What is the biggest mouse?



  1. 0 Votes

    The answer depends on where precisely one draws the borders of the term “mouse”. There’s a strain of mice on Gough Island in the Atlantic that’s descended from the common mouse whose isolation has allowed it to grow quite large and is the possibly the biggest in the world. A South American species called the Pacarana was originally classified as a true mouse, but is now categorized differently (though it is a rodent). Another potential choice is the a mouse-like hamster found in the Zagros Mountains in Iran, which is in the same superfamily (Muroidea) as the true mouse, but not the same family.
