The Spiny Lobster(Panulirus interruptus) is a species in the Arthropoda phylum.Its digestive system is different than many other organisms. The spiny lobster eats its food whole and has its stomach do the chewing.The Stomatogastric ganglion controls the rhythmic contractions of the stomach and gastric teeth. The lobster has two different rhythms for digestion. The gastric rhythm controls the calcified teeth that lay within the gastric mill of the lobster. The pyloric filter, a system of valves and sieve plates that helps sort out the food particles so that they may be further digested, is controlled by the ploric rhythm. The rhythms are coordinated contractions of groups of muscles.
