I've bolded the key part: as far as he (and I) know, marinum
is a low-temp bug. At least on my part, that's only a semi-educated guess, so I'm really hoping to find someone on here who can confirm that with some confidence/authority.
Please chime in if you have any of the education/knowledge to help me figure this out!
