It's difficult to tell the difference. Generally, female frogs are slightly larger and their skin color is a little lighter than males.

Figuring out what sex a frog is can be difficult, and will depend largely on what species it is. Generally, male frogs call while females do not. Male frogs also are usually smaller and more angular or streamlined in appearance, unlike females which are often larger and more robust. During the breeding season, males of many species will develop what are called nuptial pads on the inner part of their limbs or digits. See similar questions...

I wish I could give you a standard test you could try here. Unfortunately, there's really no easy way to tell. It really depends on what type of frog you have. Some frogs have only males that sing. If a frog has a vocal sac (the kind that blows up like a balloon) it's very likely to be the male of the species. But, there are species of frogs where both males and females participate in singing and sometimes the type of song they make is what is different. See similar questions...

First it is nearly impossible to tell the sex of fry. Some maturity is necessary to see the signs of gender indication, in species that have gender indication. For instance you know you have a boy and girl angelfish only when you see hatched fry. Other than that, angels can be very difficult to tell. In general the following can be used as markers in helping determine gender. However, as with the English language, for every rule, there are exceptions. See similar questions...

There is no difference in appearance, between males and females. About the only sure way to tell the sex of a squirrel is to turn it over and look. Index See similar questions...

The males are usually larger and may be more aggressive. Females, being of a smaller stature, may be more ideally suited as a house companion. Males tend to be more outgoing, and more forgiving of mistakes in training. Females tend to be less dominant and work well with children - however, many females may actually be more protective of their households than males. Nevertheless, generalities do not always apply, and it is best to ask the breeder for their advice. See similar questions...

Chickens: There are several "theories" but one I have found to be the most accurate....is using a nail, needle or ring, fastened to a 6-8 inch piece of sewing thread. Hold the string with the nail swinging freely above the chick. The string will swing in a circle if it is a female and back and forth if it is a male. You can try this over people's wrists. It is fun and makes for very interesting conversation. I do not know why it works but we have found it to be very accurate. See similar questions...

There's no practical way. Not unless you can do some bloodwork, or observe the bird during mating season. See similar questions...

The easiest way to tell is that the male hamster has a kind of extra bulge around the tail. But you can also turn them onto their back to check. You can see the difference between a male and female at See similar questions...

Sulcata Station's response: It is very difficult to determine the sex of a sulcata that is less than 10 to 15 pounds, or less than 12 inches in shell length. In fact, most sulcata owners *don't* know what sex their tortoise is until they witness it laying eggs, or everting its penis, or attempting to mount other tortoises. See similar questions...

For the most part, this is very simple. When they are young, or not completely mature, it is more difficult. The majority of the time, females will be short finned. They will also have an ovipositor between their ventral & anal fins. This looks like a small, white bump. They develop this when they are mature enough to breed. Males will normally have long, flowing fins. They are the typical picture that comes to mind when someone mentions a betta. See similar questions...

If you hope to show or breed, you want a dog of excellent quality. Study the most recent (1987) STANDARD, a description of the ideal Tibetan approved by both the American Kennel Club (AKC) and the Tibetan Terrier Club of America. Try to see several Tibetans and compare them to the Standard and to each other before you purchase one. Do be fair to the breed and the breeder and tell him what you expect of your dog.
