They call the people who have LOTS of STEEM power and stake here Whales. The smaller folks (in terms of stake) are referred to as dolphins, redfish, minnows and such. Up to 500SP, the term apparently is plankton or maybe krill?

Anyhow it is an ocean theme and I just crossed the magic 500 SP mark (you can see that if you look in my wallet) so that makes me officially a minnow!
