Why don t frogs that eat bugs for a living eat dead bugs?

When we were in school, our textbooks told us that frogs had bad eyesight and had to eat activity bait. However, our farm has raised frogs that do not eat insects on nearly 50 acres of land. Come and see what he eats.

<> it turns out that we have completely changed the eating habits of frogs, and the frogs that used to eat animal bait were relatively productive, which is also the reason why frogs remain high. For example, we used to have farmers raising frogs, and if the area is a little larger, they will worry about bait, and today they want to eat hundreds of catties of bait**? Breeding a day can not produce such a high yield, followed by animal bait fly maggots, earthworms are mainly bred in the manure, the bacterial content is very high, after the frog is eaten, enteritis and other diseases are high, but also can not reach high yield, and even some farmers are bankrupt, looking at the barren site, it is really a sad tear.

Now after years of exploration, we have completely changed the frog's eating habits, so that it uses glasses to blur feeding, has become the current olfactory feeding, frogs can eat feed from tadpoles all the time, the cost of manual operation is also low, there is no need to breed animal bait, directly buy frog special materials, it is also cleaner, frogs will have less disease, which can greatly improve the yield of frogs.

I know that some people will say that feed breeding is not good, in fact, how to say it, we have a certain misunderstanding of feed, feed is also a lot of food prepared, but the nutrition will be more comprehensive, just like the milk powder that children eat now, it is true that some bad businesses will produce some unqualified milk powder, but most of the milk powder is good, and now most of the children are eating milk powder, we can not choke on food.

At the same time, the frog that eats feed can also protect the frog to a greater extent, a species that is about to be extinct by pesticides and fertilizers, and now because of the breeding frogs, the traders can receive a lot of frogs at a time, and there will be fewer and fewer wild frogs outside without a market.

Probably because frogs themselves only see moving objects, they don't eat dead bugs.

Because dead bugs don't have any heat on their bodies at all, they can't tell the difference.

Because the eyes of frogs can't see anything still clearly. So in fact, frogs eat insects that can move.

Frogs feed on insects, but also on snails, snails, shrimps, and fish. The vast majority of the insects eaten are agricultural pests. It has been estimated that a single frog can prey on 70 insects a day and eliminate 15,000 pests a year.

Therefore, the frog is an animal that is beneficial to agriculture and should be promoted for protection. In late autumn, when the weather gets colder, frogs hibernate under the water or in burrows, and return to the water to breed when the weather warms up the following spring.

01 The eyes of frogs are compound eyes, which are different from human eyes, which are composed of many small eyes, and are characterized by only reacting to moving objects and being indifferent to stationary objects. So it's not that the frog doesn't eat, it's that it can't see.

Frogs' eyeballs do not regulate themselves, they are only sensitive to things that are moving, and it is difficult to detect things that do not move, flies do not fly frogs do not perceive, they do not eat but cannot eat.

Because the eyes of a frog are unable to see (or cannot see clearly) stationary things, the eyes of a frog are different from the eyes of ordinary animals, they are specialized in looking at moving objects. The moth and the fly do not react to the frog's eyes, but as soon as the moth moves, the frog will immediately spot it and jump up to prey on it according to its flight direction and speed. It's no wonder that some zoologists joke that frogs like to eat flies, but that frogs can starve to death if they sit in a pile of dead flies.

The frog's eyes also have a special ability to recognize different images. It can instantly identify its favorite flies among the various shapes of flying critters, while the background of the flying critters is not responsive to the frog's eyes. In other words, the frog's eye is not like a camera, it can take pictures of everything in front of the lens without missing anything, and it only sees the things that are useful to it.

Frogeye can quickly spot moving targets, quickly determine the target's position, direction of movement and speed, and immediately select the best attack posture and attack time.

Frogs belong to the amphibians of the phylum Chordates, amphibians, tailless, frogs, adults without tails, eggs laid in water, fertilization in vitro, hatching into tadpoles, respiration with gills, after mutation, adults mainly use lungs to breathe, and also use ** breathing. The vast majority of frogs reproduce through in vitro fertilization, and the fertilized eggs hatch into tadpoles outside the mother's body. Globally, only 10 to 12 species of frogs have evolved to fertilize in vivo, and some of them will release fertilized eggs from their bodies to hatch into tadpoles.

Frogs are slimmer and are more good swimmers. The neck is inconspicuous and has no ribs. The ulna of the forelimbs heals with the radius, and the tibia of the hind limbs heals with the fibula, so the claws cannot rotate flexibly, but the limbs are muscular.
