对河马我没有深入研究。练习【满江红】概述读过的几篇关于河马的文章：
【河马】
戏水逐流，扑腾处，浪花激烈。寡言语，仰颈长啸，有时坑爹（1）。三十腰围太细了，八千磅重不算轻。 家规严，乌墨油亮头，黑如铁。
性温和，水陆歇， 恶冰冷，喜阳光。大嘴巴，血汗防皮干裂。 自古丛林有法则，弱肉强食有正邪。 怀远见，计划如何生育，不孤绝。

Hippopotamus Habitat
You will find a group of Hippos living in the lakes and rivers. Sometimes the groups are very small with only about five members. They can be as large at to have thirty members though. It depends on if there is enough room for their basic needs to be met. They do like to live in deep bodies of water. When they have young, the mothers will often carry them on their backs so that they aren’t so far below the surface of the water to get to air.
There are two species of Hippos and they prefer different types of habitat. For the Common Hippo, they live mainly in the Eastern part of Africa around the Sahara. They are the more aggressive type of Hippo and the ones that are often known to be eating the crops that villagers have planted for their own needs.
They are found living in clean bodies of water that don’t move very fast. They do like it deep enough for their bodies, but not too deep. They also prefer a bottom that is easy for them to move around in. If there are many rocks it can be something that slows down the Hippos and even injures them as they move around.
The habitat for the Pygmy Hippos is different as they like to live in the swamplands. They like water that is murky and they don’t care if it is deep or if it has rocks at the bottom of it. However, they are smaller in weight so that could be part of the reason why such factors aren’t a burden to their movements.
The number of Pygmy Hippos living in the wild today is extremely small. They continue to have their surroundings invaded by villagers that want to plant crops or that need more living space due to their growing populations. Today you will find them only in the forest area of the Western part of Africa.
Even if you don’t seem to really care about Hippos, you need to be aware of what they contribute to their ecosystem . Without them being part of the habitat out there, imbalance and chaos would result. This could lead to future population problems for many animals – for some it can even mean future extinction. Preserving the natural habitat out there of the Hippo should be a concern for everyone. The rippling effect can adversely affect everyone and every animal.
You will find that many Hippos live in captivity. Yet very seldom are they taken from the wild anymore for this purpose. Instead, those that are born into captivity are often going to spend their entire life that way. Hippos do very well in captivity and most of the zoos have Pygmy Hippos to help keep their numbers up.
Many experts would love to experiment with the idea of introducing some of the young Hippos that are in captivity back into the wild. Yet what has been observed out there is that the remaining Pygmy’s are fighting for enough living space in the water and enough food on land as it is. Adding more of them at this point in time isn’t a realistic solution to consider.
The fact that we have only began to really understand all that takes place in a Hippo habitat is part of that equation as well. Until we know the entire process inside and out we won’t be able to come up with some good plans for increasing the number of Hippos in the wild. However, right now we do need to focus some attention on making sure the current numbers don’t continue to plunge.
