'Size Matters' in Sexual Attraction for Fish (Newsmax)
Size matters in the science of sexual attraction - especially if you are a fish.
Scientists at the Universities of Exeter and Glasgow have found that female green swordtail fish mature more rapidly if they spot a male with a big tail.
Likewise young males retard their sexual development for several months if they spot a better-endowed male, waiting for there to be less competition in the mating game.
"This is the first evidence that a species adjusts its rate of sexual maturation in response to visual clues," Craig Walling of Exeter University's school of biosciences said.
"While our study focused on green swordtail fish, it seems unlikely that this attribute is limited to this one species," he added.
Green swordtail fish, a native of North and Central America, are named after the striking growth of the male's tail-fin which makes them look bigger and therefore more attractive to females which do not develop the sword-shaped tail fin.
OK, these guys are 'scientists.' My question, what the heck do they do on a daily basis to kill an 8-hour work day. They come in, measure the tail of the fish that day----then what?
Do they sit there all day and stare at the fish swimming around? Do they blog? Do they play gameboy?
Is their some reason they chose to find out that female green swordtails get turned on by males with large tails?
How much do these guys make measuring fish tails on a daily basis? I don't have a degree in bioscience but I think I could easily handle sitting around measuring fish tails and them coming up with conjectures on how that might affect members of the opposite sex.
It all seems pretty odd to me.
