Five of the toughest animals and plants in the world
Koi carp
Koi carp is a kind of ornamental domestic carp. Koi fish biologically belong to the family Cyprinidae, the largest family of all fish species, with over 1,400 species. It is a high-end ornamental fish that is popular around the world today. It is known as “living gem in water” and “swimming work of art”. Because it does not have high requirements for water quality, has diverse eating habits, and is easy to breed, it is popular among people. They are usually kept in pools with artificial rock gardens or decorative ponds. Surprisingly, some species live more than 200 years. The longest known lifespan was a koi named Hanako, who died at the age of 226.
Antarctic sponges
Perhaps due to extremely cold temperatureses of the Southern Ocean, this immobile creature has a rather slow growth rate. Some of the oldest individuals are estimated to be 1,550 years old. Although sponges are the simplest type of multicellular animal, they are a large family of more than 10,000 species. Sponges also have a relatively long lifespan, and some species live for hundreds of years.
Lighthouse jellyfish
The lighthouse jellyfish is the only organism found that can progress from sexual maturity to the larval stage. Under normal circumstances, jellyfish will die after reproducing the next generation. Only flagship jellyfish will return to the young stage after reaching sexual maturity and begin another life process. Theoretically, this cycle process can last forever. This is the legendary infinite resurrection.
Tardigrade
There are more than 900 species of tardigrades, with footprints all over the world, from the mosthigh mountains to the deepest oceans. Their size is only 1 millimeter, but their tiny bodies contain infinite vitality. Even if they are steamed, frozen, exposed to sunlight or placed in a high radiation environment, they can still survive for 200 years. Tardigrades can withstand a low temperature of minus 457 degrees Fahrenheit, a high temperature of 357 degrees above zero, and a radiation test of 5700 Gray. A radiation dose of 10 to 20 Gray is enough to kill humans and most other animals. Additionally, they are capable of surviving in space.
Under natural conditions, the lifespan is generally 50 to 100 years and can survive for decades.
Whales were once considered ancient animals, and their lifespans were thought to be up to 500 to 1,000 years. It is said that in fact the average lifespan is only 30 years,and the longest lifespan is not. exceed 100 years. ?
The lifespan of a beluga is generally thirty to forty years, the lifespan of a blue whale is at least eighty years, the lifespan of a Killer whale lifespan is typically twenty to thirty-five years, and the lifespan of a baleen whale averages forty to fifty years.
Although whales have large bodies, they are active all day long and don't even sleep yet. In terms of body size ratio, compared to other large animals, their material metabolism rate is extremely high, hence their lifespan. is relatively not long.
Detailed information:
Mammals generally reach sexual maturity when they reach 1 /8 to 1/6 of their lifespan, which corresponds to the time when fin whales reach sexual maturity, which is 8 to 10 years after birthnce, from there, its lifespan is estimated at 90-100 years.
In fact, the ages identified from the earplug scratches basically match the estimated numbers. Fin whales and blue whales are around 100 years old, and baleen whales are 70 years old. Of course, the lifespans. different whales are not the same. Among toothed whales, sperm whales can live up to 80 years, some dolphins have an average lifespan of 25 years, and true dolphins are 15 years old.
The bowhead whale, formerly known as the Arctic whale, is also known as the Greenland right whale, Greenland whale, giant polar whale, and Arctic right whale. It was first seen in Linnaeus's "Natural Classification" in 1758.
Bowhead whales have a rich voice that they use to communicate with each other during migration, feeding and interactions social. Some of these long, repetitive whale songs may be mating signals. Some individuals can live between 150 and 200 years, making them the longest-living whales on earth.
