Which species have females larger then males?
817770
Most non-mammalian groups do. In mammals, the males are larger, but that is mostly realted to the fact that they fight for the attention of females and the chance to mate, so natural selection makes them bigger than the females.\nIn most other groups however, amphibians, reptiles, most insects, arachnids, many crustaceans and other invertebrates, the female is usually larger based on the simple fact that she must caryy eggs with her. Eggs are  much more bulky that live young, so the female must be larger in order to carry such a weight around. So, to answer your question, there are thousands, potentially millions of species that have larger feamles than males!\n\nlarge female, tiny male:\nhttp://bugguide.net/node/view/44206\n\nhope this answers your question!

I don't think they are strictly male....rather a type of penguin.  Check out the link:

Well all animals attract the opposite sex by the female of the species coming on heat.This function allows the female to attract the male over a wide area.Usually a dominant male breeds most of the females,this ensures that the resulting offspring are strong and healthy

The smallest species is probably the Dwarf Lantern shark {Etmopterus perryi), with total length of about 6 inches (16 centimetres) for mature males, and 7.5 inches (19 centimetres) for mature females. \nThe second smallest is the Spined Pygmy Shark (Squaliolus laticaudus), with 6 inches for males and slightly longer females (7.8 inches or 20 centimetres). \nAnother diminutive shark (although I'm not sure if it's the third smallest) is the Cookie-cutter shark (Isistius brasiliensis). It's bioluminiscent and grows up to about 1.5 feet (50 cm). \n\nAll belong to order Squaliformes, which includes the smallest sharks along with some good-sized species.\n\n----------------\nUpdate: I've learnt of another very small shark, Euprotomicrus bispinatus (22 cm total length for males, 27 cm for females). I guess that's the third smallest.

it is a hermaphrodite...this also occurs in many invertebrates including flatworms and some earthworms.  \n\nremember that a hermaphrodite does not mean that it mates with itself spontaneously, though.  it still needs a mate, but it can serve as either a male or female since it has both sets of reproductive organs.

My 1st reaction would be to say the lemur - but thats only coz their eyes are so big in comparison to the rest of their body.....the elephant is more in proportion but obviously a much bigger animal....I think this is a trick question so I will say the elephant has bigger eyes! Am I right??

There is no difference in spots. The male and female are hard to tell apart other than the female is slightly larger. Otherwise you have to use a microscope.

like it's already been stated, with spiders the female tends to be larger, also in some cases the female will eat the male when the fertilization is complete.\n\nBut as for a special chamber inside the female to store the male...never heard of that

hermaphrodites have both sets of sex organs.

That is a basic animal instinct of survival and perpetuation of the species.  The female of the species will always be more attracted to the winner, the more dominant, the strongest, the most attractive, etc. male because that male is more likely to produce strong, intelligent, attractive offspring.

The animals (cross between male tiger and female lion)are sterile but healthy, they are smaller than either of their parents.  The Liger, which is a cross between a male lion and female tiger, does not do so well, since they lack the growth inhibiting genes and continue to grow until their bodies fail from the stress.

There are male ladybugs too. \n\nIt's almost impossible for the average person to tell them apart. But here are some clue that might help. \n\nFirst, females are usually larger than males. Second, if you observe one ladybug riding atop another ladybug, they are in the process of mating. \n\nA male ladybug will grab the female's elytra (hard wings) and holds on tight. \n\nAn entomologist (bug scientist) can see the difference between males and females under a microscope.

In a classical sense, a female is not a predator. She entices and allures and many know this skill. Men are susceptible to feminine charm and hence sometimes fall prey.This is a criss-cross phenomena which will go on. Some female birds are also known to do that, although in many cases it is the male that has to allure the female, in a game of courtship.Some mammals in  heat draw males towards them. A female scorpion really devours the male after copulation.A female fish keeps the tiny male in its mouth so that he does not get lost.

They are individuals that have both male and female reproductive parts.  They are called hermaphrodites.

Orangutans (Pongo pygmaeus) currently inhabit only the islands of Sumatra and Borneo. Fossil evidence indicates that their past distribution included much of Southeast Asia.\n\nOrangutans are only found in forested areas, but can be found in various types of forests, from low-level swamps to mountainous areas 1.5 km in elevation. They can be found at various heights in the trees. They may move large distances to find trees bearing fruit.\n\nOrangutans are sexually dimorphic. Females range from 30 to 50 kg, whereas males are from 50 to 90 kg. Head and body length is about 1.5 meters and the arms have a spread of about 2.2 meters. They have a thin, shaggy coat that is reddish brown in color. Males have large cheek pads, which are made up of deposits of subcutaneous fat bound by connective tissue. These cheek pads continue growing for much of an adult male's life. Orangutans have a high, sloping forehead and a bulging snout. They have short, weak legs, but strong hands and arms.\n\nOrangutans are polygynous. Although mainly solitary, the home ranges of males overlap those of females. On the rare occasions that the females within their home ranges are sexually receptive, dominant males will mate with them. Younger, smaller males, which are not able to maintain home ranges of their own, often wander alone through the forests. These males may also mate with females, although such copulations are generally forced, and appear to occur as the opportunity arizes, not because the female is sexually receptive or fertile.\n\nFemale orangutans have an estrous cycle about 30 days in length with ovulation occurring around the 15th day. This species does not have genital swelling during estrous, and females have a light menstrual flow lasting 3 or 4 days. Copulation is usually done with the male and female facing each other, each hanging by the arms from a tree branch. Gestation can take anywhere from 233 to 263 days, and typically one offspring is born, although twinning sometimes occurs. Weaning occurs arounf 42 months, although the timing of this may be affected by habitat quality. The interbirth interval is about 4 years, but can be much longer if conditions are poor. In females, sexual maturity is reached at 7 years of age, by which time females have attained their adult size. Males, however, continue to grow until they are 10 years old, and do not have the physical and social maturity required for successful mating until about 14 years of age.\n\nNewborn infants weigh around 1.5 kg. Babies nurse every 3 to 4 hours, and begin to take soft food from their mothers' lips at age 4 months. A young orangutan clings to its mother's abdomen by entwining its fingers in and gripping her fur until it is a year old, then it begins to ride on her back, which it may continue to do until 2.5 years of age. An infant will scream loudly if separated from its mother. The young are not weaned until they are 3 1/2 years old.\n\nAll of the great apes live a long time. In captivity, orangutans may reach the age of 60 years, although the lifespan in the wild is probably shorter.\n\nOrangutans do not form large social groups. Individuals usually travel alone or in small groups consisting of 2 females, their dependent young, and occasionally an adult male. Generally males and females come together only to mate, and otherwise do not associate with one another. Males' home ranges are often 2 to 6 sq. km. in size, and overlap the ranges of several females but not usually those of other males, toward whom they are aggressive.\n\nOrangutans are active during the day (diurnal) and are almost exclusively arboreal. They can be found at various levels in the trees. They locomote by walking along and swinging from branches, descending to the ground only if they cannot move between trees via the branches. Each night they construct, using vegetation, a platform-style nest 40 to 60 feet high in a tree on which they sleep. They may descend briefly to the forest

As a general rule the vent or scaleless urogenital opening in a male largemouth bass tends to be more circular in appearance while the opening in a female largemouth tends to be more elliptical. Having said this, however, I should hasten to note that few biologists or fisheries managers rely on this method of determining the sex of a fish, because even to the well trained eye it results too often in mis-identification.\n\nInstead, at least during the spawning season, a much more reliable method of determining the sex of mature fish is to gently push on the fish's belly, back toward the tail. When you do this properly, you will often see a white milky substance (milt) flow from a male bass while a few eggs will be evident from a female fish.\n\nBeyond this very seasonal method, however, it is extremely difficult to distinguish between male and female largemouth bass. The only possible exception is when you catch a particularly large fish. As a general rule, largemouth bass bigger than eight or nine pounds are nearly always females.
