In crustaceans, specifically decapods such as the crayfish, the stomach is divided into two parts: the first, or anterior part is called the "gastric mill". The gastric mill is lined with chitinous teeth which grind up coarse food particles. The posterior part of the stomach acts as a filter to keep coarse particles from entering the digestive glands, where absorption takes place.
The stomach of a crayfish contains a unique structure called the gastric mill, which is composed of chitinous teeth and is used to grind food. This specialized grinding mechanism allows crayfish to break down hard food items, such as mollusks and plant material, aiding in digestion. The gastric mill is an adaptation that reflects the crayfish's omnivorous diet and plays a crucial role in their ability to process food efficiently.
Muscles move the gastric mill. The gastric mill is a gizzard that is found in the majority of decapod crustaceans.
The function of the exoskeleton is to protect the internal organs and support the crayfish because it is an invertebrate.

Lobsters have their teeth in their stomach. They chew their food in their stomach, which is very close to their mouth, between three grinding surfaces that look like molar teeth called the "gastric mill".
A uropod is used for swimming. Telson does the same thing.
it is used for holding the long haul that the crayfish caught and then ate.
A rostrum on a crayfish is an extension of its shell. This part is used for extra protection.
The food that a crayfish consumes first goes through the gastric mill and into the stomach. Food then passes into the digestive system and digestive gland for further digestion and absorption. Undigested particles continue along the intestine and out the anus.
Uropods help the crayfish to accomplish the life process, movement. They also help steer the crayfish into the correct direction.
