What do you know about hippopotamus?

1. Which of these animals do hippopotamuses most commonly coexist with?

Sharks

Crocodiles

Tigers

Pythons

Hippopotamuses most commonly coexist with crocodiles. Both species are often found in the same habitats, such as rivers, lakes, and swamps. Crocodiles are known to prey on young or weak hippos, while adult hippos are capable of defending themselves against crocodile attacks. This coexistence is a result of the overlapping ecological niches and resource availability in their shared environments.

2. Where do hippos spend most of their day?

In water

On land

In mud

Under a tree

Hippos spend most of their day in water. This is because they are semi-aquatic animals that are adapted to living in aquatic environments. They have a dense body structure that allows them to float and move effortlessly in water. Additionally, spending time in water helps to regulate their body temperature and keeps their skin moisturized. While they do come on land to graze and rest, the majority of their day is spent in water.

3. Other than Hippopotamidae, which of these evolved from Cetruminantia?

Ruminantia

Cetacea

Artiofabula

Both A & B

Both A & B evolved from Cetruminantia. The question is asking which of the given options evolved from Cetruminantia other than Hippopotamidae. The options Ruminantia and Cetacea both belong to the group Cetruminantia, so they are the correct answer. Artiofabula is not a part of Cetruminantia, so it is not the correct answer.

4. What's the average height and weight of a hippopotamus?

7 feet long and 3 feet tall

11 feet long and 5 feet tall

14 feet long and 7 feet tall

17 feet long and 9 feet tall

The correct answer is 11 feet long and 5 feet tall. This suggests that the average height and weight of a hippopotamus is approximately 11 feet long and 5 feet tall.

Explanation

The correct answer is 11 feet long and 5 feet tall. This suggests that the average height and weight of a hippopotamus is approximately 11 feet long and 5 feet tall.

5. What's the approximate bite force of the hippopotamus?

1,600 kPa

8,600 kPa

12,600 kPa

18,500 kPa

The approximate bite force of the hippopotamus is 12,600 kPa.

Explanation

The approximate bite force of the hippopotamus is 12,600 kPa.

6. Which of these is the closest relative of the hippopotamus?

Pig

Whale

Elephant

Horse

The correct answer is Whale because the hippopotamus and the whale are both mammals that share a common ancestor. They have similar physical characteristics such as a large body size, a streamlined shape, and a blowhole. Additionally, both animals spend a significant amount of time in water and have adaptations for aquatic life. While the other options are also mammals, they are not as closely related to the hippopotamus as the whale.

7. Which of these is true about hippos?

Hippos are the fastest swimmers.

Hippos can't jump on land.

Hippos can't survive even a single day without food.

None of these is true.

Hippos are known for their inability to jump on land. Despite their large size and powerful bodies, their anatomy and muscular structure do not allow them to perform jumping movements. While they are excellent swimmers, they are not the fastest swimmers. Additionally, although hippos do require a significant amount of food, they can actually survive for several days without eating. Therefore, the correct statement is that hippos can't jump on land.

8. As per genetic evidence, in Africa, hippos showed ___________ after the Pleistocene.

Population extinction

Population stability

Population reduction

Population expansion

According to genetic evidence, hippos in Africa experienced a population expansion after the Pleistocene. This means that the number of hippos in Africa increased significantly during this time period. This expansion could be attributed to various factors such as favorable environmental conditions, availability of resources, or successful reproduction and survival rates.
