glowing eyes

[Charles17]

i like the white glowing eyes better than the new yellow glowing eyes...

i like the white glowing eyes better than the new yellow glowing eyes...

I'm not sure which I like myself, but is there any scientific biological reason/theory for the glowing eyes in the first place?

[Charles17]

lol... i think it makes more sense that itd be yellow or redish... cuz if u make a light behind flesh, the color of the light will be influenced by the color of the tissues... but white looks better i think... lol

[Eoin]

since the goa'uld dont have any gold objects around them (which reflected the yellow colour to their eyes when they glowed) their eyes now glow white

Yes, I know I'm funny like that, I just have to have an explanation for everything! So I came up with one myself to justify the light behind the eyes. So if your little kid asks you, you can tell him this : The Goa'uld originally started living like fish in lakes and seas before they could take humans as hosts. There are many bodies of water, where the water is sooo deep that no light can penetrate it, it is in these depths that fish like the hatchet and lantern fish who have light-producing organs live. Well, the deep sea was part of the goa'ulds habitat too, so they needed light-producing organs as well, just like the fish. When they started taking human hosts, the lights came in real handy for finding just the right place to stick their heads when they got inside somebody's brain. That is why the light usually goes on when somebody has just been taken as a host. How were the little goa'ulds smart enough to know where to stick there heads in the first place? A little trial and error, and don't forget instinct.
Then again, maybe you shouldn't tell a little kid this.

I thought of the same theory too a while ago, it makes alot of sense. As for diff colours, I suppose it depends on the diff genetic codes each goa'uld can have for that. I prefer gold even through glowing red eyes would suit them better as they are evil, I did used to wonder why that wasn't so!! Don't know about yellow as haven't seen S9 but Daniel's wife's goa'uld flashed gold so that's not new.Still I don't get how the light from the glowing organs or eyes that a goa'uld might have makes its way to the host's eyes, prehaps by an electical signal along the nerve that leads to the eyes somehow.

Here's a copy of something I've written before. I feel I have a viable explanation about the 'glowing eyes' thing...

Goa'uld Biology: A Goa'uld symbiote is like a living Bio-pharmecutical. It is capable of creating a nearly endless number of chemical combinations that it uses to control and heal its host. There is also something of an electrical-eel sort of nature to the symbiote. They actually require a small electric field to survive as larvae. It is however, much more specialized, specifically being used to control the brain functions of a host, along with certain chemical combinations. As far as I know, a symbiote couldn't actually shock anyone that was holding... unless it bit them... that might work. I say that, because I suspect the biological hardware for 'plugging' into a host brain is located in its head, and engaged through its mouth. A symbiote essentially wraps itself around the spinal column, reaching up into the brain with its head. The host is capable of fighting the symbiote for motor control, but usually looses after the host expends more effort for control. This usually requires an extra 'surge' of electrical energy through the host brain that often occurs when a Goa'uld is excited, or frustrated. The electrical 'surge' in the host brain actually produces visible light. Most of that light is unseen because the host brain is encased inside its skull, which is not transparent. However, the eye sockets of the brain are not covered by sufficent material to trap the light within the skull. So when a Goa'uld is excited or angry, visible light is sometimes seen to come from the eyes of the host. This light, is simply a by-product of the symbiotes method of controlling the host.

Goa'uld sexuality: Goa'uld are asexual. They have no gender, with the exception of special 'queens' that are capable of breeding new Goa'uld symbiotes. If a symbiote were able to become a queen, as part of a life-cycle, then the Tok'ra wouldn't be in such straights right now. However, the symbiotes do appreciate sexuality and one of the reasons for them choosing humans is because they find humans sex to be particularly enjoyable as compared to other alien races. As someone has already stated, they also picked humans because they are easy to repair... but overall the reason is because that humans are very comfortable host to have. Easy to control, easy to repair, attractive (sometimes... ), relatively strong, very capable manipulator (in terms of interacting with the physical world), and capable of very enjoyable physical sensations... (i.e.- sex)

Goa'uld memory: The Goa'uld memory is genetic based. All their memories get converted into genetic sequences. This is how a queen is able to pass her knowledge on to her larvae. She may choose to pass on all her knowledge, or she may choose to with-hold some knowledge. It is possible for them to pass on their genetic memory to their host offspring as well, but this is taboo, and very dangerous to the species in general. Apophis did this on purpose once, but humans on Earth did it once too, artificially. Neither case ended well for those doing the manipulating. Only Shifu (Apophis' child) escaped his fate, and that was only because Oma Desala stepped in to help him.

Goa'uld Brain-function: It is very likely that Goa'uld have very tight synapse connections, allowing them to have a greater degree of intelligence given their small brain size. However, it might be observed, that a symbiote does not reach its full potential until taking a host. A symbiote does not have a gender, but it does take on a 'gender-role' after it takes a host. Usually they prefer to take a host of similiar gender, but sometimes will make an exception, particularly if they don't have a choice. The Goa'uld's higher brain functions are conducted in the host brain, upon implantation... this isn't always an easy task, especially if the host has a strong mind already. This is the reason it sometimes takes time for the blending to be completed, some host are more difficult to blend with than others. This is also the reason that the symbiote and host sometimes share emotional feelings and always share memories and knowledge. The symbiote is intelligent in its native form, but is incapable of achieving anything of real use until it has taken a host to help it manipulate the world around it. After taking a host, a Goa'uld is as much influenced by its host, as the host is by it. Of course, the symbiote takes the dominate position of the blending, but the attitudes, and characteristics of a Goa'uld are largely influenced by the host as well. Depending upon the host, those influences will vary from symbiote to symbiote.

Thanks, Seastallion. Some people would not care to read this but for me it increases the illusion of realism, and that just makes watching Stargate or anything else that much more enjoyable if you know it makes sense. And why not give you some green for a post you made awhile ago? I think that took a little work anyway.

[deathbed1983]

Seastallion what you wrote actually seems to make alot of sense you get some green from me...lol

Ok. Hey. I'll play along.
Along time ago the symbiotes used to get their basic bulding block molecules of their form of "luceferin" from the phytoplankton in the ocean that they inhabited. They ingested these buiilding blocks and converted them to their own version and it was stored in two sets of photophores near the head of their body (those are tiny complex light organs that can be rotated). Since they started parasiting (if that's the word to use) humans, and their diet changed to nutrients derived from humans, they had to come up with a different version of "luceferin" to incorporate into their photophores. One that does not emit any "damaging to the human eye" blue light.

The symbiote is able to make the human host grow an additional alternative route for the humans optical nerve, which is solely used by the symbiote. It leads over to where the symbiote is. It is connected in tissue, but not in nerve path form until a light signal is produced by the symbiotes photophores directed at this channel.

The symbiote is able to grow an additional optical nerve channel for itself that is connected to its regular one which it can expose and then attach to the humans extra nerve channel. On the symbiote side it remains connected as it serves an additional purpose which is ......the symbiote uses its path as a means to monitor the condition of the eyes and maintain a very high rate of activity for the humans "retinal pigmented epithelium cells" which are the nursemaids of the photoreceptors in the human eye. It also uses it to send plant pigments/molecules such as Zeaxanthin and lutein (which are eye fat antioxidants so to speak) and ones that we still don't know about yet to the retina.

Bottom line they still need the photophores in order to trigger the optical nerve in the human host to switch over to the path which leads into the symbiotes optical nerve input which the symbiote is able to grow. There is a layer of porphyrin nanotubes that run along the outside portion of this "extra optical nerve channel" that the symbiote has made the human grow. The symbiote easily assembles the porphyrin nanotubes by using the porphyrins that are already in human blood and diet (heme and chlorophyllin).

When the symbiote emits light from its own photophores the whole path of porphyrins flouresce and stay lit for a short amount of time as a byproduct. The light is a switching mechanism. Maybe some symbiotes don't give a crap about blue light and just use some less energy intensive luceferin which emits blue light. Possibly the alternative path is able to be made very quickly when forced to and the symbiote keeps a ready supply of antioxidants and porphyrins on hand knowing this. You are just seeing backlighting of this which is passing through the various tissues behind the eye. The "switch off" mechanism does not need the light trigger through the porphyrin nanotube path but only an electrical impulse sent through the center of the nerve channel to close the path on the other end.

Howya like me now?

In the real world, there's a parasite known as Sacculina Carcini. It settles in a crab's underside and grows, forming a bulge in its shell and sprouting a set of rootlike tendrils, which spread throughout the crab's body, even wrapping around its eyestalks. Field biologists identify an infested crab by their green florescent glowing eyes.

So there's definitely a biological basis for the ficticious Goa'uld.

How cool..! ...and weird. Here's some green for that very cool and obscure bit of trivia..!

thats Awesome

The creators of SG-1 probably like glowing eyes. First the Goa'uld and than the Ori. But it is cool.

[Uber]

I'm intrigued by the colors too...for instance, Heru'ur's eyes glowed red in Thor's Chariot...
