In Biology we always learned that the symbiotic relationship between the remora and the shark was an examle of COMMENSALISM, where one animal (remora hitched a free ride) benefitted and the other (shark) was not harmed.
It seems like you are now saying that the remora-shark symbiotic relationship is now MUTUALISM. Is this correct?

Could be so.
As a high school teacher I am reminded of how many symbiosis
nurtured students attached themselves to me, and I don't think
it was hero worship. Hard to hurt their feelings, but they
needed to get a life. I called them barnacle-buddies.

By the way, welcome to the forum, Big Joe. Hope you enjoy
your stay.

Although I do not very well understand who the "you" is in your first post of a new thread ( welcome ) this Wikipedia link gives quite some information on the remora - shark issue.
Some think commensalism others mutualism,(don't wanna be a remora).

as we have seen much of lately, many seem to think that they are posting directly to Anu (or his minions) when they post here for the first time.

Wouldn't it take nine more of you to make a minion?

Neat. Now I know how to do this.

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?
