On a male molly behind their anal fin is a pointed fin called the gonopondium. On the female it will be rounded.
Both male and female emus have blue on their necks. It is impossible to tell the male and female apart by appearance alone.
You can tell them apart by the gonopodium, a tube-like structure at the front of the anal fin. It is only present in the male of livebearers. Common livebearers include mollies, platys, swordtails, and guppies. the females have a fan like fin
The males have a modified anal fin, better know as a gonopodium, that can move various directions and is used to impregnate the female mollies. If you see a molly chasing after the others, take a good look at it, it's probably a male.
yes
Well one has male reproductive parts the other female parts
the blue one is male and the others female
Well, male and female aquatic turtles are easy to tell apart in a few years. If they are not at least 4inches long, you cannot tell what is a male or a female. A female is usually much more bigger than males when they are grown-up. Also, a female has a more broader head (neck) than a male. A male has a longer, thicker tail than a female, and it has much more longer, nastier nails than a female. Those are about it how you can tell them apart. I hope this helped you.
Males are somewhat larger.
if the mollies have great big knobs flappin around like a natarulist on a windy day, they are a male, if not : female!! but you can have sex with them!! :)
If this is a reference to emus, both male and female emus have blue on their necks. It is impossible to tell the male and female apart by appearance alone.
it does not have a pennies
well the male would have the male gonads and the female would have the female ones. You can tell them apart because the males would be outside the body.
