The Ja­panese Pinecone Fish sup­pos­edly glows: it’s not only the body that makes it lu­mi­nes­cent, but also the bac­te­ria!

Ac­cord­ing to a 2008 ar­ti­cle writ­ten by Kathryn Snavely for The Gale En­cy­clo­pe­dia of Sci­ence, there are two phos­pho­res­cent or­gans on the lower jaw of the Ja­panese Pinecone Fish that at­tracts the bac­te­ria, which main­tain a sym­bi­otic re­la­tion­ship with their host.

The bi­o­lu­mi­nes­cence varies from a yel­low tint to a bluish-green color, de­pend­ing on how much light man­ages to reach the fish, ac­cord­ing to a 2014 ar­ti­cle about the pinecone fish in the RW Sen­tosa Blog.

It still isn’t known ex­actly what those or­gans are for but there are sev­eral guesses: im­prov­ing vi­sion, find­ing prey, or com­mu­ni­cat­ing with other ma­rine life.
