What is the difference between the cephalothorax and abdomen of a crayfish?

The abdomen is located behind the cephalothorax and consists of six clearly divided segments. The cephalothorax consists of 3 segments. Each segment of both the cephalothorax and the abdomen contains a pair of appendages. The head (or cephalic) region has five pairs of appendages.

What is a cephalothorax abdomen?

The cephalothorax or prosoma is the anterior most of the two body parts of arachnids (the other part being the abdomen or opisthosoma). The cephalothorax features the eyes, mouth and legs of the arachnid. The cephalothorax is more rigid than the abdomen and contains the muscles used to operate the limbs.

How can you distinguish the cephalothorax of your specimen from its abdomen?

The main difference between the cephalothorax and the abdomen is that the cephalothorax consists of the fused head and thorax and has 13 segments. The abdomen is divided into 7 segments.

What connects the cephalothorax to the abdomen?

Spiders, unlike insects, have only two main body parts (tagmata) instead of three: a fused head and thorax (called a cephalothorax or prosoma) and an abdomen (also called an opisthosoma). ... The abdomen and cephalothorax are connected by a thin waist called the pedicel.

Is the cephalothorax or abdomen more flexible in a crayfish?

The abdomen is flexible and the segmentation is visible here. The appendages of the crayfish attach to both the cephalothorax and the abdomen.

What is the function of the Maxillipeds?

Maxillipeds are appendages modified to function as mouthparts. Particularly in the less advanced decapods, these can be very similar to the pereiopods. Pereiopods are primarily walking legs and are also used for gathering food.

What is the main difference between the cephalothorax and abdomen in crustaceans?

Cephalothorax is a fusion of two main body regions, whereas the abdomen is one distinctive region.

Where is the cephalothorax?

What is a cephalothorax used for?

4) is divided into two main regions, the cephalothorax and the abdomen. The cephalothorax, a fused head and thorax, contains the internal organs including the digestive system, the heart, and the gonads.

What is the purpose of the Telson and Uropod?

In the middle of the uropods is a structure called the telson, which bears the anus. The uropod and telson together make up the tail fan. The crayfish moves backward by forcing water forward with its tail fan.

What is the difference between the function of the antennae and Antennules?

The antennules are organs used for balance, touch, and taste. Long antennae are organs used for touch, taste, and smell.

What is the function of Telson?

What is the function of the telson? It is the tail - it allows the crayfish to escape enemies and is also used for swimming.

Is cephalothorax found in earthworm?

Option C Cephalothorax: The cephalothorax, also known as the prosoma, is the most anterior of the body sections. The cephalothorax features eyes, mouth. The cephalothorax is more rigid than the abdomen and contains the muscles used to operate the limbs.

Is cephalothorax found in prawn?

Cephalothorax: Cephalothorax is the broad, un-segmented and cylindrical anterior part. It is formed by the fusion of head and thorax. In fact, during the development of prawn, one pre-segmental region and first fourteen segments fuse to form cephalothorax.

Do spiders poop?

Spiders excrete thick, liquid droppings from their anal opening which land on the surface below. Spider droppings are a combination of digested food (insects) and waste products. The droppings look like pin head-size splats or drips in shades of white, gray, brown, or black.
