What kind of animal really has the most powerful heart?

Personally, I think that there are two animals with the most powerful hearts in the world, the first is the blue whale with the largest heart, and the second is work efficiency.

The tallest cheetah. Especially the cheetah, its endurance is really strong, because at this high speed, the average animal only needs tens of seconds to make the heat in the body unable to release and have a negative impact, while the cheetah can last about 3 minutes even at the highest speed.

On Earth today, the animal with the strongest heart is, of course, the blue whale, and the strongest heart is also the largest heart. We know that the blue whale is the largest animal living on Earth today, with a body length of up to 30 meters and a weight of more than 150 tons, so how big is the heart of the blue whale? Although we have a lot of records about the size of the blue whale, the size of its heart is speculated.

In 2014, several blue whales stranded on a beach in Newfoundland, Canada, and they eventually died. These dead blue whales gave us the opportunity to explore the dimensions of the blue whale's heart, and biologists dissected one of the blue whales, 23 meters long, and removed a huge heart from its body that was meters high and wide.

Rumor has it that the heart of the blue whale is the largest in the world, his heart is about the size of a small car, and scientists have studied that their heart weighs 180 kilograms, but because they are very rare, their hearts have not been studied in detail.

The blue whale is arguably the most powerful animal in the heart, the blood will drive nutrients and circulation to cause metabolism, and the more blood it provides, the stronger the heart.

Animals with three hearts are horseshoe crabs, octopuses, and cuttlefish.

Three-hearted animals are very rare in nature, this structure is very peculiar, and the animals with three hearts are now known to be horseshoe crabs, octopuses and cuttlefish.

LAL:

Horseshoe crabs have three hearts and contain a lot of copper ions in their blood.

So it's blue. The horseshoe crab has three hearts, and it has a strong circulatory system.

Carbon dioxide in the horseshoe crab's blood when the gill heart receives venous blood from the periphery and transports it to the gills.

It will be replaced by oxygen. The blue color that people see is the color of vanadium in the horseshoe crab's blood.

Octopus:

Octopuses are called "alien creatures" because of their special body structure. Each octopus has three hearts, one of which contributes to the circulation of blood throughout the body, and the other two smaller hearts supply blood to the gills. The octopus has three hearts that provide more oxygen and energy to the brain and limbs.

Cuttlefish:

Cuttlefish have three hearts, two of which are in the gills and the other one that supplies blood to the rest of the body. Moreover, the blood supplied by the heart of the cuttlefish is not red like us, but blue, because there is no hemoglobin in their blood.

In its place is the copper protein.

Scallop animals do not have hearts. Protozoa are single-celled organisms and do not have hearts. For example, scallops do not have a heart before the phylum Chordates, and only after cephalic chordates do animals develop hearts such as fish, amphibians, etc.

Octopuses have three hearts, two memory systems, and 500 million neurons in their brains. In addition to octopuses, there are many earthly creatures with multiple hearts, such as earthworms.

The heart of an earthworm is not the same as the heart of a higher animal, it is actually a bulged annular blood vessel.

Animals without hearts.

Animals don't have hearts, such as roundworms.

Hookworms abalone, jade snails, fragrant snails, red snails, Dongfeng snails, mud snails, cockles, mussels.

Scallops, clams, oysters, clams, clams, clams, clams, squid, squid, octopus, snails, snails, mussels, clams If the animal you are talking about is a mammal.

are all protozoa phylum.

Animals with two hearts survive as earthworms. Earthworms are rich in nutrition, rapid reproduction, miscellaneous diets, and high yield in artificial breeding. Good economic benefits.

Earthworms can be used as a valuable medicine** for many diseases, and can also be used as high-protein food and feed.

Earthworms dig holes to loosen the soil, decompose organic matter, create good conditions for the growth and reproduction of soil microorganisms, and play a special role in soil improvement, eliminating public pollution, protecting the ecological environment, in material cycle, biodiversity, etc.

Earthworm living habits

1. Likes moisture and is afraid of immersion.

Earthworms prefer to live in a humid environment and should not be too dry, but they should not be too wet to soak (except for water earthworms). The humidity of the substrate here includes two aspects, one is the humidity of the base soil, the other is the humidity of the air humidity, the humidity of the general breeding base soil is required to be 40%-60%, (it is good to hold the fingers of the base soil to see the water and not to flow down), and the relative humidity of the air is adjusted to 60%-80% as well.

2. Temperature-loving, cold-phobic, heat-cold.

Earthworms like to live in warm environments, and they are afraid of both cold and heat. In 0 -5 dormant, 32 or more stop growing, 40 or more death, the suitable temperature is 15 -30, the best temperature is 20 -25, we want to obtain good breeding benefits, it is necessary to maintain the best temperature of 20 -25 breeding environment all year round.

Earthworms prefer to live in a quiet environment and are most afraid of vibrations. Farms should be located in quiet places. Do not shake or frequently turn the base soil up and down. Frequent vibration will adversely affect the growth and reproduction of earthworms.

4. Acid-loving and salt-phobic.

Earthworms prefer to live in acidic or neutral soils, or in environments with water sources, and are most afraid of approaching saline, alkaline soils, or saline water sources. If you encounter saline soil or water sources, adjust the pH. The alkali should be adjusted with ammonium dihydrogen phosphate, and it can also be adjusted with 2% carcoal water, otherwise the earthworm can not survive.

5. Likes sweet and is afraid of spicy.

Earthworms like to eat sweet, sour, and fishy food, such as watermelon rinds, rotten fruits, rotten tomatoes, and fish washing water. Most afraid of eating spicy food, such as garlic, green onions, peppers, etc., with the city's domestic garbage to feed earthworms should pick out the spicy food and then feed.
