CATDOLL : CATDOLL: How platypuses reproduce

1. How does the platypus reproduce?

The platypus is an oviparous mammal.

2. How does the platypus reproduce?

Oviparous, hatching takes a while, and the platypus babies feed on milk after hatching.

It is called a living fossil because it is both oviparous and a mammal, and is generally considered to be an intermediate species in the evolution from reptiles to mammals.

3. How do kissing fish reproduce?

The female fish is wider than the male fish, has a smaller anal fin, and its abdomen is noticeably swollen during the fertilization period.

Kissing fish are oviparous fish. Although they do not spit bubbles to build nests, their eggs are floating. Parent fish have the habit of swallowing eggs, so more floating water plants should be planted in the breeding tank to facilitate the attachment of eggs. Kissing fish enter sexual maturity in May and can reproduce many times a year.

It is not difficult to breed kissing fish. Because kissing fish are large, the breeding tank should not be too small. The water for breeding requires a hardness of 6-9, a pH of 6.5-7.5, and a suitable water temperature of 27 degrees Celsius. Parents can be placed in the breeding tank at a ratio of 1:1, and some distilled water can be added to the breeding tank to stimulate the estrus of the parent fish. After a chase, the parent fish begin to ovulate and fertilize. The volume and mass of kissing fish eggs are less than the volume and mass of water, so they will float on the water surface, and the spawning process will last for several hours. Each female fish can lay more than 1,000 eggs, and some can reach 2,000-3,000 eggs. Kissing fish do not have the habit of protecting eggs. After laying eggs, the parent fish should be removed in time and raised separately to prevent them from eating them. Kissing fish is also known as kissing fish, kissing fish, kissing fish, kissing fighting fish, fragrant kissing fish, peach blossom fish, and climbing perch family. It is native to Java Island and Borneo in Indonesia, Southeast Asia. In nature, kissing fish can reach 30-40 cm in length, while those raised in aquariums are generally only 15-20 cm long, making it one of the larger species in the family Percichthyidae.

4. How to breed soft-shelled turtles

The Chinese soft-shelled turtle, scientifically known as the Chinese soft-shelled turtle, is an amphibious reptile that has strong adaptability and resistance to adverse environments and diseases and is a long-lived animal in the animal kingdom. The soft-shelled turtle has a clever protective color. It is difficult to be discovered by hostile animals. The soft-shelled turtle is an omnivorous animal that eats both plants and animals. The soft-shelled turtle is an oviparous animal and lays eggs mostly between mid-April and October. A soft-shelled turtle can lay eggs 3 to 4 times a year, and after 50 days, the small soft-shelled turtle will hatch and be born. The soft-shelled turtle is a cold-blooded animal, and its activities change with temperature changes. In the spring, when the water gradually rises to above 20℃, it begins to estrus and mate. In an environment of 25-30℃, the soft-shelled turtle has a strong feeding ability and grows very fast, which is the best season for artificial breeding. In artificial breeding experiments, soft-shelled turtles have three fears: first, they like quietness and are afraid of being startled; second, they like the sun and are afraid of wind; third, they like cleanliness and are afraid of dirt. They like to live in a quiet, clean, sunny environment.

The method of making a homemade incubator with artificial humidity control is both simple and easy, and can achieve a relatively ideal hatching rate.
