Is a tarantula either of the following?

I saw that someone answered that tarantulas are omnivores (meaning that they eat both animal and plant matter).  This is incorrect.  Most tarantulas are insectivores (they eat insects).  Some are considered carniverous however because they are large enough and do attack small mamals and birds.  Tarantulas really couldn't be omnivores because of their mouth structure.  It would be implausible for them to eat plant matter.  They are oviparous, meaning they lay eggs.  They lay the eggs in a cacoon-like egg sack which the female will carry with her in most species.  The eggs usually hatch in 4-6 weeks, depending on the species.  Hope this answered your question.

No. Probably not, but some people think they are now:\n"Spiders are the dominant terrestrial carnivore," said Ward Wheeler, curator in the division of invertebrate zoology at the American Museum of Natural History in New York and lead investigator for the U.S. $2.7 million Spider Tree of Life project. "They are all predators—they have a huge influence on the ecosystem."\nFrom:http://news.nationalgeographic.com/news/2003/10/1031_031031_tvspider.html

The Sydney Funnelweb Tarantula of Australia is very poisonous. Though not considered a "true" tarantula is still is a tarantula. What does that mean? Well, a box jellyfish isn't a "true" jellyfish because it is not syphozoan. It's cubozoan. But it is still a jellyfish to most people. There are some "true" tarantulas, usually from South America, that have enough venom to kill a large bird or make people need to go to the hospital but are not fatal bites. I forget its exact name but believe it or not I think its called a Bird-Eating Tarantula or something very close to that.

I think it is the Brazilian Wandering spider.\nThe Brazilian wandering spider is reputed to occasionally hide in clusters of bananas. As a result, any large spider appearing in a bunch of bananas should be treated with due care.\n\nThis spider is called the wandering spider because it wanders the jungle floor, rather than residing in a lair or maintaining a web. This attribute is another reason it is considered so dangerous. In densely populated areas, Phoneutria species usually search for cover and dark places to hide during daytime, and this may occur inside houses, clothes, cars, boots, boxes and log piles; thus generating accidents when near people.\n\nThe name Brazilian is given because this spider was discovered and documented in Amazonia. The antidote for their poison was developed by Carlos Chagas, in Brazil.

All life on Earth is related to some degree, so the answer has to be 'yes' for any two orgsnaisms you care to name. \n\nAre sharks related to dolphins? Yes.\nAre jellyfish related to bananas? Yes.\nAre bacteria related to ostriches? Yes.\n\nIn fact maggots and termites are fairly losely related, both being insects. \n\nMaggots are the larval form of various fly species, kind of like fly catterpillars. Termites belong to a 'primitive' group of insects that don't have a true larval form. Instead they hatch out looking like minitaure adults. So, although they are both insects, maggots and termites are about as distantly related as it's possible for two insects to be.\n\nThat makes termites and maggots about as closely related as a whale and a kangaroo.

depends on your meaning of spider, as camel spiders are not spiders, historically there is fossil evidence of an arachnid about 1/2 a meter in span, but wether it is a true spider or one of the other rlatives in the archanid clan is under debate (in addition some thing it may be a relative of an entirely different branch of animals which currently include the millipede). most of the largest current spiders sures as the bird eater and other varieties of the South American Goliath Tarantula are usually discribes as "dinner plate" in size.

Lmao!! This question cracks me up....couldn't stay away.\n\nThis is how I see it: Both would definitely be...well, let's just say, weird. Think about it though, if you were one inch tall imagine what other types of creatures will be roaming around down there with you. Snakes, spiders, ants (remember they can carry 100 times their weight) milipeeds, small rodents, beatles, ticks etc. etc. Imagine it...all just your size or larger.\nThen what? Suddenly you're dinner! \nGive me 20 feet anyday!\n\nThanks for the laugh! Wonderfully silly question.

Not sure but it ISN"T snakes and frogs. We have plenty here! Possibly a newt.

well, it definitely sounds like an arthropod, so the place to look would be a book or website with lots of pictures of different kinds of Arthropods - crustaceans, spiders, centipedes, insects, and more, they're all in the phylum Arthropoda.  Your arthropod sounds like it's in one of the lesser known groups.

I think it may help to clarify what the other 2 posters have said, as they have 'clouded' the issue a bit:\n\nThey lack external ears, have a diapsid skull (two openings on either side), and posess a "parietal eye" on the top of their head. Other lizards also have this "third-eye," which contains a retina and is functionally similar to a normal eye, though the function has not been clearly recognized and a scale grows over it in adult tuataras.\n\nAs it contains an actual retna, it can infact see.  But, to what extent, who knows.

The echidnas are sometimes treated as only two species and sometimes treated as 4, 5, or 8 depending on the authority.  Some consider Zaglossus bartoni and Z. bubuensis as subspecies of Z. bruijni.  Likewise, there are variants of Tachyglossus that have also granted species status by some authorities: T. lawesi, T. typicus, and T. setosus.\n\nThe three monotremes are the platypus: Ornithorhynchus anatinus, and the two species of echidna: Tachyglossus aculeata and Zaglossus bruijni. If 5 species are recognzied, the additional two are Zaglossus bartoni and Zaglossus bubuensis.

Spiders are arachnids.\n\nArachnids and insects are part of the group called ARTHROPODS.\n\nArthropods are invertebrate organisms with exoskeletons.\n\nArthropods include:  \n\nCrustaceans:  such as lobsters and crabs\nCentipedes\nMillipedes\nArachnids:  such as spiders\nInsects:  such as flies\n\nInsects have 6 legs and 3 body sections.\n\nI believe arachnids have 8 legs and 2 body sections.\n\nHowever, I am not completely sure about the body sections.

There are probably a lot of spiders that would fit\nyour description. More information is needed, such\nas where (geographically) the spider was seen, in\nwhat kind of habitat and at what time of year.  The\nvarious other answers mostly mention the garden\nor writing spider (Argiope), but it might qualify as\na large spider, depending on what you consider\nlarge.  Another eastern U.S. spider that sometimes\nhas a bright yellow mark and is smaller is another\nof the orb spiders, Verrucosa, which has a triangular abdomen and gets about a half inch long\nin body length.

Depends how fast someone steps on it.\nMost araneomorph spiders (orb weavers, huntsman, etc.) live from one to three years. Mygalomorph spiders (trapdoors, tarantulas) are generally much longer lived. Some large tarantulas species (Theraphosidae) take six to eight years to mature and live 20 years or more. A long life and continuing moulting and growth allows some of these species to grow very large - the legs of a large goliath spider (Theraphosa blondi) may almost span a dinner plate. \n\nFemale spiders generally live longer than males, this difference being especially notable in long-lived spiders like mygalomorph spiders - e.g., male funnelwebs mature in two to three years and then die about nine months later; whereas females mature in three to four years but may live for many years (six or more) after that\n\n\nHere is more info on the spider and a very interesting site about spiders.  Take a look at it you'll love it.\n\nSpiders are ancient animals with a history going back many millions of years. They have always been with us, an ancient source of fear and fascination. They are abundant and widespread and are natural controllers of insect populations. Wherever you live, you're always close to a spider. \n\n\nSpiders grow by periodically shedding their semi-rigid external 'skin' or cuticle of semi-rigid chitin and replacing it with a new larger skin they have grown underneath the old one (this is called ecdysis or moulting). This process includes replacement of every hair on the body and internal cuticular structures such as the fore and hind gut linings and female genitalia. Once they are mature most araneomorph spiders stop moulting. However, female mygalomorph spiders moult throughout life, although at longer intervals as they get older. This allows some species, particularly tarantulas (Theraphosidae), to grow very large. \n\nDuring the moulting process, which may take many hours, the spider is in great danger from predators, being soft-bodied and unable to move until its new cuticle has hardened. For this reason moulting is often done at night hanging safely in mid-air from a silk line; or sealed within a silk retreat or moulting chamber, e.g., in a curled leaf, a burrow, or under bark. \nSpider eggs develop and hatch within the egg sac, the larval spider undergoing at least one further moult before emerging from the sac. The number of growth moults varies between species, as well as with size and nutritional state. Poorly fed spiders will moult fewer times and become smaller adults. Most spiders undergo 5-10 moults to reach adulthood. Males often have fewer and faster moults. Extreme examples of this are given by the Magnificent spider (Ordgarius magnificus) and the Bird Dung spider (Calaenia kinbergi), both large, specialised moth catching relatives of the orb weavers. The males moult only within the egg sac, emerging as tiny, fully mature males along with their similarly sized and very immature sisters, which will take many weeks and moults to become large adult females. \n\nA spider's appearance can change considerably during growth from spiderling to adult, as indicated by these stages in Redback Spider development. Adult males and females also may look quite different, especially in respect of size and colour. Spiders with good eyesight like jumping spiders often have colourful or strikingly marked males which differ considerably from their drabber females.

More imformation would deffinently help. It is pretty much impossible to tell from the info you gave. What do you mean octagon spider? Does that refer to the web? Some helpful info would be the color, size, and shape of the spider, the shape, size, and location of the web, and where you found the spider (state, country, ect.). Any other information would also help. \n\nAnother thing to consider is that all spiders (other than a small, rare family) have venom. It is unlikely that they are very harmful, but again, I would need more information to say that for sure. Try a field guide (library is a good place to look) and see if you can find what kind it is, then research that one. If you want, post some more info here, and I will try to find it.

Insects are all hexapods.  Other arthropods have more legs, that's the essential.  If it has more than 6 legs, it's not an insect.  Spiders are not insects.
