Diet Lobsters usually move around and hunt for food at night. It was once thought that lobsters were scavengers, and ate primarily dead things. However, lobsters are really more opportunists, catching ...

2019-4-1  In contrast to results reported by Sheridan et al., we did not find the ossicles of the gastric mill loose within the stomach of the lobster immediately after ecdysis. Instead, they were attached to the cardiac sac. However, the ossicles were soft and translucent indicating decalcification, and it took 24–48 h for these to re-harden.

1999-4-15  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.

Gastric Mills: Teeth in the Stomach - The Infinite Spider

2014-6-10  The gastric mill is found in crabs, lobsters, crayfish, barnacles, krill, and many others. These invertebrates don't have teeth in their mouth to grind their food, so they process it a bit differently. Their claws rip and tear apart their food (mostly plants and

2020-10-6  Gastric Mill. A lobster’s teeth are located in its stomach! These teeth are part of a system called the gastric mill which crushes food so that it is ready for further digestion. Lobsters swallow their food whole and the three teeth in their stomach act like grinders, enabling the stomach to do the chewing.

2019-4-3  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.

2021-11-24  A freshly-laid lobster egg is the size of the head of a pin (1/16"). A 1-pound female lobster usually carries approximately 8000 eggs. A 9-pound female may carry more than 100,000 eggs. The female lobster carries the eggs inside for 9 to 12 months and then for another 9 to 12 months attached to the swimmerets under her tail.
