If you were transformed into an animal, you'd be a:
Many people picked mammals:
- polar bear
 - flying squirrel
 - dolphin (x2)
 - wolf
 - panda
 - otter
 - capybara
 - sloth
 - dog (x3)
 - human (x3)
 - bushbaby
 - [own first name] (x3)
 
The surprising-to-me frontrunning category was birds. Birds!
- penguin (x3)
 - bald eagle
 - duck
 - eagle
 - owl
 - bird (x2)
 - Big Bird
 
Kudos for picking "birds", but the specificity of mammals was lacking here.
- shark (x2)
 - stable matching
 - meal
 - dragon
 
I'm not sure that "stable matching" is an animal, so there's a type error there. Who wants to be a meal? At least one student in my class!
This post's theme word is infundibuliform (adj), "funnel-shaped." I'd be an infundibuliform sponge; it seems meditative.
