From a young age, creatures that participate in ruthless competition – those born slower must become the food of their siblings.
The diverse life on Earth, and nature has always been very cruel, some creatures compete for survival from a young age. Their ways of survival may seem 'underhanded' to others, but that is precisely the cruelty of nature, 'survival of the fittest' is the most realistic portrayal of nature.
When it comes to those 'vile and ruthless' creatures, many people will immediately think of the cuckoo bird, because cuckoo birds are brood parasites and cuckoo birds do not raise their offspring.
So, it places its eggs in the nests of other birds, allowing other birds to raise them, and cuckoo birds have a shorter incubation period than other birds, and when they hatch, they push the offspring of other birds out of the nest, causing them to fall to their deaths from a height, and it will finally enjoy the food of adult birds. 'It might seem very despicable and cruel to many people, but this is the cruelty of nature, but when it comes to ruthless creatures, there is one that is terrifying from birth – competition.
This creature is the Mayfly, also known as the click beetle or scissors beetle. In summer, Mayflies begin to lay eggs, and can lay up to 90 eggs at a time. Their eggs are like plump grapes, but beneath this beautiful appearance is a cunning little Mayfly. Mayfly larvae are very competitive, and when they are born, they will unhesitatingly eat their unhatched siblings.
Therefore, the survival competition of Mayfly larvae is a race against time, and if they hatch slowly, they can only become food for their siblings. This might be the cruelty of nature! Stronger survival, weaker elimination. How do netizens see this?
