Since they eat like slime-pigs
This quote should be preserved for posterity somehow.
As a taxidermist that skins out and mounts his share of "slime pigs" I can assure you the name is well warranted. They have plenty of slime on their bodies and the skin head and fins have to be soaked in paint thinner overnight to be sure to rid them of any oils.
Don't get me wrong I think they are a neat species.
