Compare lists in Prolog -


i need compare list fact includes list. example have 2 facts: 

level1(toothed_whale,[1,2]). level1(baleen_whale,[2,1]).

i want create predicate compares these facts list of creation. if compare level1 list [1,2] want function return toothed_whale. if compare level1 list [2,1] should return baleen_whale. how do this?

i'm not sure you're asking, can execute simple queries.

for instance:

2 ?- level1(x,[1,2]). x = toothed_whale .  3 ?- level1(x,[2,1]). x = baleen_whale.

is you're asking?
