The praise the Lord list is all inclusive even though not everyone on the list gets along. Wild animals eat cattle, kings make war on princes, fire and hail and wind do damage to fruit trees and of course sea monsters are not called monsters for being friendly to sailors. I don’t think the point is that if the all inclusive list spent more time praising the Lord they would spend less time preying on one another. You can over think a psalm in the same way that the marriage of melody and lyric loses something when the words of a song are over analyzed. So let’s just say the symphony of the all inclusive praise psalm is the song of everything all at once exalting the name of the Lord which is a joyful noise to the Lord (even if the sound a sea monster might terrify us).
