I can't know what's the difference between the sentences below.

1) This tiny creature has the distinction of being the first fly to be declared an endangered species in the U.S

2) This tiny creature has the distinction of being the first fly which is declared an endangered species in the U.S

Could you tell me the difference ?

They are all same? or they are different?
