The prize for having the tiniest heart in the world
The fairyfly, despite its name, is not a fly. It is a tiny insect about the thickness of a piece of paper; to view it, you will need a microscope. It's a wasp, not a fairyfly. If you ever get the chance to examine one under a microscope, you'll notice that the similarity extends to the Animal Kingdom's larger but no less remarkable heart. Zebra fish are known for their unique capacity to regenerate their hearts. Although their hearts are just approximately 04 Ines in diameter, if a zebra fish's heart is ever damaged or has an issue, it can typically heal itself. The zebra fish's heart is superior to that of humans, despite the latter's constant efforts to replace lost cells and repair damaged heart tissue. Let's examine cockroaches now. Our hearts consist of four chambers, each of which has a specific role. The system cannot function without all four chambers functioning as intended. Because they are powered by separate muscles, the 12 to 13 chambers that make up a cockroach's heart are arranged in a row along its average length of 1.5 inches. Because they function independently, the cockroach may not even be aware of the damage to any of the chambers, and most of the time, cockroaches survive without all of their heart chambers functioning properly. The heart of a hummingbird can beat up to 1200 times per minute, while the heart of a human athlete can only beat up to 220 beats per minute. This means that a hummingbird's heart is quite large in relation to its full size, making up roughly 2.5% of its total body weight. The blue-throated hummingbird flaps its wings up to 15 times per second; this movement is so fast that it cannot be perceived by the human eye. This impressive speed is backed up by an even faster heart, which beats up to 21 times per second. The emperor penguin is not just a species of penguins with a crown on their head, despite common misconceptions. Instead, these birds are fascinating swimmers that can dive up to 700 feet below the surface. Emperor penguins have extremely slow hearts, and when submerged in water, they can lower their heart rate to approximately 15 beads per minute. This reduces blood flow to all but the most essential organs and lowers their oxygen consumption, enabling them to use only the oxygen required for deepwater hunting. Across the animal kingdom, heart size is often quite proportionate. Approximately 6% of an animal's body weight is made up of these organs; dogs and wolves have larger Hearts, in contrast, make up about 8% of an animal's total weight; the heart of an average dog weighs about 20 ounces. If a human heart were to suddenly become enlarged with fat, it would be problematic very quickly, but that is not the case for pythons, which can weigh up to 250 pounds. Most of these increases are the result of the snake's heart swelling up due to fatty acids absorbed from the meal; these reptiles have adapted to do this in order to speed up their digestion, even though it still takes them days to process a single meal. Their blood becomes so full of fatty acids that it even changes color. completing our spectrum graphic at the opposite end The blue whale has the largest heart in the animal kingdom, and for good reason—these creatures are among the largest ever recorded. Their enormous heart is roughly the size of a bathtub and weighs more than the typical gorilla. Despite their size, animal hearts are remarkable to us humans. Most animals only have one heart, but some animals—like squids and octopuses—have three hearts—because that is how their system functions. To ensure they have enough oxygen in their bodies, two of their hearts pump blood to the gills; the third heart circulates blood throughout the body. Even if certain animals—like jellyfish, starfish, or corals—don't have hearts at all, it doesn't always indicate that they're cruel. Here are some incredible facts about the human heart—you don't need to Google it or consult an anatomy book to find out how big your heart is—to illustrate the point. Take starfish, for instance. They don't even have blood, which is likely why they don't require a heart. Simply squeeze your fingers to form a fist that is roughly the size of the heart. The heart is an incredible organ that keeps everything in our body active; it can beat roughly 105,000 times every day.
