Chris,
Southern Hemisphere lampreys don't behave like most of the North American
species. Adults of both of the two parasitic Australian lampreys (Geotria
australis and Mordacia mordax) use the denticles on the tongue to shear off
chunks of flesh, and don't feed just on fluids like Petromyzon,
Ichthyomyzon, etc. Geotria is supposedly almost exclusively a flesh-feeder.
They're fast, too. My boss collected some last year, and in the process of
taking some pictures of a large adult, it attached to his thumb and took a
large chunk of tissue out of it (I wish somebody would have gotten video of
this...)!
cheers,
Dave
