Are Osteichthyes oviparous or viviparous?
Fertilization is usually external, but can be internal. Development is usually oviparous (egg-laying) but can be ovoviviparous, or viviparous.
Are fishes oviparous?
Overview. Most fish are oviparous, although ovoviparity and viviparity are also well represented. Parental care may occur in oviparous fishes but is quite variable, with many fishes scattering eggs and displaying no care whatsoever for offspring.
What Chondrichthyes are oviparous?
Reproduction in chondrichthyan fishes is divided into two main modes, oviparity (egg laying) and viviparity (live bearing). Oviparity is restricted to the orders Carcharhiniformes (ground sharks), Heterodontiformes (bullhead sharks), Orectolobiformes (carpet sharks), Rajiformes (skates) and Chimaeriformes (chimaeras).
Which fish is oviparous fish?
The female usually lays the eggs, and the embryos in the eggs develop and hatch outside her body. These kind of fish are called ‘oviparous’ fish. Oviparous fish develop by obtaining food from the yolk in the egg. Salmon, for example, are oviparous.
How many fish are oviparous?
The most common reproductive strategy in marine ecosystems is oviparity. Approximately 90% of bony and 43% of cartilaginous fish are oviparous (See Types of Fish).
Which sharks are oviparous?
Oviparous sharks include horn sharks and swell sharks (Cephaloscyllium ventriosum). Port Jackson sharks carry their egg cases in their mouths, possibly to drop them in a hiding spot. This is about the only shark parental care observed by humans.
What are ovoviviparous sharks?
Ovoviviparous sharks are similar to viviparous species in that there is internal fertilization and the young are born live, but differ in that there is no placental connection and the unborn young are nourished by egg yolk. However, the mother’s body does provide gas exchange (respiration).
Is rohu a bony fish?
Examples of bony fishes (Osteichthyes) are salmon, flying fish, sea horse, rohu, trout.
Is Dogfish a bony fish?
Cartilaginous fishes are jawed fish with paired fins, paired nares, scales, a heart with its chambers in series, and skeletons made of cartilage rather than bone. Shark fish are called dogfish because they travel and hunt in packs. Shark is a cartilaginous fish.
Is Shark a bony fish?
Unlike fishes with bony skeletons, a shark’s skeleton is made out of cartilage. This is a flexible but strong connective tissue that’s also found throughout the human body, in places like the nose, ears, and in joints between bones.
Is Koi a bony fish?
Osteichthyes, or bony fishes, include the remaining fish-like species who have skeletons composed largely of bones (meaning they are hard and calcified). There are thousands of examples of Osteichthyes seen in nature including goldfish, trout, koi, catfish, salmon, piranhas, tuna, swordfish, and many, many more.

Is Whale oviparous or viviparous?
viviparous
Mammals are viviparous as they give birth to living young ones with a few exceptions. The whale is an aquatic mammal whereas, bats are flying mammals. Both give birth to young ones & hence, are viviparous. Birds of all types lay eggs, i.e. they are oviparous.
Are Tiger Sharks oviparous?
The tiger shark is the only species in its family that is ovoviviparous; its eggs hatch internally and the young are born live when fully developed.
Are Dolphins oviparous?
Examples of marine life that are viviparous include: Marine mammals such as whales and dolphins, pinnipeds, sirenians, and sea otters. Some sharks, including blue sharks, white sharks hammerhead sharks, and bull sharks, and. Some other fish species, (e.g., the Pacific ocean perch).
What is an oviparous animal?
An oviparous animal is one that produces eggs, and the young hatch after being expelled from the body. While fertilization of the egg can occur internally or externally, oviparous animals always hatch their young outside of their body. Many amphibians, birds, fish and reptiles are oviparous and often make nests to protect their eggs.
What type of eggs do bony fish have?
Oviparous bony fishes release eggs, and the developing embryo is nourished by a yolk sac. The eggs of a bony fish generally are spherical. A soft membrane protects the egg.
What is an example of an ovoviviparous fish?
Examples of ovoviviparous fishes are the seahorses (family Syngnathidae). In contrast to most other animals, it’s the male seahorse that incubates fertilized eggs. The female seahorse deposits eggs into a pouch on the male’s abdomen. The male releases sperm into the pouch, fertilizing the eggs.
What is a viviparous fish?
Viviparous fish produce fish internally. Males fertilize the eggs that are carried inside of the female. In the case of viviparous species the young, otherwise known as fry, are born completely formed. This type of production results in an increase of offspring survival. Most sharks belong to this group of viviparous fish.
