what is the differance between an male and female crab?

Females are larger, overall, but males have bigger claws, to fight over the females.

I'm partial to crabs. They are misunderstood. Each one has their own personality and temperament. Some even do tricks. It's a shame we execute them so quickly upon discovery.

Here is what i found for you:\n\nThe Life Cycle of the Carribian Hermit Crab\n\n The reproductive organs of hermit crabs are located near and just below the crab’s heart and open to the outside at the base of the last pair of walking legs in the male. In the female, they’re located at the base of the middle pair of walking legs. Female hermit crabs usually lay their eggs shortly after copulating,  however they can also store sperm for many months. The eggs are fertilized as they are laid by passing through the chamber holding the sperm. The eggs are carried and hatched in a mass attached to the abdomen inside the shell.\n\n      The number of eggs is usually large, but depends on the crab’s size. The developing crabs go through four stages, two of which (the baupilus and protozoea) occur while still in the egg. Most crabs hatch at the third stage, the zoea. This is a larvae stage wherein the crab has several long spines, a long narrow abdomen, and large fringed antennae. The fourth stage of development is the magelops.\n\n      Hermit crabs are usually born in the ocean, near the shore. Because of this, hermit crabs cannot reproduce in captivity. After the crabs are born, they move inland away from the water, where they search for abandoned shells to inhabit. Hermit crabs then begin growing and developing through a process call molting. In this process, the crabs sheds their exoskeleton. During this, the crabs are extremely vulnerable and inactive, and usually find protection by burrowing in the ground. It takes around 10 days for their new exoskeleton to harden, and during this period the crab is able to regenerate any lost or broken claws or legs. A hermit crab can molt as often as every other month when they’re young, or every 18 months when they’re older. The life span of the hermit crab in the wild is up to 30 years, while those in captivity live 15 years at the most.\n\nTC

Here's a few:\n\nMost roaches are female.\n\nThe females can clone themselves.\n\nFemales only need to have sex *once* - they store sperm for later use.  \n\nFemales can produce in excess of one million eggs over the course of their lifetime.\n\nRoaches are necrovores - they only eat things that are already dead.

Crabs do not leave the body for surfaces like toilet seats and floors.  They move from body to body.  You would not be able to see a crab on the floor if you were standing up.  You can see them when you're close to them.  They're about the size of a pin head & can be clear or rust colored.\n\nAs a health care worker, I'm suprised that you wouldn't recognize this - and that you got so freaked out.

The simplest animals do not have seperate genders.  They are not male or female, but rather male and female combined.  We call them hermaphrodites, after a Greek mythological figure, the child of Hermes and Aphrodite who was both male and female.\n\nThat we are descended from hermaphrodites is demonstrated by our embryological development.  Before we're born, we all start off as neutral-sexed organisms, with both sets of the organs that will become testes or ovaries.  With a few exceptions, people with XX chromosomes lose the testes and the ovaries develop, making them female, while people with XY chromosomes lose the ovaries, develop the testes and become male.

there are the obvious physical differences, but I once heard our school psycololgist describe how males and females interact. Males have a pecking order of dominance. We are less likely to make eye contact. Women make eye contact and they maintain a closer physical presence. In short, women are more open with their feelings, and less defensive.

Color. Males have more of a red breast where females have more of a brownish color on their breast.

"Crabs" is a name for pubic lice. Call it what you want but they are little tiny bugs that live in your pubic hair and live off your blood by bitting your flesh. They are the same thing as head lice so if you get head lice you should also get checked for pubic lice.

The male and female reproductive "tracts" are homologous.  This means that they're similar in structure and evolutionary origin, but are different in function.

There is often confusion regarding the difference between a shrimp and a prawn. Physically they look very similar but there is one sure way to tell them apart. In shrimps or carideans the side plate of the second segment of the abdomen overlaps the segments in front and behind. Prawns, most of which belong to the family Penaeidae of the group Dendrobranchiata, have all the abdominal side plates overlapping tile-like from the front. A more fundamental difference but one impossible to appreciate in a single specimen is that female prawns do not brood eggs but shed them into the currents where they develop independently. It would therefore make sense to call all member s of the Penaeidae "prawns" and members of the Caridean "shrimps" and this is what most Australians do. King prawns and banana prawns are names understood in this continent for penaeids sold frozen at the markets. The tiny shrimps bought in cans or froz en are imported carideans. Confusion arises when we hear Americans refer to prawns as "shrimp".

i think i had heard somewhere that females have the red marking on a different side than the males do...i'm not positive about this though

The simplest definition of "female" versus "male" is this:\n\nIf it has a raised portion that can go inside, it's male. If it has a "hole" or recessed portion to go into, it's female.\n\nA connector is defined as something that joins two pieces of (something) together. \n\nThus a female connector is a joiner with a recessed portion that something can be inserted into.

None. Males and females are essentially the same during development until a hormonal event causes males to develop male genitalia. Because of this, we have some of the same physical characteristics and thus males have nipples.

Males are normally taller than females period.

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.
