The existence of coelenterazine in various nonluminous organisms suggests that some of the coelenterazine-dependent luminous organisms might obtain coelenterazine from their food, either as the sole source of this substance or as a supplement to the coelenterazine biosynthesized in the body. In the case of the hydrozoan Aequorea aequorea, it was reported that the medusa is unable to produce its own coelenterazine and is dependent on a dietary supply of this compound for its capability of bioluminescence (Haddock et al., 2001). The organisms that biosynthesize coelenterazine remain to be identified, but it seems to be a common opinion at present that at least copepods do make their own coelenterazine. According to Thomson etal. (1995), the shrimp Systellaspis debilis is capable of coelenterazine... 

Regarding the polychaete Tomopteris, the author has briefly examined its bioluminescence using a few specimens donated by Dr. Steven Haddock. The specimens did not show a luciferin-luciferase reaction, as noted by Harvey (1952). The luminescence could be...

A rearrangement involving a fluctuating 1,2,3-thiadiazole ring has been found by Haddock et al. (1970) after diazotization of 7-amino-6-substituted 1,2,3-benzothia-diazoles (Scheme 6-46).

Reductases play a cardinal role in the anaerobic degradation of diverse aromatic compounds, for example, (a) the reduction of benzoyl-CoA that is a prelude to the fission of the ring (Harwood et al. 1999) (Chapter 8, Part 3) and (b) the degradation of phloroglucinol via dihydrophloroglucinol to acetate and butyrate (Haddock and Ferry 1989, 1993) (Chapter 8, Part 4).
