Question

1. How many stomachs does a crayfish have? What are they called?

Answer 1

Crayfish have a single stomach with two parts, including a gastric mill, and they have a connected digestive gland. Their digestive system is part of the unique anatomy of crustaceans, which also includes a carapace and the process of molting for growth.

Step-by-step explanation:

Crayfish, like other crustaceans, have a specialized digestive system that includes different compartments for processing food. Nonetheless, crayfish do not have multiple stomachs as some animals do; they have a single stomach with two main parts and associated digestive structures. The main part of their stomach, known as the gastric mill, is comparable to a gizzard in that it uses hardened plates to grind food. The other section of the stomach closely associates with a digestive gland, sometimes referred to as the hepatopancreas, which helps with the absorption and digestion of food.

Crustaceans such as crayfish have many unique features; they have a hard exoskeleton known as the carapace and they shed their outer skeleton through a process called molting in order to grow. Additionally, crustaceans generally have a compound structure forming the front part of the body, called the cephalothorax, which is protected by the carapace.

Answer 2

It is called "Gastric Mill" They have 3 stomachs

Step-by-step explanation:

The teeth are part of a system called the “gastric mill.” Through rhythmic movements of these large teeth, of which there are three, their stomachs can actually crush food as a prelude to further digestion.
