In summer, we often see groups of tadpoles in ponds, paddy fields and ditches. When these little tadpoles get together, are they really going to find their mother? We often use bees to describe a person's diligence. Are bees really industrious? There is no room for two tigers in one mountain, unless one is a male tiger and the other is a female tiger, so why do Siberian tigers huddle together to keep warm? In this issue, let's take an inventory of some interesting things about animals living in groups.

Some excerpts from Science focus 2023.10

In order to resist natural enemies and improve survival, the larvae of amphibians such as tadpoles are more willing to move in groups, just like children go to school. This "tadpole school" is usually made up of siblings.

This is not just about winning in terms of numbers in the face of security issues. These tadpoles can also use their collective sense of smell to find food and improve the success rate of foraging. Tadpoles are mostly herbivorous and usually scrape algae from solid surfaces. Of course, they also feed on dead animals.

In addition, they can use their sense of smell to recognize their brothers and sisters. But when they lose their tails, grow legs and lungs, jump on land and become frogs, this recognition disappears completely.

Just as humans often lose infancy memories, this forgetting may be designed to increase the overall reproduction rate of the frog species. Because brothers and sisters have to separate to hunt and reproduce on a larger scale, but under the pressure of life, the skill of sniffing out brothers and sisters is less important.

Industrious bees, random drones We know that bees are a kind of highly social insects. In a colony, each bee has its own responsibility. For example, three types of bees live in each hive: worker bees, drones and queen bees. Among them, worker bees and queen bees are female. The queen bee is fertile, is responsible for laying eggs, and is larger than the worker bee. Drones are male. They have larger compound eyes, but no stings.

Honeybee hives are usually beautifully designed and built because they are usually responsible for supporting up to 40000 bees to live together for several years.

The drones' nests are disorganized, separated only by leaves or animal furs. Drones' nests only need to accommodate a small number of drones (about 40 to 400) in one nesting season.

Some parasitic drones, such as red-tailed drones, never build their own nests. Their queen bees invade the hives of other drones, kill the queen bees, and then lay eggs inside, allowing the worker bees in the hive to raise larvae for them.

We often use bees to describe a person's diligence, but not every bee is industrious. The queen bee lays 1500 eggs a day; worker bees feed, feed their young and take care of the hive every day; while drones have nothing to do every day, their only task is to mate with the queen bee.

Rich lions and poor tigers are also big cats. Why do tigers live alone and lions live in groups? This is related to the prey density in both living environments. Due to the low density of prey in the living environment, male tigers usually occupy a territory. On the other hand, the prey density of the prairie is very high, which gives lions the capital to live in groups. At the same time, lions also need to stabilize their territory by living in groups (whether in the face of intraspecific or interspecific competition, and whether they are actually improving their combat strength. Or reduce the psychological pressure of fear.

Hunting on the open prairie, on the one hand, it is difficult for predators to hide themselves, and there are multiple ways for prey to escape, so lions need teamwork; on the other hand, high density of prey also means more predators / rotten predators. After the lion succeeds in hunting, animals such as vultures and hyenas will come out to grab the results, which a lion cannot cope with.

On the other hand, tigers in the forest usually take advantage of various environmental conditions to engage in ambushes, and the fruits of successful predation can be enjoyed on their own, and it is no problem to eat slowly for more than ten days.

However, many people are impressed by the warm images circulating on social media of Siberian tigers lying in the snow of the Northeast Tiger Garden. Why do these Siberian tigers gather around to bask in the sun? First, in the artificial environment such as the Northeast Tiger Forest Park, the food is abundant, which is equivalent to the tiger experiencing the taste of "rich nourishment." second, it is too cold in winter in the northeast, and huddling together is to keep warm, just like the little penguins huddling to keep warm in Antarctica, that is to say, heating is also a major reason why animals in nature choose to live in groups.
