Minnows
These are the newbie in the community. Yes, they are lowest earner but everyone here started from the bottom. They have the lowest ability to influence a post since their voting usually cost $.01. It takes time and effort to post, resteem and a lot of following to do.
Dolphin
Dolphin don't have as much power as whale. I'm not sure how much SP for you to be consider as a dolphin.
Whale
Whales are market changer in the market. If your post were noticed by a whale its gonna be lucky day. These stemmers whose SP is more than 50,000 and will have big effect on your post
