Early this year, conservationists in South Africa found that two giraffes were killed by lightning, indicating that this tall species is at risk of lightning stroke. It seems that they are vulnerable to lightning strikes. They are equivalent to “lightning rods” on African grasslands, and this risk has been seriously underestimated. < / P > < p > the giraffe is the world’s tallest animal, and it is vulnerable to lightning attacks, which does not seem surprising, because taller objects tend to absorb Lightning more easily, especially in the open savannah of Africa. However, the number and frequency of animal death caused by lightning is a complete mystery. There are very few recorded cases, and the specific cause of animal death is difficult to verify. Earlier this year, two giraffes were killed in a lightning strike at Rockwood Private Reserve in South Africa. This case adds valuable research data to the scientific literature. < / P > < p > the giraffe is the world’s tallest animal, and it is vulnerable to lightning attacks, which does not seem surprising, because higher objects tend to absorb Lightning more easily, especially in the open savannah of Africa. However, little is known about the risks faced by giraffes. When the two giraffes were found dead, I tried to find scientific reports on the death of giraffes caused by lightning strikes, but surprisingly, I found only a small number of research reports published in non scientific journals. At the same time, the report rarely provides specific details, especially about the giraffe’s movement patterns and habitat. < / P > < p > Rockwood Private Reserve is located 180 km west of Kimberley City, South Africa. The natural environment protectors of the reserve are mainly concerned about rhinoceros protection, but the park is also home to Buffalo, zebra and other animals. < / P > < p > in 2017, six giraffes were introduced into Lockwood Private Reserve, and two more were introduced a year later. These eight giraffes were monitored almost every day, including February 28, 2020, the day before a severe thunderstorm hit the reserve. “We usually have thunderstorms and rainfall in the summer, but the newspapers rarely describe such extreme storm weather,” shynen said He is an ecologist at the Rockwood Private Reserve nature reserve foundation. < / P > < p > on the first day after the storm, only six giraffes were found in the reserve, which is very rare. On March 2, they found two dead giraffes, young females, only seven meters apart. < / P > < p > among the dead giraffes, the older was 5 years old. They had almost no scars on their bodies, but there was a serious wound at the bottom of the right antler, which refers to the antler like protrusion of the giraffe’s head. According to a study in the Journal of African ecology, researchers examined the giraffe’s skull and found that it had been struck by a direct lightning strike on its head. < / P > < p > the second dead giraffe was 4 years old and showed no signs of physical injury. It is likely that she was struck by a side lightning, in which a human or an animal will be electrocuted as long as it is close to an object struck by lightning. In this case, the old giraffe is more likely to die. Another possibility is that the cause of its death is the step voltage, which means that when lightning strikes the area near the animal, the voltage is generated when the current flows through the ground. As early as 2016, a lightning bolt in Norway and subsequent step voltages could have killed more than 300 reindeer. < p > < p > at present, shienzhen’s research report is only based on one lightning strike incident. It is more like a case report than a complete research report. She pointed out that the main purpose of her article is to let researchers understand the situation, stimulate their curiosity and attention, and then trigger in-depth discussion and research. < / P > < p > in fact, lightning strikes giraffes cause some important problems. Due to the giraffe’s height, it seems inevitable to be struck by lightning. An adult giraffe is between 4.6 and 5.8 meters in height. Therefore, it is natural that the species should evolve protective behaviors, such as seeking shelter in a storm, including areas with dense vegetation, or growing Areas with tall trees. < / P > < p > “one of the interesting questions is whether giraffes have learned to find shelter in thunderstorms, and if so, do they need to learn from older giraffes?” < / P > < p > the two dead giraffes in Lockwood Private Reserve died on the open grassland, and there were few plants and animals around that could reach 4-5 meters high, making them the “highest point” of the area, as pointed out in the study. However, scientists ultimately don’t know if giraffes have adapted to thunderstorms, so more research is needed to answer this question. < / P > < p > first, it is important to determine whether lightning has an impact on giraffe evolution, because natural selection only works when the frequency of lightning events occurs. If natural selection really works, scientists have to figure out which giraffes are going to be eliminated, the tallest giraffes, the ones who haven’t sought refuge, or those who live in high-frequency thunderstorms, she explained? “Second, we have to find out whether giraffes adjust their behavior according to weather conditions, and are they likely to migrate to areas where trees are bigger and denser,” Shenzhen said? When there is a big storm, do they bow their heads? ” < / P > < p > it is worth noting that giraffes form longer necks and higher body sizes due to natural selection, which may be a more powerful factor in their evolution. < / P > < p > “if the body is tall and strong, it will increase the chance of mating and breeding. Even if it is the highest animal with a low probability of being hit by lightning, the height feature is still an” advantage. ” < / P > < p > more research may help answer these interesting questions, and fortunately, shyne and other scientists will continue to work on these extraordinary creatures.
