Abstract: Morphology and histology of brain and ultrastructure and distribution of lipofuscin in brain were investigated inmantis shrimp Oratosquilla oratoria by biopsy，fluorescentmicroscopy and transmission electron microscopy to research the characterization ofmorphology，distribution and ultrastructure of lipofuscin in the brain.The brain was found in the rear of ophthalmic segment and in the small sharp point of cephalothorax，and histologically the rounded cerebral nucleus with diameter of 10-30μm was distributed uniformly in the brain，especially aggregated in the protocerebral bridge cellmass.Under fluorescentmicroscopy，the lipofuscin granules with diameter of 1-3 μm were yellow-brown in color and uniformly distributed in the brain.The transmission electron microscope revealed that lipofuscin was similar to the lysosome in thatboth were covered by single-layered organellesmembrane，and in the granules filled with homogeneous electron-dense contents.The findings indicated that the lipofuscin granules in brain of the mantis shrimp had similar form to other crustaceans and uniform distribution in brain.
