To maintain continuity with the contents of PART - 2, the light-emitting photophores and electric organs are elaborated in CHAPTER - 1 and CHAPTER - 3, respectively, of this 'PART - 3' of the SERIES. 'Biofluorescence' is another curious phenomenon related with 'light' production (but differently from Bioluminescence) with the involvement of 'skin' and its components. The contents of CHAPTER - 2 will not only reveal the interesting aspect of 'Biofluorescence' in fishes but will also signify the role of skin and its components in causing fishes to fluoresce.
