Sea crabs

Question:  What is the range in sea crab size? Are any extinct?
Bob W Whitbeck

Answer:  Crabs have quite a size range in the ocean.
They range from the microscopic larval crabs to huge crabs that
are about four feet all the way across their bodies.  (There are
probably many even bigger, those are just the crabs that I've seen.)
There are many varieties of crabs that live in the ocean, and
yes, many of them are now extinct.
