what information on starfish do people have. like where they live, what they eat, things that i can use?

Where they live:  "There are about 1,800 living species of sea star, and they occur in all of the Earth's oceans. The greatest variety of sea stars are found in the northern Pacific Ocean."\n\nWhat they eat:  "Some species take advantage of the great endurance of their water vascular systems to force open the shells of bivalve molluscs such as clams and mussels, and inject their stomachs into the shells. Once the stomach is inserted inside the shell it digests the mollusk in place."\n  \nGood luck! :)

Depends entirely on the species of star fish.\n\nThere are about 1800 different species of sea star (Echinoderms of the Class Asteroidea) and they occur in all of the world's oceans.  Some are adapted to live in warm, coastal seas and coral reefs, others prefer deep, dark cold environs.\n\nThere are even some that are found around the super-heated waters of the deep sea hydrothermal vents also known as 'black smokers'.

Hey.. go to this article in Wikipedia, it should help you out in answering your jellyfish questions.. http://en.wikipedia.org/wiki/Jellyfish

Marine invertebrates usually consist of the phylum porifera, cnideria, coelenterata, arthropoda and mollusca.\nInvertebrates like zooplankton are the major source of food for marine filter feeders like whales. Sponges are known for their beauty and some sponges are used as bath sponges.Jelly fish are useful scavengers.Arthropoda are widely used by humans as seafood -- namely crabs, prawns, lobsters etc. Mollusca are also used as seafood, and for the immensely profitable pearl industry.

Starfish commonly reproduce by free-spawning: releasing their gametes into the water where they hopefully are fertilized by gametes from the opposite sex. To increase their chances of fertilization, starfish probably gather in groups when they are ready to spawn, use environmental signals to coordinate timing (day length to indicate the correct time of the year, dawn or dusk to indicate the correct time of day), and may use chemical signals to indicate their readiness to each other.\n\nFertilized eggs grow into bipinnaria and later into brachiolaria larvae, which either grow using a yolk or by catching and eating other plankton. In either case, they live as plankton, suspended in the water and swimming by using beating cilia. The larvae are bilaterally symmetric — unlike adults, they have a distinct left and right side. Eventually, they undergo a complete metamorphosis, settle to the bottom, and grow into adults.

Most starfish reproduce in a method similar to the sponge. The starfish gather in a group (using environmental signals to coordinate the timing), metamorphose into juvenile sea stars and can begin living on the ocean floor.\n\nSea stars are developmentally (embryologically) known as deuterostomes. Since echinoderms and chordates share this same embryological pattern, they are thought to be closely related. Nevertheless, as these creatures are invertebrates and not actually fish, most marine biologists are pushing to completely replace the term starfish with sea star.

I used to keep fish. Goldfish to start with, along with Black Mollys, then got into tropical fish and then a salt water tank. It's a lot of work though, and can take up a lot of space, especially with a bigger tank and the equipment needed for a bigger tank. You want them to have enough space so they're not overcrowded.\n\nGoldfish are pretty easy and there are many ready-to-feed foods (flakes for example) for goldfish in pet stores. Get a book about goldfish (or other fish) or do research on line. Online might be best as the information would likely be more current.\n\nOther examples of "easier" fish and what they eat are:\n\n"GUPPY (Poecillia reticula):\nMiddle America: Prolific breeders. Males are very colorful. Active and peaceful. Livebearer.\nFoods: Flake Food. \n\nBLACK MOLLY (Poecillia sphenops):\nMexico to Venezuela: Suitable for beginners. Active, peaceful, eat algae. Prefers hard water. For propagation, breeding traps are recommended. Livebearer.\nFoods: Flake Food. \n\nSWORDTAIL (Xiphophorus helleri):\nMexico, Guatemala: Easy to maintain, but prospers only with varied diet. Livebearer.\nFoods: Flake Food, Color Food, BloodWorms. \n\nPLATY (Xiphophorus macalatus):\nMexico, Guatemala: Essential for beginners. Brings life and color to the aquarium. Livebearer.\nFoods: Flake Food, Color Food, BloodWorms. \n\nPEPPERED CATFISH (Corydoras paleatus):\nMiddle Amazon: Peaceful, charming bottom dweller. Feels more comfortable in an aquarium with small gravel or fine sand. Will clean up leftover food from the bottom. Scavenger.\nFoods: Tablets, Granules. \n\nSUCKERMOUTH (Plecostomus punctatus):\nAmazon: Peaceful bottom dweller. Prefers to eat at night, therefore, add one Tablet per large fish before turning off the lights. Scavenger.\nFoods: Tablets, Granules."\n\n-- http://home.ivillage.com/pets/birdssmallpets/0,,30n7,00.html

Your friend is correct. The starfish in question is a large spiny species called the Crown of Thorns (Acanthaster planci).  It can reach 3 feet in diameter.  Most snails don't eat starfish, but one does, namely the Pacific Triton (Charonia tritonis).  It would be bad enough if these large snails actually were overcollected for food.  But that is not the case.  They have been overcollected primarily for their large and beautiful shells, which are sold in gift shops and tourist shops all over the world, as decorative items.  The species is now protected in many areas, including the Great Barrier Reef, and is now making a successful comeback. \n\nHere’s a pic of the Crown of Thorns:\n\nhttp://ryanphotographic.com/images/JPEGS/Acanthaster%20planci%20Crown-of-thorns.jpg\n\nHere’s the living snail attacking a Crown of Thorns:\n\nhttp://members.cox.net/arniesdca/shells/charoniaOnCrownofTh.jpg\n\nAnd here’s a picture of the triton shell:\n\nhttp://www.conchking.com/Pacific%20Trtons.jpg\n\n.

We live in a land surrounded by sea.  It is a dry land.  Funnily enough we have more dangerous land creatures than sea creatures.  Snakes, spiders and other Australians account for more deaths than sea creatures.  We respect the ocean and use it as our playground.  We even try to stop illegal fishing.  We protect sharks.  We research the stingers (jellyfish), we research snake and spider venom, we try to control introduced pests like pigs and we try to be proactive in the management of resources.  We even have sea snakes that have the potential to be the most venomous animals alive.  The scorpions also leave a lot to be desired as the worlds less lethal beasties!\nI presume you are American, therefore I challenge you!\nIf you can assure me that I will not be mugged in New York, I will assure you you that you will not be stung by a stinger, eaten by a Great White, stuck by a ray or eaten by an eight foot tall carnivorous kangaroo.  Sounds like good odds to me.

"Sea stars" are "top predators" Try searching on those key phrases. Also try "keystone predator"

Daphnia magna.\n\nTry an aquarium shop. They're a popular live food for aquarium fish.

Invertebrates, the starfish can turn its stomach inside out. It will the surround its prey and digest the food.  When the food is digested the stomach will return to its normal position.\n\nNasty eh?

Starfish come in various sizes. As small as 1/2 " and I have seen them as large as 10". so the weight depends on the size.  But the average 3" starfish weighs about 3 oz.

One large marine snail, Charonia tritonis, feeds on the crown of thorns starfish. When these beautiful snails were overcollected for their shells, the crown of thorns multiplied rapidly and began destroying parts of the Great Barrier Reef. The snails are now protected and the situation is coming back under control.\n\nCharonia tritonis shell: http://www.hausdernatur.de/hnctrit.jpg\n\nCrown of thorns: http://ryanphotographic.com/images/JPEGS/Acanthaster%20planci%20Crown-of-thorns.jpg\n\nCharonia feeding on crown of thorns: http://members.cox.net/arniesdca/shells/charoniaOnCrownofTh.jpg\n.
