Viviparous fish are fish that give birth to live young, the eggs develop whilst receiving nutrition from the parent. See also: Category:Ovoviviparous fish - fish which give birth to live young which do not receive nourishment from the parent whilst in the womb.
Zenarchopteridae, the viviparous halfbeaks, is a family of ray-finned fishes in the order Beloniformes. The Zenarchopteridae exhibit strong sexual dimorphism , practicing internal fertilisation , and in some cases ovoviviparous or viviparous (the family also includes oviparous species).
The viviparous eelpout feeds on bottom-dwelling invertebrates, such as crustaceans, and fish eggs and fry. [6] Adults mate during the months of August and September using internal fertilisation. The fish are notably viviparous, giving birth to 30–400 live developed young. Unusually, it does so during winter when water temperatures are ...
Gambusia is a large genus of viviparous fish in the family Poeciliidae (order Cyprinodontiformes). Gambusia contains over 40 species, most of which are principally found in freshwater habitats, though some species may also be found in brackish or saltwater habitats.
Deep-sea chimaera photographed by the NOAAS Okeanos Explorer.Visible on its snout are tiny pores which lead to electroreceptor cells.. Chimaeras are soft-bodied, shark-like fish with bulky heads and long, tapered tails; measured from the tail, they can grow up to 150 cm (4.9 ft) in length.
This is common in molluscs, arthropods and fishes, and is found in most frogs. [1] Oviparity: fertilisation is internal, but the female lays zygotes as eggs with a substantial quantity of yolk to feed the embryo while it remains in the egg. The egg is not retained in the body, or only for a limited time. [1] Oviparity is found in insects, birds.
Because the newborn fish are large compared to the fry of oviparous fish, which are those that lay eggs, newborn fish of livebearers are easier to feed than the fry of egg-laying species, such as characins and cichlids. This makes them much easier to raise, and for this reason, aquarists often recommend them for beginning fish breeder hobbyists.
The viviparous brotulas form a family, the Bythitidae, of ophidiiform fishes. They are known as viviparous brotulas as they generally bear live young , [ 1 ] although there are indications that some species (at least Didymothallus criniceps ) do not. [ 2 ]
