dolphin is 5000 - 50,000, orca is 50,000 to 500,000 and a whale is 500,000+

I think you have above and below the wrong way around, minnow is above 500 and below 5000

In not sure about plankton and redfish, it could be plankton 0-50 and redfish 50-500

Glad you have join in. the best way is up :-)
