Interesting find Cecil.
Oh and by the way I thought you exhibited enormous restraint in not comparing a Nine-Spined Stickleback to a politician based upon this quote:
"These fish are obviously not at all closely related to humans, yet they have this human ability to only copy when the pay off is better than their own."
I read the article on Bluegill too.It seems if your BG get stressed out,your water is polluted.
If 75% of the sticklebacks can learn from the experiences of others, that may surpass human learning abilities. Most of us have to pee on the electric fence ourself.

And some of us out there fulfill the definition of insanity quite well: repeating something over and over again and and expecting to get different results.
Speaking of sculpins I got a lot of ribbing in a fish identification class in college. Seems there is ugly sculpin with the scientific name Cottus Bairdi.
Theo, that is pretty hilarious. And I claim the fifth as far as whether said wisdom applies to myself.

Cottus bairdi, the mottled sculpin... Probably the most common sculpin in North America. I have caught many a trout using them as live bait. Cool little aquarium fish if if you can keep the water cold enough for them!

It lost some of it's coolness preserved in formaldehyde and repeatedly pulled out for examination!
I know you were young and foolish then, Cecil, but keeping it in formaldehyde and repeatedly pulling it out is no way to treat your mottled sculpin.
If I'm not mistaken that's a misdemeanor in California.
Same thing happened to Condello. Perhaps someday, you guys will heed my advice.

I just got a sudden groin pain reading that. Now what idiot would do something like that, I wonder

It's a good thing you are the moderator and not me.
On a serious note I guess schools no longer use formaldehyde as it's a proven carcinogen. I once accidentally ingested some Carbon Tetrachloride through a pipette in a college chemistry class. I was told that was a big no no.
Cecil,
We use formaldehyde here at my school. One thing you don't want to do is get it in a cut.

There is so much that I could do with this information, I just don't know quite where to start.
Brettski?
Theo?
Bueller?
Anyone?
I took 3 quarters of Chemistry my Freshman year of college, with a 4 hour lab every Wednesday morning. One of our earliest labs involved testing an unknown for the presence of alcohols, using Acetyl Chroride. In the presence of alcohol, Acetyl Chloride "gives off heat and vapor" (per the text).
After testing my sample, I had 20-30 ml of Acetyl Chloride left over to get rid off. I knew better than to just pour in down the drain in a sink, so I set it in the sink and started to dilute it with water first. It turns out that in the presence of water, Acetyl Chloride gives off lots of heat and vapor. Lots and lots and lots.
I shut off the water quickly and after the small Acetyl Chloride geyser in the sink stopped erupting, I looked around. No one had noticed! I took the leftover Acetyl Chloride back to the original container and decided I would just pour it back in there.
I must have had more water than Acetyl Chloride in the leftover sample by then, because I got an even bigger geyser erupting in the big container we all had obtained our Acetyl Chloride from. I closed the vent hood door to keep the geyser contained and quickly walked away. I remained nonchalant, even as I heard a loud "WHUMP" noise coming from the vent hood. Glanced around the lab one more time; STILL no one had apparently noticed. Whew!
Eight months later we had our last Freshman Chem lab. Before leaving, we all said farewell to wise, kindly Mrs. Loats, who had been our lab instructor for all three quarters. As she in turn said goodbye to each of us, she said how amazing it had been that I had made it through three quarters of labs without blowing anything up or killing anyone.
Cecil,

Really? I heard there was a noncarcinogenic substitute now but I guess I heard wrong.
Theo,
I'm glad you weren't on my crew when I was a weapons specialist in the ANG loading bombs and missiles!
Just kidding of course. I did have a guy on my crew doing a make up day when I wasn't there, that loaded BDU's and didn't tell the other crewman in the cockpit about it when he did an electrical check. Needless to say one or more BDU's dropped on the tarmac with a big bang. Fortunately for those of you that don't know a BDU is a (Bomb Dummy Unit.)There is cartridge behind them that is kind of like shotgun shell without the pellets that disengages the BDU when it receives an electrical charge. Poor guy got a drug test every hour on the hour for days.
We had another guy that was so dangerous we all swore if we went to war we have to take him out behind the barracks and shoot him so he wouldn't wipe us out. I think he smoked too much wacky tabbacy in the 60's and it did brain damage.

Try drinking beer that has formaldehyde in it. A few overseas beers use it. The first was is tough, after that you get used to it. The hangovers from them are a whole different story.
