Not as many calories as eating shrimp will give you
The term "jumbo shrimp" does not reliably refer to any particular shrimp species. While most are smaller there are several species of shrimp (e.g. Black Tiger Shrimp or Scarlet Shrimp) in which individuals can weigh several pounds. As such the best answer I can give you is "one or more".
Eating spoiled shrimp will cause food poisoning. This can manifest in many ways. You may feel sick, have stomach cramps, vomit or get a headache. Usually symptoms will go away in a few days but if they don't, consult a doctor.

It can, but eating undercooked shrimp does not guarantee illness. That will depend on whether or not the raw shrimp carries the disease-causing microbes. But do not eat undercooked seafood. The risk is too great. One form of foodborne illness that some people don't realize is the use of sulfites on shrimp. Sulfites are used for color retention and many people are allergic to sulfites. Another concern is the use of antibiotics in farm-raised shrimp. See Related Links.
There are usually numbers that describe the size of shrimp. These numbers tell you approximately how many shrimp are in one pound. The larger the shrimp, the fewer it takes to make a pound. Ask the seller where you plan to buy the shrimp what the "count" of the shrimp is for the size you want. They can tell you how many shrimp will be in one pound. The largest shrimp I've purchased were (10-16) size. That meant there were from 10 to 16 shrimp in one pound. If you buy that type of shrimp, you'd need about 4 or 5 pounds to be sure you had 48 shrimp.
