At least eight different developmental patterns occur and include (1) ophiopluteus larvae, (2) reduced ophiopluteus larvae, (3) vitellaria larvae, (4) reduced vitellaria larvae, (5) abbreviated or direct developing internally brooded larvae (viviparous or ovoviviparous
), (6) abbreviated or direct developing externally brooded larvae, (7) abbreviated or direct developing larvae that develop within a capsule, and (8) planktotrophic-like larvae that are brooded.
Phenacoccus solenopsis is reported to exhibit an ovoviviparous
mode of reproduction with a very short egg incubation period ranging from a few minutes to a maximum of 2 h (Nikam et al., 2010; Vennila et al., 2010; Asifa et al., 2012; Prasad et al., 2012).
Vulva subterminal, uterus filling most of body cavity, with ovary convoluted in anterior region, ovoviviparous
The guppy, Poecilia reticulata Peters, 1859 is an ovoviviparous
freshwater fish of low waters native to the Caribbean Islands, Venezuela, Guyana, and northern Brazil (Amapa and Para States) (Reis et al., 2013).
Seasonal ovarian histology of the ovoviviparous
iguanid lizard Sceloporus jarrovi Cope.
Previously, dicephaly had been observed in shark species that are either viviparous (give birth to live young, like mammals) or ovoviviparous
(where the eggs develop and hatch inside the mother).
The Indian sand boa (Eryx johnii) also referred to as red sand boa or brown sand boa, is a non- venomous snake species which is ovoviviparous
, i.e., the young hatch live after a gestation period of 4 months inside the female's body.
Sexual dimorphism expressed in body size is common among viviparous and ovoviviparous
shark species (Sims 2003).
superbus) are well adapted to cool and temperate climates, and all species employ an ovoviviparous
reproductive strategy (i.e.
In this context, it should be mentioned that, of these three snake species, only the grass snake is oviparous; the other two species are ovoviviparous
. The chance of finding zoo-archaeological remains of oviparous species is higher since eggs or egg remnants can also be retrieved from archaeological digs.
This species has separate sexes (Figures 3(b) and 3(c)) and is ovoviviparous
with a planktotrophic larval stage .
The largespring gambusia, Gambusia geiseri, is an ovoviviparous
fish (Family Poeciliidae) thought to be endemic to the headwaters of the San Marcos and Comal rivers (Hubbs, 1957) although, recent genetic data suggest the San Marcos River as the likely origin (R.
