Most animals don t live as long as humans, so do you know which animals have a short lifespan?

The original intention of our pets is to hope that there is an animal that can live with us, and some pets may be far away from us for various reasons, causing us to be overly sad. In some people's requirements for choosing pets, they may want to choose a long-lived animal to accompany them, not seeking to be rich and expensive, but only want to see only their pets for a month to accompany them to old age, but this idea is also unrealistic. So let's find out today which animals are relatively short-lived, and we can avoid these small lifeforms.

A lot of little girls will like to put itRabbitsFeed it as a pet, but unfortunately a rabbit can live up to ten years old, so if you plan to adopt a rabbit, be sure to take good care of it. Guinea pigsThe name sounds like a long-lived animal, but its name is the opposite of its lifespan, guinea pigs generally only live for four years. Few people will knowMosquito-eating fishThis creature, and the lifespan of this creature cannot be shorter, they can only live in this world for two years, they are the animals that destroy mosquitoes, and they are also animals that live in the water.

Living in a fairy tale worldChameleon, the name may sound a bit historical, they can change the shape of their body, they can also change the color of their body, but they can't change their lifespan, they can only live for a year. RatsIt should be relatively unpopular in our lives, and we will all try to eliminate it, and its lifespan is the same as that of chameleons, only one year. It is often found in rice paddiesDragonflies, they have a forgiving color ** but can only let us enjoy the beauty for four months, but we will not remember which dragonfly we have seen.

AntsLike rats, they are not good animals for us, not only do ants bring some benefits to our lives, but they also affect our lives, and ants generally live for three weeks. Furry animalsAs the second-shortest-lived creatures, we may not have heard of them, they live in the ocean, and they leave this world three days after they are reproduced. The shortest-lived animal is oursMayfliesThe moment it descends on this world, it also means that it will leave this world, which is the shortest lifespan of any creature in our world.

1.Mayflies (a few hours). 2.Paramecium (one night). 3.Mosquitoes (5-12 days).

Plankton, paramecium, mosquitoes, these are very short-lived animals, and at the same time very old animals.

These include paramecium, mosquitoes, and worker bees, especially worker bees, which die after stabbing people.

Mayflies, an adult mayfly can only survive for one day.

I know that there is a substance whose lifespan is 10 to the minus 25th power! It's called Miuko! It is the shortest-lived substance ever discovered by man! Hehe.

The world's shortest-lived vertebrate: the goby, a reef fish that can live up to 59 days.

It's mayflies, they only have a few hours to live.

So they'll be on the water.

Rapid mating. Reproduction.

1. Mayflies have the shortest lifespan.

2. Mayflies, commonly known as mayflies, have ancient and special traits and are the most primitive winged insects. It can be divided into the same class as dragonflies, and their wings cannot be folded. Mayfly insects are slender and soft, usually 3-27mm in length, short antennae, developed compound eyes, large mid-chest, developed forewings, vestigial hindwings, a pair of very long tail whiskers at the end of the abdomen, some species also have **tail filaments, juvenile aquatic, adults to live in water for 1 to three years before adults, adults do not eat, adult life is very short, only one day, but it blooms the most brilliant brilliance in this short life.

3. Mayflies, commonly known as mayflies, have ancient and special traits and are the most primitive winged insects. The body is small or medium, elongated, and has soft body walls. The head is small, the antennae are short, and the bristles are hairy.

The compound eyes are well developed, and the compound eyes of females are often far from the left and right; Males often have large compound eyes, close to left and right, and each compound eye.

4. The upper and lower parts of the eye are often different, generally the upper half of the small eye surface is larger than the lower half, and there are also two parts that are completely separated. 3 in one eye. The mouthparts are chewing, because the adults do not eat, there is no ability to chew, the upper jaw degenerates and disappears, the lower jaw also degenerates, and there are often lower jaw mayflies.

The thorax is the largest in the mesothorax, and both sub-adults and adults are able to fly through the air. Adult worms have thin, shiny walls and are often white and yellowish. There are winged pairs of one or two pairs, and the frequency of vibration is very small when flying.

5. The anterior and hind thorax are small but not significant, the wings have two pairs, triangular, fragile, membranous, mostly large forewings, small hindwings, and there are also vestigial hindwings, which stand erect on the back of the body when resting. The wing veins and wing joints of mayfly are underdeveloped, and the wing veins are the most primitive, with many wing veins, many longitudinal veins and transverse veins, and they are reticulated. The surface of the wings is fan-shaped.

The foot is weak and is used only for clinging. Tarsal joints 1 to 5 segments, with 1 pair of claws at the end.

The shortest-lived animal is the mayfly. The shortest-lived animal in the world, with a lifespan of less than 24 hours from birth to death, is the mayfly, the most primitive winged insect. It can be divided into the same class as dragonflies, and their wings cannot be folded.

Mayflies usually only live for a few hours after hatching from their pupal shells, and they rarely live longer than a day.

Features of mayfliesMayfly insects are slender and soft, usually 3-27mm in length, short antennae, developed compound eyes, large mid-chest, developed forewings, vestigial hindwings, a pair of very long tail whiskers at the end of the abdomen, some species also have **tail filaments, juveniles are aquatic, adults do not feed, and the life span is very short, the shortest is only one day. Adult mayflies don't eat, and after molting, their digestive tract fills with air — before the last molt, the midgut heals to form a closed, sausage-like balloon.

It's filled with air, which allows the larvae to float to the surface of the water easily. Mayfly larvae live in a variety of freshwater habitats, most of which are found in living water at moderate temperatures and in constant flow, a few can survive in saltwater, and one even survives on land, and adult life is generally spent in flight. It is found all over the world, except in Antarctica, high Arctic latitudes and some oceanic islands.

Paramecium and amoeba are the shortest-lived animals.

Paramecium is a small, cylindrical protozoan that is made up of only one cell and is a unicellular animal that is hermaphroditic. The most common is Cercocerium paramecium. The body length is only 180 to 280 microns.

It and amoeba have the shortest lifespan, measured in hours, and the lifespan is about a day and night. (Paramecium can live for more than five days and nights.) ）

Because the faster the speed of the lifeline, the less affected by sunlight or gravity, (the essence of aging I have already discussed), so its life is long, but then again, the faster the movement of the lifeline, the straighter its trajectory, which in turn contributes to the shorter the lifespan, generally speaking, the faster the lifeline movement, the smaller the size of the life, in short, the size of the life is related to the curvature of rotation, but also related to the speed of rotation, and more related to the acquired nutrition is sufficient, The length of life is related to the curvature of the lifeline, the speed of the lifeline, and the size of the body. Females live longer than males and have smaller and curved bodies than males, and those with smaller bodies of the same sex have a longer lifespan, and those with more curved lifelines are younger, and it is difficult to compare between different classes, which is very complicated. The main thing that has a heart is the number of heartbeats, the maximum number of heartbeats in an animal's life is fixed, turtles are slow and have a slow heartbeat, so they live long, cats react fast, and have a fast heartbeat so they have a short lifespan.

Man is the only alternative.

The survival of animals is affected by various environmental factors, so that they generally cannot reach their natural lifespan, such as the natural lifespan of humans should be about 160-200 years old, but in fact, no one has reached this record; The normal lifespan of mammals is about 8 to 10 times that of their development, and is also related to their body shape, habits, and environment.
