  • Come to think of it, blue whales do look a little mousy.

    Mussels, not so much.

  • It's interesting to note that the blue whale and the house mouse share the specific name musculus (binomial names are respectively Balænoptera musculus and Mus musculus). Both names were chosen by Linnæus (Carl von Linné) in the XVIII century.

    The word is a diminutive of Latin mus (mouse), so there is no need for explanation for using it for the house mouse. But what about blue whales?

    The explanation relies on the fact that, in Latin, musculus also means muscle; and this is the meaning it has in the blue whale's scientific name.

    Apparently, in the past, ...the shape and movement of some muscles (notably biceps) were thought to resemble mice... (From: Online Etymology Dictionary).

    What is also interesting is that the same double meaning/common root is present in other languages: Greek, Armenian, German, Arabic.
