for their ovoviviparity; " Xenomedea " and " Starksia " both retain eggs within their oviducts, where they develop in safety.
• The eggs are laid containing mature first instars, the female having incubated the eggs within her reproductive system until ready to hatch, a mode of reproduction known as ovolarviparity, more generally known as ovoviviparity.
• They agreed, however, that these eggs must have developed inside the mother which would later have given live birth ( a reproductive method sometimes called ovoviviparity ), but were likely expelled from the body when the mother died.
• Adenotrophic viviparity differs from ovoviviparity in that the eggs ( usually one at a time ) are retained within the female's body, hatch and are nourished through " milk glands " until the developed larvae are ready to pupate.
• Thorson's rule states that benthic marine invertebrates at low latitudes tend to produce large numbers of eggs developing to pelagic ( often planktotrophic [ plankton-feeding ] ) and widely dispersing larvae, whereas at high latitudes such organisms tend to produce fewer and larger lecithotrophic ( yolk-feeding ) eggs and larger offspring, often by viviparity or ovoviviparity, which are often brooded.
