I was in a snack shop and reading the labels and came across "Thailand Sleeve Fish Slice" on what appeared to be a package of dried squid. I found limited results indicating that it does seem to refer to squid but very little else.
Sleeve fish on thefreedictionary.com
Webster's (looks like the source of the first)
Other results were suppliers or manufacturers of such snacks.
I'm interested in where the term comes from and if there is a difference or reason for its use instead of the more common "squid".
