Digestion The digestive system of penaeid shrimp larvae is very simple and lacks a gastric mill and fil- ter apparatus during herbivorous stages. The existence of the anterior midgut diverticulae (AMD) along with the small hepatopancreas (HP) has been described by Lovett & Felder (75, 76) for P. setiferus and by Abubakr (50) for P. japonicus, P ...

C. cavipes are generally found in shores and sheltered lagoons, where they have access to both land and water. They are also found in mangroves where they use trees as shelter [3] or at mangroves where there are sandier substrates. C. cavipes, just like other land hermit crabs, reproduce and spend their early stages in water.Even though C. cavipes is a land hermit crab, …
1. The gastric central pattern generator (CPG) driving the three teeth of the gastric mill inside the lobster stomach has often been used as a model for the study of central nervous systems, but the actual functioning of the mill has never been observed directly. By using a small endoscope inserted …
The gastric mill is made up of two regions: the cardiac stomach (which is near the head end) and the pyloric stomach (which is towards the posterior). Digestive gland (The hepatopancreas) The gland functions as a liver, pancreas, and intestine for the shrimp (all in one). Additionally, it absorbs digested nutrients and can store it for some time.
The anterior chamber is distensible, particularly in the anterior part; it is sometimes called the 'food sac'. There are a pair of ventro-lateral, elongate plates, each of which bears a row of small teeth, which lead to the much heavier armature of the lateral teeth of the gastric mill and the single, dorsal median tooth.
Malaysia's Richest. ... The lobster's primary plastic-grinding tool is its 'gastric mill' - a complex body part made of seashell-like plates that grind against one another, similar to …
The teeth of a lobster are in its stomach. The stomach is located a very short distance from the mouth, and the food is actually chewed in the stomach between three grinding surfaces that look like molar surfaces, called the "gastric mill."
Morphology of the Gastric Mill. Prior to SEM analysis, the ossicles of the gastric mill were cut away from the stomach lining, and dehydrated in graded ethanol followed by hexamethyldisilazane. Samples were then mounted on stubs and gold coated (Allardyce and Linton, 2010). SEM images were obtained using a Jeol JSM-5200 scanning microscope.

Crustaceans, a commercially important class of arthropods in fisheries and aquaculture, represent a major worldwide food component for human consumption. Recently, growing interest regarding the ageing and longevity of crustaceans has led to advancement in the field of age determination methods, including the use of lipofuscin and growth band counts, …
A lobster does have teeth — but they are not in its mouth, they are in its stomach. The food is chewed in the stomach between by what look like three molars. These are called the "gastric mill". What color is a lobster? Most lobsters are a greenish brown color …

The lobster uses its claws in the feeding process, with the crusher claw being the larger of the two. Appendages near the mouth, called maxillipeds, direct the food to the jaws. The food passes from the mouth to the three-chambered stomach by a short esophagus. In the mid-chamber, the gastric mill, a set of chitinous teeth grinds the food.
The first of these rhythms is the gastric rhythm. This rhythm is responsible for the control of the calcified teeth that lay within the gastric mill of the lobster. Food moves from the cardiac sac into the gastric mill and is macerated by the action of the lateral and medial teeth. The second well characterized rhythm is the pyloric rhythm.

However, some particles passed into the "gastric mill," a complex of small calcified plates that grind against each other to break down food in a lobster's stomach. This process fragmented some of the plastic into smaller particles, which then moved on to the lobsters' intestines.
