There is only one species of mammal that lays eggs, and that is the platypus.
-
There are only two types of mammals that lay eggs, the platypus and the echidna.
1. The platypus usually likes to burrow by the water, and its eyes, ears, and nose are closed when it is in the water. They eat a lot of food and consume the same amount of food as their body weight each day. Platypus is a carnivore, preying on insects and some other small animals that live on the bottom of flowing creeks and rivers.
Underwater, the platypus closes its eyes and uses its soft, sensitive mouth to fumble in the mud in search of food.
2. Echidna is one of the most primitive mammals, a general term for echidnas, which resembles a hedgehog in appearance, the tail is very short, the body hair becomes a hard thorn, there are fine hairs between the spines and the ventral surface, the snout tip is short and straight, the tongue is slender like a line, toothless, there is mucus, and it can stick out of the mouth to catch food. Echidna is also known as a spiny anteater, with both hairs and spines on its body, a long beak, feeds on termites, etc., and is good at digging. Although the echidna is an oviparous mononore, it also has a nursery pouch, in which the eggs are laid directly and incubated, and the young continue to live in the pouch for a period of time after hatching.
Oviparous mammals are ancient species that are a special case left over from the transition period when oviparous animals evolved into viviparous animals. Although not viviparous, these animals are still mammals because of their innate mammalian behavior, and their body coat has the characteristics of a series of viviparous animals of the traveling finch on their bodies. There are two species of empty bridges, both of which live in Australia.
They are Echidna and platypus.

Question 1: Which animals can lay eggs? The eggs are much smaller, she can excrete thousands of caviar at once Insects will also lay eggs, their eggs are very small, called eggs, and the eggs hatch larvae, and then become pupa, adults... For example, silkworm babies. Snails also lay eggs, it is a genus.
In mollusks, their eggs, also called eggs, are round and shiny, and they lay their eggs in moist holes, covering them with a layer of yolk and egg whites.
In addition to birds, there are many reptiles that also lay eggs, belonging to the order of reptiles and turtles. In addition to the inch-liquid snake and turtle, such as: Chinese alligator, monitor lizard, crocodile lizard, python (all are national first-class protected animals), giant salamander, giant gecko (all are national second-class protected animals) and so on.
There are also mammals, platypus, and hedgehogs.
Probably the most precious of the eggs are the dinosaur eggs (fossils).
Chickens and eggs, quail and quail eggs.
Snake and snake egg, next to the egg for contrast.
Turtles and turtle eggs, snails, spawning fish and roe.
Shanshan also asked her mother if the penguins also lay eggs? Mom didn't know either. After checking it, I found that all birds lay eggs.

Perhaps the most precious of the eggs is the dinosaur egg (Fossil Mausoleum cherry tree).
Chickens and eggs, quail and quail eggs.
Snakes and snake eggs, next to which are eggs to make a song of contrast.
Turtles and turtle eggs, snails, spawning fish and roe.

Most body coats; constant body temperature; viviparity (with the exception of monopore) and lactation; The left and right chambers of the heart are finished.
Mammals (including fossils and living species) can be divided into protozoan subclasses, posterior subclasses, and euzozon subclasses. The protozoan subclass includes extinct Mesozoic mammals and the present monoforare. There are echidna and platypus in the order Monoceda, which are native to Australia, Tasmania and New Guinea, and there are only 3 species of 1 order, 2 families, 3 genera and 3 species.
In addition to the protozoan subclass and the eumatric subclass, there are also posterior mammal subclasses, including various marsupials, which are found in South and North America, Australia and their adjacent islands, with a total of about 250 species in 86 genera and 7 orders, 19 families; The subclass eumatria, including a variety of placental species, is widely distributed throughout the world.
-
Animals with hair on their bodies are breastfed with milk secreted by their mammary glands.
-
Mammals are also divided into viviparous and oviparous, such as monoforre animals are oviparous.
-
It is the lowest mammal, due to the genital pore and excretory chole, which is connected to the outside of the body by a common pore. So some mammals lay eggs.
-
All mammals, except for Monoforare, are viviparous. Monoforarees are oviparous. It is the lowest mammal.
-
Mammals are found all over the world, both on land and underground.
-
This is because their reproductive structure is relatively special.
-
Not all mammals are viviparous.
-
It's because they're special.
-
Because some mammals are oviparous.
-
This is because mammals are different.
-
Platypus, I guess it's this.
-
Platypus, it has to be this.
