Answer:
What fish came first?
John Lennon sang about being this toothy creature.
It is a big and bulky mammal, And has a trunk just like a tree. Will store water in its nose, Which is long and like a hose.
It's black and every time it speaks it says its name.
It's small but larger than a bee, And agile as a flea. It humms but does not buzz, And it's not covered with fuzz. It is a small collector, Of juicy flower nectar.
I hold two meanings. With one I may be broken, with the other I hold on. What am I?
