Wailmer evolves at level 40 into Wailord
You can catch level 40-55 Wailords with the super rod at Route 223 and Route 230, but the chance of a landing Wailord on your super rod is very rare, at 5%. Level 30-40 Wailmers are much more common, at 30%. To save time, catch a Wailmer with a super rod and train it to level 40 and it will evolve into a Wailord.
Wailmers evolve into Wailords.
First go to the Pacifidlog town (Where Wailmers are at high LEVEL), Next, use a super rod to catch a LvL 34,35,36 or if lucky a LvL 36 Wailmer, Then feed it few rare candies or train it to level 40 and it will evolve into a Wailord.
If you want to avoid them, try using a repel or try and avoid going to where the Wailmers are.
