This study aimed to develop a data base of Coelacanth Fish, especially the type Latimeria menadoensis, as rare and endangered species of fish. The activities were under-taken an exploration activity, which took samples of the fish that have been caught. Samples were analyzed of the histological aspects of the anatomy of the internal organs. The data base can be used to support conservation efforts coelacanth fish. Base on microscopic observation, histological structure of the hull looks like the hull higher vertebrates that have four layers are: mucosal, submucosal, muscularis and serosa. In the microscopic description, bubble pool is a solid substance that is filled with grains of fat. Fat granules in the swim bladder serves as an energy reserve and to maintain the position of the fish in the water. Type swim bladder so commonly found in fish tend to move horizontally or does not have a rapid vertical movement.

The swim bladder of L. menadoensis is a solid substance without the cavity containing fat deposits that serves as energy and setting a position (bouyancy).It has not been revealed clearly, what the coelacanth also resembles gastric function in ruminants. Life span of the coelacanth fish until the age of 60 years based on growth rings visible on the scales. Using  a microscope with 20x magnification can be predicted that the age of the coelacanth fish based on growth rings was 27 years old. Latimeria menadoensis has two pyloricceca. Caeca short form and clogged pyloric end. The development of pyloric Ceca is an evolutionary strategy to increase intestinal surface area effectively without having to increase the length or thickness of the intestine. Pyloric Ceca serves as a digestive organ and can enzymatically as nutrient uptake is similar to the front of the intestine.
