What other animals besides birds are oviparous

Except for mammals, the rest of the animals are basically oviparous, such as birds, snakes, crocandiles, turtles, lizards, frogs, salamanders, fish, insects, ......Among the mammals, platypus and echidna also lay eggs.

Reptiles, fish, and other mammals are also oviparous.

Animals that reproduce by laying eggs are called "oviparous". Birds, reptiles, and most fish and insects are almost oviparous. For example, chickens, ducks, fish, frogs, turtles, butterflies, etc. are all oviparous animals.

After laying eggs (eggs), oviparous animals hatch and become animals, and their nutrition comes from the eggs themselves.

Reptiles are all, mammals have platypus, echidna.

Fish, snakes, amphibians, insects and much more.

Reptiles, amphibians, fish, insects.

Reptiles, amphibians, fish.

First of all, among the vertebrates, except for the animals under the subclass Mammalian Beasts, which are viviparous, all the others are oviparous, including bony fish, cartilaginous fish, amphibians, reptiles, birds, and some more primitive jawless generals.

Secondly, invertebrates, generally speaking, except for animals such as hydra can reproduce through teething, sponges, planarians, and anemones can reproduce through broken reproduction, and other animals can only reproduce through sexual reproduction, they are all oviparous. Common ones include arthropods (insects, crabs), mollusks (slugs, also known as slugs), annelids (leeches), and various parasites.

Reptiles, fish, and a large number of invertebrates, the class of insects are mostly oviparous.

Nematode animals (such as roundworms) are also the same.

However, the eggs of reptiles and birds are amniotic eggs, which are fundamentally different from those of other animals.

The subclass of mammals is also an amniotic egg.

Most animals are viviparous or oviparous, but there are also some special animals, such as seahorses, which hatch fertilized eggs in their mouths and then put them in a nursery bag on the belly of male seahorses, which is actually a kind of oviparous.

Parthenogenesis: Present in arthropods and some reptiles and fish, it refers to the mode of reproduction in which an egg develops into an individual without fertilization. It can be divided into occasional parthenogenesis, frequent parthenogenesis, and periodic parthenogenesis.

1.Animals that are trapped in eggs are: chickens, ducks, fish, frogs, turtles, butterflies, ostriches, snakes, birds, lizards, geese, penguins, crocodiles, etc.

2.Common viviparous animals: cats, dogs, monkeys, lions, tigers, pigs, mice, whales, cows, sheep, horses, rabbits, foxes, bears, etc.

3.Oviparous Definition: The process by which an animal's fertilized egg develops independently outside the mother's body is called oviparous.

Oviparous animals are animals that reproduce by laying eggs. Birds, reptiles, most fish, and insects in general are almost oviparous. For example, chickens, ducks, fish, frogs, turtles, butterflies, etc., are all animals that lay eggs.

After laying eggs, oviparous animals become animals after hatching, and their nutrition comes from the eggs themselves.

1. We can classify the eggs of animals according to their external morphological characteristics.

2. The shape of the egg is spherical or elliptical. An egg is a single female reproductive cell that has matured. The size of eggs varies greatly from animal to animal, and some can be observed with the naked eye, such as fish eggs and frog eggs; Some eggs can only be seen with the help of a microscope, such as the eggs of parasites.

The one who watched the tea took the tea and ate it. Guo Shuban said: "Mrs. Jin has always been in the house, when did you come to Jiangnan?"

Although it was 'really fake', he also lost a few taels of silver. I was bored at home, because Mr. Yun Si Xun was an old friend of Beijing, so I came to Yangzhou to see him, and I recommended him on the box and sent a few hundred taels of silver.

1.Antelope. 2.Platypus.

Correct answer to the case of Tan Feng: platypus.

The platypus is a mammal, and although the mother also secretes milk to feed the young, it is not viviparous but oviparous. That is, the eggs are laid by the mother, and they are hatched by the temperature of the mother like a bird.
