Vannamei is a type of shrimp that has the best environmental resistance compared to other types of shrimp. This is supported by the presence of organ systems and morphology in vannamei shrimp.

Like humans, vannamei also has a digestive system, respiratory system, circulatory system, nervous system, and reproductive system. All of these organ systems must work properly for the vannamei shrimp to survive.

Curious about the organ system and morphology of vannamei shrimp? Let’s find out the answer to this article.

Morphology of Vannamei Shrimp

Overall, the morphology of vannamei shrimp is divided into two parts, namely the head and body parts. The head consists of eight thoracic segments and five fused head segments. Therefore, the head of this shrimp is also known as the cephalothorax.

The head of the vannamei shrimp is protected by a shell that tapers forward and is called the carapace. In addition, there is also a pair of compound eyes, a mouth with a jaw (mandible), a pair of antennae, a pair of head fins (scophocerit), a pair of auxiliary jaws (maxilliped), and five pairs of walking legs (pereopod) on the head.

The morphology of vannamei shrimp body parts consists of six segments, they are three tergum segments and three pleuron segments. In this part of the body, five pairs of swimming legs (pleopods) and fan tails are also found which are formed from uropods and telsons.

Organ System in Vannamei Shrimp

1. Digestive System

Vannamei shrimp have a digestive system that is divided into three segments, they are foregut, midgut, and hindgut that are connected to each other. These three parts are covered by a peritrophic membrane that serves as a barrier. Usually, this digestive system can be seen quite clearly on the back of the shrimp.

The foregut digestive tract is located in the cephalothorax, starting from the mouth, esophagus, and stomach. The midgut digestive tract is located extending from the cephalothorax to the 6th segment of the shrimp stomach. Lastly, the hindgut of the digestive tract is located at the back.

2. Respiratory System

Gills are the respiratory organs of vannamei shrimp and other crustaceans. In vannamei shrimp, there are a pair of gills enclosed in a branchial space. These gill structures are classified as dendrobranchiate gills. When shrimp breathe, gas exchange takes place in the gill lamellae.

Apart from being an organ for breathing, the gills of the vannamei shrimp also plays several other important roles. Starting from maintaining salt and water balance, ammonia excretion, and calcium absorption, to acting as a filter for foreign particles in the hemolymph.

3. Circulatory System

Even though it has a transparent white body, it turns out that vannamei shrimp also has a circulatory system like humans. This circulatory system consists of the heart, hematopoietic sinuses, hematopoietic tissue, and lymphoid organs.

The vannamei shrimp’s circulatory system is classified as a semi-open circulatory system with the heart located dorsally in the cephalothorax.

4. Nervous System

You must be familiar with the phrase “shrimp brain”, right? However, in contrast to the phrase “shrimp brain” which means stupid, the brain in vannamei shrimp has an important role in the nervous system.

The nervous system of shrimp and other crustaceans consists of a brain located in the dorsal part of the cephalothorax as the main control center that is connected to all parts of the shrimp’s body. The brain consists of three parts, which are the protocerebrum, deutocerebrum, and tritocerebrum.

5. Reproduction System

The male vannamei shrimp reproductive system consists of a pair of testes, vas deferens, and ejaculatory ducts or terminal ampoules. While the spermatids are produced in spermatogonia with maturation in the seminiferous tubules.

While the female vannamei shrimp reproductive system consists of paired ovaries that extend from the middle of the thorax to the posterior end of the pleon and oviduct. Because shrimp have an external reproductive system, female shrimp have a genophore channel located on the third pereiopod to release eggs that are ready to be fertilized.
