[Google sheet] Check if values in list exists in another list and show them in range

hi,

i have 2 ranges:

First ("A1:A3"):
Cat,
Dog,
Elephant

Second ("B1:B3"):
Cat,
Dog

and in "C1" i want to get Elephant (it exists only in first list and not exists in second).
How can i do this in google sheet?
