Humans impact fish genitalia - Polidicks

nice

[QUOTE=Shogoll;46415051]nice[/QUOTE] omg WOW so insensitive can't we just have ONE of these threads with out this NEEDLESS comment?!?!

[QUOTE=Pelican;46415063]omg WOW so insensitive can't we just have ONE of these threads with out this NEEDLESS comment?!?![/QUOTE] [QUOTE=Shogoll;46415051][del]nice[/del] I am very impressed and surprised by the rapidity with which human kind has grasped the manipulation of fish genitals through ecological means. I am optimistic this genital morphing capability will be used for the benefit of our aquatic friends.[/QUOTE] [editline]a[/editline] [quote]Fish coexisting with predators in unfragmented areas have[b] bonier and more elongated [/b]gonopodium tips than fish living without threat of predation in fragmented areas.[/quote] Okay I need to go find the actual published report for this study now. [editline]a[/editline] I found the report; they photographed and measured 410 fish dongs and then photographed 235 of them under a microscope 5 times and made composite images of them. They assigned various features in the microscope images as landmarks and then performed a shit ton of computation and analysis on the differences in tip shape and tip features to correlate them with environmental effects. I get what they were trying to achieve and all, but holy shit its a bunch of PhDs and grad students going around measuring fish genitalia for weeks

So how much do these scientists get paid to play with fish cocks? I hope my taxes aren't paying for this dickery. That's enough penis puns I suppose.

Isn't this why people become scientists?

there are some people out there who would love to be impacting fish genitalia right now.

Fish dicks, the not so popular version of fish sticks.

[QUOTE=UserNotFound;46420546]I hope my taxes aren't paying for this dickery.[/QUOTE] If they are, I want to know what prick decided they should.

Have shark tits gone too far?

unlocking environmental mysteries, one fish penis at a time.

gives a whole new meaning to fish sticks [editline]5th November 2014[/editline] [quote]NC State Ph.D. student Justa Heinen-Kay and assistant professor of biological sciences R. Brian Langerhans show, in a paper published in the journal Evolutionary Applications, that the male genitalia of three different species of Bahamian mosquitofish (Gambusia) living in fragmented waters differ markedly from the genitalia of fish living in unfragmented waters.[/quote] so wait you're telling me this was like a class project kind of thing 'hey teach, what do I have to do in order to get a good grade or extra credit?' 'help me count fish cocks for a few weeks' [editline]5th November 2014[/editline] unless of course they both had in interest in fish dicks for some reason tbh that actually makes it kind of worse

kinda seems like rapid evolution would happen in any species which reproduces like every 30 days

For some reason when I read this title, I imagined this was a weird vague title talking about a group of people punching fish in the dick.
