This is a common question from all skink lovers. You cannot really tell a female skink from a male from just the way it looks. Most lizards you can but skinks are really hard to tell. The only way to know for sure is to go to the vet and they will x-ray the lizard. If your not planning to breed the skink it doesn't really matter.
Compare the skinks' heads. The head of the male Southeastern five-lined skink is wider and redder than that of the female skink.
Study the lizards' striping. The yellow lines of the male Southeastern five-lined skinks fade as they mature, and their bodies become brown all over. Females retain their striping throughout their lives.
Look at the skinks' tails. As male Southeastern five-lined skinks age, their tails turn gray. Females keep the blue tails they were born with.
Evaluate the lizards' behavior. The male Southeastern five-lined skink runs toward another skink with his mouth open. If the other skink shows aggression in return, it's a male. If it stands still or flees, it's a female.
Both male and female emus have blue on their necks. It is impossible to tell the male and female apart by appearance alone.
A female isn't coloured whereas a male has a red,yellow,blue or green chest.
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.
the boys have orange or red heads the females have five dull bluish stripes
Males are somewhat larger.
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.
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.
it does not have a pennies
the female is usually the one with ruffled wing from being mated with
