It seems like you are now saying that the remora-shark symbiotic relationship is now MUTUALISM. Is this correct?

Bio Joe, I, too, am a newbie. The only biology I studied formally took place 55 years ago. I still know though that the head bone connected to the neck bone have parts that are called a frontal, a temporal, and an occipital.

But, (there's a conjunction that is beginning a sentence [that's relative to another list on this forum]) don't sharks benefit from the presence remoras? Don't remoras serve as a kind of vacuum cleaner for a shark's skin?
