They vary as widely as the body plans of different mollusks, but basically there are both macrophagous (herbivores and predators) and microphagous (suspension feeders) forms.\n \n**Gasteropods (snails and slugs) are mainly herbivorous; they use their radula to scratch plant tissues. However, there are also predatory snails (with modified radula, or proboscis, or even a venom-injecting radula). There are also microphagous planktonic forms (pteropods).\n**Cephalopods (squids, octopi and their relatives) are predatory carnivores, they have a modified radula and a horny "beak" with which they eat different invertebrates and vertebrates.\n**Bivalves (clams, mussels, oysters, etc) are primarily microphagous or suspension (filter) feeders. They don't have a radula and rely on their modified gills for filtration. There are also some primitive detritivores among the bivalvians.\n**The chitons (Polyplacophora) are grazing herbivores (with  radula).\n**The Scaphopoda (tusk shells) capture small food items (particulate matter) with their tentacles (captacula).\n**Other less known mollusks include the caudofoveatans (these capture foraminiferans and other very small organisms from sediments), solenogasters (these eat corals) and monoplacophorans (with a radula, but not much is known about their ecology).

Star fish have five *arms* (or, sometimes, multiples of five or six arms).  Their legs are called "tube feet" and are found in the grooves under the arms.  They have an even number of them!\n\nMost animals have an even number of legs because they are symmetrical along a single axis, so both sides end up looking the same.  The only way to have an odd number would be to not be bilaterally symmetrical (and the only animals who aren't don't have legs!) or to have a leg in the middle, which wouldn't be much use.\n\nThe only "exception" to this would be an insect-like animal called the springtail.  It's not really a leg, but they do have their abdomen bent over and underneath them.  They use it to spring very high into the air, so you could call it a leg of a sort.  Sprintails are neat.  They are very common, but most people never notice them because they are mostly quite small.

Yes... the link below calls them optical tentacles, but that's a fancy way of saying "eyes".

Animals have 2 or more. Humans have 1. \n\nLook at a cat or dog for an example of a double eyelid. They may have their outer lid open but there is a membrane underneath that slides back and forth to block out light or let it pass through. That is something that people just don't have.

Well in theory, if a large cat were to have uniform spacing of dark and light spots on it, then the number of spots would be about 1/7 of the number of hairs on it's body.  There are appx. 100,000 hairs on the human head, so I might imagine that there are as many as 1 million on the body of a leoard.  That would be about 150,000 spots, except at that ratio it would only appear as a shade of color, so it would have to be significantly less than that when the human eye could see individual spots, I'd guess at least 3 hairs between each spot.\n\nSo based on my assumption of 1 million total and about 3 hairs in 6 directions (commonly accepted spread in geometric world, look at a Chinese Checkers Board).  But the spot itself would probably have to have a minimum of 3 hairs in it to be seen.  So 3/21 or 1/7 like I sid rearlier so 150,000(142,000) number was about right.\n\nI don't know the exact numbers, but I'm sure 150,000 spots would be well within the knowledge of God if a person has 100,000 hairs and he knows them all.\n\nMatthew 10\n29Are not two sparrows sold for a penny? Yet not one of them will fall to the ground apart from the will of your Father. 30And even the very hairs of your head are all numbered. 31So don't be afraid; you are worth more than many sparrows.\n\nAlso recorded in Luke 12

Hi,\n\nAccording to this site:\nhttp://www.tonmo.com/articles/articles.php\n\nOctopus has three hearts.\n\nQuote:\n"Does an octopus really have three hearts?\n...and how do they breathe? I've been asked these questions on a few occasions. \n\nThe fact is that octopuses do possess three hearts. Each has an important role in fueling the impressive respiration and circulatory system of the octopus."

In a few sea urchins, the spines are tipped with venom sacs.If a predator attacks the urchin, it may rupture the venom sac at the same time the skin of the predator is punctured. Venom is then introduced directly into the wound along with a portion of the spine that continues to lacerate the tissue.\n\nThere is one more elaboration of spines seen in sea urchins, and that is the development of structures called "pedicellariae." Pedicellariae are constructed of several small spines which have become modified to articulate with one another and function as snapping jaws. Each pedicelliaria is typically found on an elongate and extensible stalk, and they reach out to pinch any small animals or body parts, such as the adhesive tube feet of a predatory sea star, that threaten the sea urchin.\n\nSome urchins, particularly the blue tuxedo urchins, Mespilia globulus, use some of their tube feet to attach and hold shells, small rocks or debris to their surface. These attachments are thought to be "tactile" camouflage; basically a way to hide the urchin from predators that lack eyes, such as sea stars. If a sea star encounters the rocks on the surface of a small sea urchin, it may not perceive of the urchin as prey sufficiently rapidly enough, allowing the urchin to escape its grasp.

All mammals are set up on a bilateral plan. Two arms, two legs, two eyes, two ears, two nostrils, two halves of the mouth and ideally are identical on either side. It has to do with the way the cells divide. So, humans would have to have an even number of nipples to maintain this symmetry.

No, my best friend has one brown eye and one green eye and she's perfectly normal. It's called "Heterochromia iridium" and is rare in people but common in some dogs.\n\nBTW, the aforementioned friend is not a dog.

Mostly they are the shells of mollusks same phylum as clams scallops and snails.\nSome, startfish, sea urchins,  and sand dollars, are echinoderms.

Rotifers   are the only I can think of  now if it were Phylum Mollusca it could be Snails, Clams, and squids\n                                 good luck

(www.google.com)\n(www.wikipedia.com)\n\nHere the site in sources, I looked starfishes up in google and this is one of the search sites it came up with.\n\nPut this info below in your own words because this info is from copywright google:\n\nThe Class Asteroidea ("star form") includes animals commonly called starfish or sea stars.  Most forms have a flattened and flexible body with a varying number (often five) arms, or rays, arranged around a central disc. The oral surface (the side with the mouth) faces the substrate.  The "top side" (aboral surface) contains the anus and the entrance to the water-vascular systems called a madreporite.  Water enters the madreporite and is delivered through a system of canals to the tube feet, which are equipped with suckers that can adhere to the substrate or their prey (often bivalves).  Although beautiful, some starfish are regarded as serious pests to the oyster, clam and mussel industry, and the crown-of-thorns starfish (Acanthaster planci) can severely damage Pacific coral reefs by its grazing activities (i.e. feeding on the coral polyps). \n\n\nGood luck
