On our planet, there are many species of marine life that choose to live in groups. For example, elephants, seals, killer whales, and various fish are familiar to us. So, why do these animals come together?
Marine organisms flock to survive and reproduce. This is because, in a large collective, they are better able to deal with various threats from the outside world. For example, when encountering natural predators, individuals in a cluster can use numerical superiority against the enemy. And, because of the close ties between the members of the group, they are also able to share resources more effectively and cooperate in predation activities.
In addition, for many fish species, the colony is also of great reproductive importance. Females come to an area of water at certain times to spawn. At this time, the male fish will also rush over to mate with them. In this process, dense groups help to increase the success rate of fertilization.
While there are many benefits to living in a cluster, it's not without its risks. Because once the group is too large, it puts pressure on the food supply. At the same time, large-scale migrations or migrations can lead to conflicts within populations. Therefore, how to maintain the appropriate cluster size is also one of the important issues that marine organisms need to face.
The choice of a marine organism to live in groups is a manifestation of adaptation to changes in the environment. It is good for both self-protection and reproduction. The existence of this phenomenon has undoubtedly made the earth's ecosystems richer and more diverse. Therefore, we should respect the uniqueness of each life form and provide them with a good living environment as much as possible.
