The three-eyed fish from The Simpsons was an Argentine - Polidicks

[QUOTE=BCell;33033254]If so, why couldn't humans evolve with four arms instead of two?[/QUOTE] Because there's no way that a chance mutation could alter physiology that's been common to vertebrates for the past 200 million years (that is having the typical vertebrate skeleton of four limbs). Third eyes are another story. Many animals have them, including some fish and especially amphibians - though only ever for the function of detecting movement or light. Third eyes are also found in humans and other vertebrates as the vestigial pineal gland. [url]http://en.wikipedia.org/wiki/Parietal_eye[/url]

[QUOTE=Hidole555;33020213]For some reason it reminds me of the Varren from Mass Effect. [IMG]http://images.wikia.com/masseffect/images/f/f5/Varren.png[/IMG][/QUOTE] Which are also called "Fishdogs" in the game.

If you press the middle of your forehead and feel a bump there, you've been spending too much time around radiation.

[QUOTE=Swebonny;33021466]It got fucked up so perfectly that a third eye appeared. I wish I lived in nuclear waste.[/QUOTE] [IMG]http://img834.imageshack.us/img834/8419/nuebonny.png[/IMG]

I love my country.

You're all morons, Mutations happen in fish all the time, Take a look at Platies and common Goldfish, they often mutate into having bags under their eyes, big bugeyes, or even an extra fin or NO dorsal fin at all.

Most species of fancy goldfish, guppies, and other fancy fish are "made" using selective breeding. Whether or not this is caused by radiation I think needs further genetic investigation as there have been weird mutations in fish in the past, like the albino cyclopse bullshark posted above. They don't usually live long though, like many other genetic fuck-ups. That fish looks pretty well aged though so who knows.

It looks kinda cute Like all :D

[QUOTE=Electrocuter;33031384]For a mutation that eye is amazingly well centered on it's head.[/QUOTE] As I said before, it most probably just took the place of the genetic pre-placement of the parietal eye/pineal gland, which is centered on the top of the head. [QUOTE=Catesby;33032663]That argument is wrong. Species can have unique or very rare adaptations, the idea that just because allot of species don't have something no species can is totally wrong. For instance; * Humans are unusually intelligent and can finely manipulate objects. * Spiders can squirt a web that is stronger than it's weight in steel * Venus fly traps attract flies and digest them * Chameleons change their colour for camouflage How can you possibly say that having 3 eyes has no evolutionary advantage. Here are a few that might effect this fish. * Having 3 eyes gives the fish a large field of view to escape from predators as well as the depth perception necessary for hunting * The fish is adapted to swimming in water which damages its eyes, it has an additional eye so it can function with 2 eyes while one is closed healing. * The third eye has a large amount of rods and is used to detect the shadow of a predator when the fish is in shallow water. In conclusion, your argument is wrong.[/QUOTE] This is all assuming the eye works as it should, and in synchronization with the other eyes, which it probably doesn't. As I said before, for a vertebrate or similar animal to have 3 or more working eyes, it needs a dramatic restructuring of its brain, which this fish has not gotten. The positioning of the eye might also mess up the visual field as it isn't synchronously placed with the other two eyes in a straight line, but rather like a triangle. Finally, a third eye would take up a large amount of energy. The visual cortex is the area that uses the most energy in the brain, and the brain is the most energy-hungry organ in our bodies. It all boils down to balance in evolution. Yes, there are advantages with 3 or more eyes, but there are disadvantages too, and if the advantages would fair-outweigh the disadvantages then the genetic group with 3 or more eyes would survive much easier and we'd see a lot more animals today with that trait. Besides, evolution doesn't happen overnight, and our brains have been wired for at least 300-500 million years to support two eyes only. In order to have 3 eyes we'd need to slowly adapt our brains in that direction first, which might even be impossible, or evolutionary disadvantageous while we're "on the way". Most likely if any species is going to have 3 eyes, it's going to evolve its brain from scratch (or at an early stadium, like where we separated from insects).
