The same with all skinks you cannot really tell there sex apart. If you have a blue tailed skink and you really want to know what sex is you can take it to the vet and they will x-ray it. You don't really need to know the sex unless your planning on breeding it. Its not worth the hassle for such a small little lizard. Hope this answers your question :))
boys have more of a red/orange head unlike girls, theirs is more brown.
size and color
A boy skink will have a bump underneath the tail a girl will have a closed up hole
A female isn't coloured whereas a male has a red,yellow,blue or green chest.
It depends on the species. e.g a common garden skink from Australia the females have an orange belly and the males have a light-grey/silver belly
Tell them how you feel. Do you love them? If not tell them.
A male Red-tailed Hawk may weigh from 690 to 1300 grams (1.5 to 2.9 pounds)
if on top of a parakeets nose is blue it is a boy if pink or white it is a girl.
you cant exactly tell when they arn't fully grown, but once they are adults the male will turn brownish black colored all over the body and the female will stay the same (blue tail, stripes, etc.)
you tell me
yes they do acctually there stripes on them are not as full color as other ones that live in virginiathe Florida ones tail is a very deep blue that you can barly tell its there and faint yellow stripes all over its body
you check on line
Well I have 3 blue belies at home one way to tell them apart is look at the size or color females are dark and small males are light and big
