Introduction

Worldwide presence animal there are different types of organisms with specific characteristics. In this article we will talk about the difference between two of them: acoelomates and coelomates.

Acoelomates

Acoelomates are organisms that do not have an internal body cavity, which means that its organs are in direct contact with the inner layer of the body, called mesoderm. These types of animals include flatworms, such as the tapeworm.

Not having an internal cavity, acoelomates have an elongated and flattened shape, which allows them to move in small spaces. Despite this, their digestive and circulatory systems are effective.

Characteristics of acoelomates:

• They do not have an internal body cavity.
• Its organs are in direct contact with the mesoderm.
• They are elongated and flattened animals.
• Effective mobility in small spaces.

Coelomates

Coelomates, on the other hand, do have an internal body cavity called a coelom, which is covered with mesodermal tissue. This type of animals includes humans, dogs, cats, among others.

The presence of the coelom gives greater protection to the internal organs and also improves the mobility and flexibility of the body.

Characteristics of coelomates:

• They have an internal body cavity called a coelom.
• The coelom is covered with mesodermal tissue.
• Improves protection of internal organs.
• Improves mobility and flexibility of the body.

Conclusion

In summary, The main difference between acoelomates and coelomates is the presence or absence of an internal body cavity. Coelomates have a cavity called a coelom, while acoelomates do not.
