Alpha Phi Omega has no mascot, but has several symbols:
Jewel: Diamond
Tree: Sturdy Oak
Flower: Forget Me Not
Bird: Golden Eagle
The last three are sometimes refered to as our "Living Symbols".
While we don't have a national mascot, this does not stop chapters, sections or regions from having them. Ask APOers from Region III about Frank the Friendship Frog. Or visit his website:

Hope this helps
