This phrase farther up the thread caught my eye:
"mild-mannered innumerable inoffensive guppies "
I distinctly remember that my guppies, while they lived on fish food, would eat smaller fishes (such as baby guppies) whenever opportunity offered.
“Macro” nutrients means the big bulk categories - protein, fats, & carbs. The vitamin question isn’t addressed in there though. Overall, they need more or less the same complement of vitamins that we do.
Bony (non-shark) fish mostly don’t synthesize vitamin C, and I thought the same true of sharks; however the below article tells us that “primitive” fishes including sharks and lampreys DO synthesize vitamin C: Ascorbate synthesis in fishes: A review. I didn’t know that!
Beyond that, I’m finding many references that fish (in aquaculture) are best grown with fish meal and fish oil, as this is the “right blend of nutrients”, but not any hard quantification for sharks - pastrami is likely missing a few that they get through diets… I also learned that bottled phytoplankton is a woo health supplement at $30/1oz bottle… forget the pastrami, the sharks are getting the expensive stuff already.
And the person who made them the sammich.
What a bizarre question. Sharks love corned beef and knishes but never eat pastrami.
Is that the one that – at least in jungle legend – bites “nuts”? :eek:
I hadn’t heard of that, but Wikipedia does have section claiming that it’s a false rumor: Pacu - Wikipedia
They do eat tree nuts, though.
Apparently not:
DO SHARKS REALLY NOT LIKE HOW HUMANS TASTE?
Man the Serens keep a’Dipping on this topic. Uncanny. (Tuna joke not intended.)
I believe this thread has jumped the shark! 
That’s true according to the local chamber of commerce. Every time somebody gets bitten by a shark they come out with a press release about “investigatory bites”. You see, the poor sharks have limited tools to explore their environments with, and most of those tools turn out to be teeth.
Threadspotted.
Yes, but be reasonable:
Q: How the Hell is it going to hit the lever on the Deli ticket dispenser with a fin?
How is it going to hold its ticket?
and last but not least…
How is it going to keep from drying out while waiting in line?
Bonus Points: If it knew it was about to die & needed the pastrami, whats to keep it from biting all the old ladies in front of it in half…?
“Clean up… Deli… stockboy to Deli Dept…”
Well that’s OK then. Because if there’s one thing I can’t stand it’s being eaten to stave off hunger. But I’m a pro-science person. Being eaten for research is something I can live with.
Wait, let me re-phrase that…
