Catfish barbels detect prey by sensing pH changes

If one looks at the links I posted - http://en.wikipedia.org/wiki/Lateral_line - uses shark as an example. Yes, sharks do have them. They also have more of the sensory organs of the related capacity around their heads too.

The second article is somewhat misleading. It says some of the neuromasts have been evolutionarily modified but should have stated not all of them. Sharks still posses a real "lateral line" if you should say. Just look at a shark and it's usually where the white under belly turns I to the darker top portion of the shark. Here's a pic of a little blacktip recently caught the lateral line is right ontop of the flash mark below his dorsal fin.

Cool, then I humbly accept that I was in error and take it with the dignity a Mod should. lol

And to you too.

Dignity is way overrated. Humbleness is way underrated...

Hey, I am too, sadly, for the most part a "forum and google researcher" when it comes to our hobby. We all need to educate ourselves on fish anatomy and physiology somehow...
