There is only three things that get me about the Purple Ludroth.

1. They prefer shallow water over deep water, unlike the normal one(Thats why we don't see them swim).

2. Their believed to be nomads wandering from place to place like Deviljho.

3. Their skin is said to be paler than a normal Royal Ludroth.
