The tuna is a sleek and streamlined fish, adapted for speed. It has two closely spaced dorsal fins on its back; the first being "depressible” it can be laid down, flush, in a groove that runs along its back. Seven to 10 yellow finlets run from the dorsal fins to the tail, which is lunate curved like a crescent moon and tapered to pointy tips. The caudal peduncle, to which the tail is attached, is quite thin, with three stabilizing horizontal keels on each side. The tuna's dorsal sides is generally a metallic dark blue, while the ventral side, or underside, is silvery or whitish, for camouflage.

Tuna are a group of salt water fish from the family Scombridae, particularly of the genus Thunnus. Tuna are fast swimmers, and some species are capable of speeds of 70 km/h (43 mph). Unlike most fish, which have white flesh, the muscle tissue of tuna ranges from pink to dark red. The red coloration derives from myoglobin, an oxygen-binding molecule, which tuna express in quantities far higher than most other fish. Some larger tuna species, such as bluefin tuna, display some warm-blooded adaptations, and can raise their body temperatures above water temperatures by means of muscular activity. This enables them to survive in cooler waters and to inhabit a wider range of ocean environments than other types of fish.

Archer Salutes Limbaugh
At the risk of annoying my fellow progressives, I wish Rush Limbaugh a speedy return to the EIB network, even though the EIB Network doesn't exist--Limbaugh made it up, along with nearly everything else he broadcasts, such as How the Sidwell Friends School Taught Chelsea Clinton To Hate White People.
While you may actually doubt that the quiet Quaker school in Friendship Heights ever taught Chelsea any such thing, it is an impressive fact that millions of dittoheads don't doubt it at all, simply because Rush Limbaugh said it. This is a singular and noteworthy achievement. Limbaugh is a magician. Into the hat goes a factory belching cyanide and arsenic, and--SHAZAM!--out of the hat comes a HUNDRED DOLLAR BILL. And he gives it to you!
You're rich, by God!
You have a hundred smackers!
And those people squawking about cyanide--THEY WANT TO TAKE IT AWAY!
Gaze in awe.
We have to take a break, folks.
It's the voice, mostly. Limbaugh croons. His baritone can swoop and dive and do backflips. Next to him, Dan Rather sounds like an actuary. Others compete: Laura Ingraham's rough baritone can charm, as can Sean Hannity's toy drum. But Limbaugh is of a rarer order. You'd pay good money to hear him lie, just as you'd pay to hear Pavarotti sing. Limbaugh is the Figaro of the fib, the Don Giovanni of deceit. Catching his act is one of America's guilty pleasures. I wish him well, and I hope he beats the drug rap.

"Tuna Fish News" is named in honor of the late Laura Nyro, who published her immortal "Stoned Soul Picnic" and "Eli's Comin' " in the late 1960's and early 1970's under the imprimatur of Tuna Fish Music. So far as I know, Laura Nyro's masterpieces are known only to Boomers, which just proves that we are actually the greatest generation, or at least the best-laid.
