Why do penguins have a poor reproductive rate but a large number of species?

In our daily life, although we can't get in touch with penguins at ordinary times, many people know penguins indirectly because of their lovely appearance. In people's impression, penguins are very simple and lovely creatures, but in the eyes of biologists, penguins are famous black-bellied creatures. Today, we will talk about the maximum number of Adelie penguins.

Why do penguins have a poor reproductive rate, but many species are in the Antarctic with snow all year round? Even the rulers in this area, although they don't have strong physique and high wisdom, do everything they can to survive. First of all, penguins breed through cloaca. Usually, male penguins ride on female penguins and reproduce. Because penguins can only export reproductive substances, the reproductive rate of penguins is generally low.

In addition, penguins breed only once a year in summer, and they don't choose to breed at other times, so it is very difficult to breed penguins. However, penguins always live in sparsely populated places, and there are no other creatures. Penguins have no natural enemies and can naturally live freely, which is also the reason why penguins have poor reproductive efficiency and large-scale species.

So, why are penguins called the "king of darkness" in the animal kingdom? Usually, penguins eat krill, squid and so on. They need to be caught in the water, but there are also animals that feed on them, such as seals. So before the penguins go into the water, they will quietly push the penguins next to them into the water. If penguins under water are not attacked, they think it is safe. If the penguins in the water are ambushed, they will change places. Sometimes penguins eat a lot of their own kind in one hunt.

On the Antarctic continent, there are many kinds of penguins, including Adelie penguins and emperor penguins. Usually, the size and weight of emperor penguins are the best among penguins, but this is not as dangerous as Adelie penguins. The breeding time of emperor penguins is staggered with that of Adelie penguins. However, emperor penguins sometimes need more time to grow in order to be safer. At this time, emperor penguins occupy the breeding space of Adelie penguins, so Adelie penguins will push their little emperor penguins into the water.
