Reply to comment by CrackBingeIdea in TIL in 1962 a General Electric engineer named Nick Holonyak developed the first LED light bulb capable of emitting visible red light. The same bulb was used in the 1964 stop animation animated TV special Rudolph the Red-Nosed Reindeer for Rudolph’s bioluminescent nose. by undergroundgeek

Not at all. There are tons of non-bacteria bioluminescent organisms.
The example that leaps to mind being fireflies.

It seems so, bio means life and luminescent means to produce light so it's simply any living organism which can produce light.

Yeah, now it seems obvious... I just always figured it needed some symbiotic bacteria existing within an organism. Huh. Thanks man, every day is a school day.

It's an understandable assumption IMHO. My mind goes directly to algae when bioluminescence is mentioned, simply because it's the only form I've seen firsthand, and was around it quite a bit.
