Thanks, Ron. I got a kick out of reading your note! YES..MIB's do exist. Did you get a chance to read my story about the 'visitor' I met at MacDill? He had 2 sets of eyelids...honestly...reptilian! I about s... my pants when I saw his eyes...never forget them!
Well....You probably have a pretty good idea about me by now, and I said: "C'mon Captain, we all saw that thing last night, and it wasn't any kind of aircraft we've ever seen. What was it...and who's"? We all were looking directly at him, then curiously, like something’s not right with this guy, like he didn't seem to be alive. Kind of a waxy face, almost plastic or mannequin like and strange light green color eyes and wearing black gloves in 95 degree heat in a full dress uniform with no name tag. And not sweating!
He said: "I don't know what you're talking about, now get back to your units"! After what we saw the night before and the crap from the AP's, I was getting pissed. And when I saw he wasn't armed, when everybody we saw was, I wanted answers. I still had my M-16 in my hands. I made a kind of threatening move by wrapping my hand around the grip and trigger and said point blank: "Why are you wearing black leather gloves in this heat and not sweating"?
He didn't answer. I clicked off the safety. It seemed like if you were a mile away, you would have heard that click. He twitched at this and looked at the weapon then me. He knew I wasn't impressed with his rank. Nobody moved. Like time stopped. It was uncannily quiet. He was about five feet in front of me. And I thought: "If he makes a move towards me, I'm going to cut him in half".
He took two slow steps backwards and turned to head back to his jeep. First, he would have jumped down my throat for not saying "Sir" if he was a Captain. Then I would have been standing before a court martial for handling a weapon in a threatening manner. Third, he started back to his jeep (with no driver) and no response.
I was going to stop him but the MS was really freaked out by this time and ran up to me and said: "Are you crazy? What are you doing"?
I protested and said: "Sarge, this guy's an impostor, can't you see that? Everybody else might be dead"!
He said: "You may be right but I'll find out what's going on when we get back. Don't take the chance of a court martial for threatening an officer"!
I remember say something like: "I already did that and if he's an officer, then I'm an alien"! The "Captain" heard that and turned back and looked at me with black eyes! It sent a shivering chill up my spine upon seeing this and said: "Did you see that? Look at him! His eyes are black now"!
I started to raise my weapon at him and tell him to stop and the MS got in front of me and said: "Stand down soldier, that's an order"!
As the Captain drove off back towards the training area I told the MS: "We'll never know now, that's the last time we'll see him and you aren't going to find out anything when we get back and know it".
He said: "I know, but we saw something special and can't repeat it, can we? Who would believe us? And someone would stop us one way or another. And if I let you shoot him, and he is what he looks like, where would we be then? And what makes you think he didn't have a weapon? Because you couldn't see one? He may have had something that could vaporize all of us, the size of a lighter"!

The Sagalla caecilian is found in just one location – the Sagalla Hill in the Taita Hills of south-east Kenya – in an area less than half the size of Manhattan Island. This species spends most of its life below ground, and is adapted for this burrowing lifestyle by having eyes protected by skin, a strong bony head for pushing through the soil, and sensory tentacles on either side of their head to detect the chemical signals of its prey. Having laid her eggs, the female Sagalla caecilian will guard these until they hatch, and may even feed the newly hatched young on her own skin like its close relative, the Taita African caecilian.
Gallant and his expedition partner, veterinarian Dr Chris Harvey-Clark, had both been intrigued for years by the occasional news reports of Canadian anglers landing an unexpectedly large catch while ice-fishing - a Greenland shark (Somniosus microcephalus). The Greenland shark belongs to the family of sleeper sharks, so named due to their sluggish behaviour, and is related to dogfish sharks. Preferring frigid waters from below freezing to about 12°C, the Greenland shark inhabits the depths of the Atlantic to at least 2,200m, and swims under the polar ice cap. Its slow swimming pace, the minimal resistance it puts up when captured, and inability to raise its body temperature above that of the icy waters suggests that it has a particularly low metabolic rate, and raises the question of how the species captures enough food to grow to lengths of up to 7.3m - larger than a great white shark. Part of the answer may be an extremely slow growth rate - about 0.5cm a year, according to one study - leading to estimates that a 7m specimen could be more than 200 years old, making Greenland sharks possibly the longest-lived vertebrates on the planet.
Greenland shark meat contains high levels of an ammonia-like compound, so is toxic if eaten fresh. The fermented flesh is considered a delicacy in Iceland. The chemical that renders the flesh toxic apparently functions as an antifreeze/preservative to protect the shark's body from freezing temperatures and crushing pressures (up to 9,700kg per sq cm) at the great depths they inhabit.
The female mite known as Histiostoma murchiei creates her own husband from scratch. She lays eggs that turn into adults without needing to be fertilised. The mother then copulates with her sons within three of four days of laying the eggs, after which the sons die rather quickly.
Octopuses are highly intelligent, likely more so than any other order of invertebrates. The exact extent of their intelligence and learning capability is much debated among biologists, but maze and problem-solving experiments have shown that they do have both short- and long-term memory. Their short lifespans limit the amount they can ultimately learn. There has been much speculation to the effect that almost all octopus behaviors are independently learned rather than instinct-based, although this remains largely unproven. They learn almost no behaviors from their parents, with whom young octopuses have very little contact. An octopus opening a container with a screw cap An octopus has a highly complex nervous system, only part of which is localized in its brain. Two-thirds of an octopus's neurons are found in the nerve cords of its arms, which have a remarkable amount of autonomy. Octopus arms show a wide variety of complex reflex actions arising on at least three different levels of the nervous system. Some octopuses, such as the Mimic Octopus, will move their arms in ways that emulate the movements of other sea creatures.
Land planarians devour earthworms, slugs, insect larvae, and are cannibalistic. Prey are located by chemoreceptors located in a single ciliated pit under the head or in a ciliated ventral groove. Struggling prey are held to the substrate and entangled in slimy secretions from the planarian. The pharynx is protruded from the mouth and into the prey. Food is reduced to small particles prior to entering the gastrovascular cavity. The food particles are taken by epithelial cells in amoeboid fashion and formed into food vacuoles. Planaria store food in digestive epithelium and can survive many weeks shrinking slowly in size without feeding. They are capable of utilizing their own tissues such as reproductive tissue for food when reserves are exhausted.
It won’t win any beauty contests, but in terms of talent, the weird-looking star-nosed mole is the one to beat. The little mole, scientifically known as Condylura cristata, commonly lives in the wetlands and marshes of the eastern United States. As its name implies, it has a star for a nose — specifically, a snout made up of 22 fleshy tentacles, that form a fleshy, circular star. And with that star, says biologist Kenneth Catania of Vanderbilt University, the little mole can do some remarkable things. For example, Catania, who has been studying the unusual mole since his graduate student days at the University of California at San Diego, recently discovered that star-nosed moles have the odd habit of blowing bubbles underwater through their nostrils. It’s not mere play. Using a high-speed camera, Catania filmed the moles as they created the bubbles — at a rate of between 5 and 10 bubbles per second, or about the same speed at which other rodents sniff — and found that most of the bubbles are immediately sucked back into the nose. He also discovered that the moles aim their bubbles at specific targets; they’ll blow out a bubble to touch the surface of an object, such as a piece of an earthworm (a star-nosed mole delicacy) or a small fish. “When these bubbles come into contact with an object, it is almost inevitable that odorant molecules” — those that impart smell — “will mix with the air and be drawn into the nose when the bubble is inhaled,” Catania says. That means, he says, that the mole uses the bubbles to smell. The finding came as a big surprise to Catania and other scientists, because mammals weren’t thought to be able to smell underwater at all, much less smell by blowing bubbles.

Dunno... you got a silicon based life form I can study?

I think the aliens would be fish-like. Would an alien making the investment to travel all the way to another planet not choose a world like their own? I'm sure that ET would be able to tell that the earth is mostly covered with water and would reasonably conclude that the inhabitants were aquatic.

what do you think "carbon based" refers to, genius?
Diatoms in both fresh and salt water extract silica from the water to use as a component of their cell walls. Likewise, some holoplanktonic protozoa (Radiolaria), some sponges, and some plants (leaf phytoliths) use silicon as a structural material. Silicon is known to be required by chicks and rats for growth and skeletal development.
Silicon is in human connective tissues, bones, teeth, skin, eyes, glands and organs. It is a major constituent of collagen which helps keep our skin elastic, and it helps calcium in maintaining bone strength.
Carbon forms the backbone of biology for all life on Earth. Complex molecules are made up of carbon bonded with other elements, especially oxygen, hydrogen and nitrogen. It is these elements that living organisms need, among others, and carbon is able to bond with all of these because of its four valence electrons.
Characteristics of carbon as a basis for life
The two most important characteristics of carbon as a basis for the chemistry of life are that it has four valence bonds and that the energy required to make or break a bond is just at an appropriate level for building molecules which are not only stable but also reactive.
The fact that carbon atoms bond readily to other carbon atoms allows for the building of arbitrarily long and complex molecules.
There are not many other elements which appear to be even promising candidates for supporting life-like behavior, but the most frequent alternative suggested is silicon. This is in the same group in the Periodic Table of elements and therefore also has four valence bonds. It also bonds to itself, but generally in the form of crystal lattices, less amenable to a complete source of life, rather than long chains. However, its compounds are generally highly stable and do not support the ability to readily re-combine in different permutations in a manner that would plausibly support life-like processes.
This speculation of a life based on the chemistry of silicon is clearly distinct from "silicon-based life" in the above sense of artificial intelligence based on electronic processes utilizing silicon integrated circuits.
