Scientific Name of Prawn

The scientific name of the prawn is Dendrobranchiata. Among the first shrimp subspecies discovered by scientists was the massive river prawn. The  prawn is a small aquatic crustacean with an exoskeleton and ten legs that belongs to the Decapoda group and can be eaten in some cases. Prawns are large swimming crustaceans or shrimp that have commercial significance in the fishing industry in the United Kingdom, Ireland, and Commonwealth countries. The Dendrobranchiata suborder is commonly seen in this group of shrimp. Freshwater shrimp are more generally referred to as “shrimp” in North America. The terms “shrimp” and “prawn” do not have a scientific definition. Shrimp and prawn definitions have developed over time, and the two names are now practically interchangeable.

Prawn 

The prawn is a member of the Arthropoda phylum and Crustacea class. It’s a well-known nutrient-dense and tasty food. Bangladesh has a variety of marine and freshwater prawn subspecies. A fresh – water species of Golda prawn. In response to various environmental structures, all prawn species have a lot in common. Bagda is a type of sea prawn.

Prawn Habit and Habitat

Species prawn can be found in rivers, ponds, and other freshwater environments. It is a bottom-dwelling nocturnal creature that dwells underneath cracks and aquatic plants. It eats a variety of foods, including rotting leaves. They are  a good swimmer, and it can also crawl on the surface and jump backwards in the event of threat. It can grow to be seventy-five cm long.

We can Classify prawn on these basis given below :- 

• Kingdom: Animalia
• Phylum: Arthropoda
• Class: Crustacea
• Order: Decapoda
• Family: Palaemonidae
• Genus: Macrobrachium
• Species: M. rosenbergii

Prawns Behavioural Characteristics

Physical characteristics 

Prawns are available in a wide range of shades, such as black, pink, white, and grey. A Palaemon prawn can grow to be somewhere between six and eight inches long when fully mature. Once caught, the fish has a subtle blue colour. It has a cylindrical and elongated body. The body of the prawn is somewhat flattened from one side to the other.

Location 

The northern regions are home to banana, brown tiger, and western king prawn fish. 

In Australia’s northern regions, you can find bananas and tiger prawns. Banana prawns are famous in the English town of Exmouth. Tiger Prawns can be found in Shark Bay. The king prawn fish may be seen all along Western Australia’s coast. These can also be spotted in Australia’s Swan River.

Palaemon Prawn

A Palaemon prawn’s body is separated into two halves. There are two parts, one of which is anterior and the other of which is posterior. A shrimp has an unjointed cephalothorax, which means it has six pairs of appendages or body parts attached to the main body segment. A prawn’s legs lack the joints that humans have in their knees to help them bend. The posterior of a Palaemon prawn has a jointed abdomen, but the anterior does not. The abdomen of the prawn protrudes from the remainder of the body. A prawn’s abdomen is separated into six divisions. The 6 segments each have their own set of appendages.

Its appendages are situated on the prawn’s bottom body’s ventral side. The prawn’s abdomen has two sections, one on the inside and the other on the exterior. On the outside, there is a telson. The telson is situated on the shrimp’s tail. At the other end of the abdomen is the cephalothorax. At this point, the prawn’s head and thorax meet. Around the thorax, the abdomen and neck form a protective barrier. At the bottom of the shrimp’s body are thirteen sets of appendages.

Body of the prawn 

The shade of a prawn’s body can shift depending on the circumstances. Due to the general pigment in their epidermis, that is located directly beneath their shell, they are able to do so. Because of the cells in their skin, they can change blue, yellow, red, yellow-white, and sepia-brown. The colour they turn is determined by the number of cells of that hue in their body. The cells cause pale spots in school prawns, but brilliant crimson or even scarlet markings in deepwater prawns. Deepwater prawns turn a rich crimson colour due to their oceanic habitat. They appear black since the colour isn’t visible. As a result, hunters will have a harder time spotting them.

Body of the prawn is divided into two main parts. 

1. Cephalothorax 

Cephalothorax:  It is also divided into two sections. 

The anterior section of the Cephalothorax is called the head. The a. Antennule, b. Antenna, c. Mandibles, d. Maxillula, and e. Maxilla are five pairs of segmented appendages in the head.

The thorax is located only behind the head. A Cephalothorax is made up of the head and the thorax. The first three sets of appendages, termed as Maxillipeds, are Maxilla-like. Walking is done by the last five pairs of thoracic appendages. Those legs are segmented, tubular, and elongated. First and foremost, Forceps are delivered with the second set of walking legs. Carapace is a rigid covering that protects the Cephalothorax. A set of black, spherical stocked compound eyes can be found at the front end of the carapace. Here between eyes is a flat saw-like rostrum that is laterally compressed.

2. Abdomen

An elongated section of the body behind the Cephalothorax is referred to as the abdomen. It’s dorsally spherical and a little squashed laterally. The abdomen is divided into six sections. A set of appendages can be found in each segment of the abdomen. Pleopods are aquatic animals that are employed for swimming. The very first five sets of swimming legs have a lot in common. The legs are segmented on all sides.

The uropod, often known as the tail fin, is the sixth and last abdominal appendage.

All of those are oar-shaped and quite large. Telson is the pointy region at the end of the abdomen.
