Just prior to the start of Yom Kippur this year, a young child corrected me when I mentioned Yonah's whale and said that, "it wasn't a whale; it was a Dag Gadol."
I had to admit, this was good teaching on the part of the teacher. Or was it?
I understand that today's classification of animals categorizes a whale not as a fish but as a mammal. But does this mean that Yonah's "Dag Gadol" necessarily wasn't what we would today call a whale?
I don't mean to ask for a definitive answer as to what species of sea creature swallowed Yonah. I am just trying to find out if anyone has written anything convincing (or widely accepted theologically), of which I'm unaware, that states, "No, it was not a whale; it was a Dag Gadol."
