Males of Melanocetidae do not (despite popular belief) seem to be parasitic; furthermore, postmetamorphic specimens have been found with prey items in their stomachs. Unfortunately, I have not been able to ascertain the exact nature of the prey since the research citations all seem to point to a paywalled book (and I am too scared of people to email any ceratioid researchers).
Does anyone here happen have further information on this subject? I am primarily interested in the size of the male’s swallowed prey items in comparison to its body.
