In the breeding season of frogs, the amount of eggs laid by frogs is also very large, and a female frog can lay thousands of eggs at a time, so if the frog eggs are successfully hatched, flocks of small tadpoles can be seen in the pond and river waters. Recently, in the United States, a man recorded the process of finding frog eggs, hatching small tadpoles, and growing into frogs, and flocks of small frogs jumping around, making biological experts worry that these frogs will eat insects in large quantities, becoming a locust version of the ecological crisis.
According to reports, these clumps of frog eggs are found in a dry pond, if there is no water to enter, or no one to rescue, these frog eggs are easily dried, there is no chance to become frogs, in order to save these, the man loaded N buckets of frog eggs back.
The man collected millions of frog eggs and created several simple ponds for them, which soon turned into hundreds of thousands of frogs, which was sad because the little frogs jumped around, the whole back garden was black and hempy, and the frogs also broke into the neighbor's house and became small animals that disturbed the people.
These practices have attracted the criticism of a biologist Cooles, hatching hundreds of thousands of frogs, when they are growing, how many insects need to be preyed, when these small frogs escape to the wild, a large number of species of insects are swallowed, some tend to locust behavior, that requires insects to spread pollination plants, will be affected, including forestry, crops, etc. will also reduce production, so it is not advisable to collect and hatch so many frogs.
If in the wild, although the number of frog eggs and tadpoles is also very large, they have many predators, all kinds of fish will swallow a large number of frog eggs, etc., after becoming frogs, they will also be preyed on by snakes, birds, etc., so it is impossible to appear hundreds of thousands of frogs at a time, making it difficult for natural enemies to control the effective number.
- The difference between a frog egg and a toad egg
Among frogs, there are about 4800 kinds of known frogs, there are about 300 kinds of toads, toads are also a kind of frog, all toads are frogs, frogs are not necessarily toads, frog skin is relatively smooth, and toads generally have many knots on the body surface, toads are not as good as frogs, but frog eggs and toad eggs are very similar.
Frog eggs are also a little different from toad eggs: if the egg formed by the egg is a clump, this is the frog's egg; If many eggs form a continuous, linear band, and the eggs inside the band are laid in two rows, like a string of beads, this is the egg of the toad.
- Different frogs have different breeding methods
Most frogs lay eggs on aquatic weeds, frog eggs slowly become tadpoles, tadpoles are black, rounded bodies, have a long tail, tadpoles grow day by day, first grow hind legs, and then grow front legs, tails gradually shorten and degenerate, and finally become frogs, but these kinds of frogs, there are different ways.
There are egg protection behavior - glass frogs, female frogs generally only need to lay eggs in the water, rarely egg protection behavior, let them survive on their own, and in South America glass frogs lay eggs on the leaves, frog eggs laid on the leaves if there is no water, can not hatch, so adult glass frogs to ensure that these eggs do not dry out, while protecting them from parasites and small predatory insects.
Most frogs need to go through the tadpole stage to become frogs, most frogs need to go through the tadpole stage to become frogs, distributed in Papua New Guinea, the female frogs only lay 1 to 2 eggs at a time, the number is very small, do not need to go through the tadpole stage, it is more convenient to take care of young frogs, this is because they live in the humid environment of the rainforest bottom, enough to maintain moisture, no longer need to be with the water.
The fastest hatching toad - Panamanian golden frog, many species of toad eggs the incubation period is generally 6-7 days, a week later hatched into tadpoles, Panamanian golden frog eggs hatched into tadpoles only 1 day, its reproductive growth rate is very fast, in the magical nature, there are many beautiful and dangerous and strange frogs!
Pay attention to the six dimensions of nature And let nature know nature!
