Question

and not " restés ", "On" in this question implies that "we" the humans, which is plural.

Chris Wirt · Accepted Answer

Yes, but unless it is a personal "we" (as in me, my wife and the kids) you don't use the plural. 
 
On est allés en vacances. -- We went on vacation. 
On est allé à la lune. -- We went to the moon (we=humanity. )
 
-- Chis (not a native speaker).

I believe I understand the general principle. However, in the sentence given by stephen it seems contradictory to me that it then goes on with a plural "des prédateurs". To me this indicates that the "on" is a real plural and the participle should be "restés".

Chris Wirt · Answer

no matter, Almut. The impersonal "on" will always take the participle in singular to distinguish it from the more personal "on" meaning "we".
