^^^ She's right. They are all sea life. \n\n\nBeyond that they have no commonality. They aren't even all from the same kingdom. Some are plants, some are animals, some are protists.

Porifera - pore bearers.  The body of a sponge is covered with tiny openings called pores. \n\nInvertebrate animals that live mostly in saltwater, but there are some species that live in freshwater. \n\nSponges are non-motile and depend on moving water currents. \nWater, food and Oxygen move in : Carbon Dioxide and Wastes move out \n\nSpicules- thin spiny structures that make up the skeleton of sponges. \n\nReproduction: \nSexual- egg and sperm are released into the water, forming new sponges. \nAsexual- budding, a piece breaks off and forms a new sponge which is an exact copy of the parent \n\nfor more information and pictures, specimens go to the link given below........\n\nEnjoy Lecturing........

Latin Name: Tubastrea, Tubastrea faulkneri, \nCommon Name: Sun Polyp Coral: Orange \nAlso known as Sun Polyp, Tubastrea \n\nFast Facts : Commonly called Sun Coral or "Sun Polyp", this is not a "polyp", as in a type of "Zooanthid" or "Polyp Rock", rather, it is a hard coral. It is non photosynthetic and should be fed for successful long-term maintenance. Offer frozen brine shrimp, mysis shrimp, finely chopped shrimp, seafoods, etc. Has been known to thrive for years in public aquariums, but requires dedicated care. Requires good water movement and dim or indirect lighting. Preferably, place in shaded areas of the aquarium.

courtesy of Encarta Encyclopedia Online!\nThe phylum of Cnidarians, or Coelenterates, is a phylum within Kingdom Animalia and consists of hydras, jellyfish, sea anemones, and corals. This phylum consists of over 9000 species. All cnidarians are radially symmetrical, meaning that they have a central axis and are symmetrical all around it. Their level of complexity is right above that of sponges, among the Metazoa, or many cells animals. In all cnidarians, the mouth leads directly into the gastrovascular cavity, a digestive cavity. This cavity is filled with fluid, which services internal cells, provides body support, and helps maintain structure. There is no anus, and so excess food and waste products must exit through the mouth. As a result, the digestive system of cnidarians is considered incomplete. Another characteristic of cnidarians is that they all have two layers of living tissue. The first layer of living tissue is known as the dermis, and the second layer is know as the gastordermis. The dermis is the outer layer, and the gastordermis is the inner layer which forms the body cavity. A gelatinous layer called mesoglea separates these two layers. Also, in all cnidarians, nearly all functions are performed by individual tissues, not organs, despite the fact that a very small number of them do contain organs.

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

Kelp is a great example of a multicellular algae (which is protist), like the "kelp forests" in Alaska.  Check it out.\n\nhttp://www.oceanlight.com/html/kelp.html

Yes, all of the sponges are part of Phylum Porifera, and everything within Phylum Porifera are sponges.\n\nThere are three classes of sponges within the Phylum,\nCalcarea, Demospongiae and Hexactinellida.  They are differentiated according to their structure and the spicules that make up the hard parts of the sponge.

Sorry, I hate correcting people, but cnidarians aren't sponges.\n\nSponges are of the phylum porifera.\nCnidarians are things like coral and jellyfish.\n\nSponges have lots of holes.\n\nThey have loads of ostia, which are the small holes all around it, where water goes in to the sponge.\nDepending on the species, they may have 1 to 100s of osculums, which are the larger holes at the top where the water comes out.

Irukanji? I don't know if I'm spelling it right but it's a type of small, deadly box jellyfish, cubozoa I believe.

Kingdom: Animalia\nPhylum: Cnidaria\nClass: Scyphozoa\n\nThis is true for all jellyfish. After that they split up into several Orders:\n\nStauromedusae\nCoronatae\nSemaeostomeae\nRhizostomae\n\nHope I helped.

Rather than type in a long list of names like Calimecita, I will just add one.\n\nQ:  Quadralaria pyramidalis  it is a type of Cnidarian seajelly.\n\nFor fun, I may come back and do A to Z with just species of jellyfish.\n\nEDIT\nOK, here is my seajelly only list. Sadly I am missing 3 letters. J, X, Y.  I know there has to be an X somewhere but my brain is failing me this afternoon.\n\nAurelia aurita\nBerenix thalassina\nCyanea capitulatta\nDipurena brownie\nEleutheroa charcoti\nFavonia bacheri\nGossea faurea\nHippocrene brittanica\nIrenopsis hexanemelis\nJ\nKanaka pelagica\nLeptobrachia leptopus\nMastigias orsini\nNemopsis bachei\nObelia corona\nPelagia colorata\nQuadralaria pyramidalis \nRhizostoma cruciata\nSarsia eximia\nTima cari\nUmbrosa lobata\nVersura maasi\nWandelia charcotti\nX\nY\nZygocanna costada

The only one I can think of is the shellfish called mussels.\n\nThese links should help you figure it out.

Alginates are produced by brown seaweeds (Phaeophyceae, mainly Laminaria).\nCarrageenan is a general name for polysaccharides extracted from certain kinds of algae. The seaweed Chondrus crispus, the source, is called carrageen in Irish.
