An invertebrate is any animal without a backbone. Invertebrates make up 95% of all species of\nanimals on the earth, and the variety of invertebrates is enormous. Scientists group or “clas\nsify” all of these different types of animals into broad categories called phyla, on the basis of\ntheir patterns of symmetry and on the basis of their overall body plan. There are 5 particularly important\ninvertebrate phyla (and another 23 or so less important phyla). The major invertebrate groups are classified as:\n· Phylum Cnidaria: sea anemones, corals, and jellyfish\n· Phylum Annelida: segmented worms\n· Phylum Mollusca: clams, snails, and squids\n· Phylum Arthropoda: lobsters, beetles, crabs, and flies and scorpions\n· Phylum Echinodermata: sea urchins, sea cucumbers, and starfish\n\nsee more info at:http://www.msc.ucla.edu/oceanglobe/pdf/Invertebrates/Inverts_Entire.pdf\n\nI hope this helps...\n\nDon

Hemichordata is a phylum of worm-shaped marine deuterostome animals, generally considered the sister group of our own, the chordates. They date back to the Lower or Middle Cambrian and include an important class of fossils called graptolites, most of which became extinct in the Carboniferous. They seem to have a primitive form of notochord, but this is most likely the result of convergent evolution. A hollow neural tube exists among some species (at least in early life), probably a primitive trait they share with the common ancestor of chordata and the rest of the deuterostomes.\n\nHemichordata are divided into two classes: the Enteropneusta, commonly called acorn worms, and the Pterobranchia, which may include the graptolites. A third class, Planctosphaeroidea, is proposed based on a single species known only from larvae. The phylum contains about 100 living species. The exact taxonomic position of hemichordata and whether the group is monophyletic is currently under debate.

Sponges (from Latin porus "pore" and ferre "to bear") are animals of the phylum Porifera. They are primitive, sessile, mostly marine, waterdwelling filter feeders that pump water through their matrix to filter out particulates of food matter. Sponges are among the simplest of animals. With no true tissues (parazoa), they lack muscles, nerves, and internal organs. Their similarity to colonial choanoflagellates shows the probable evolutionary jump from unicellular to multicellular organisms. There are over 5,000 modern species of sponges known, and they can be found attached to surfaces anywhere from the intertidal zone to as deep as 8,500 m (29,000 feet) or further. Though the fossil record of sponges dates back to the Precambrian era, new species are still commonly discovered.\n\nThe structure of a sponge is simple: it is shaped like a tube, with one end stuck to a rock or other object and an open end, the osculum, open to the environment. The spongocoel, or interior of the sponge, is composed of walls perforated with microscopic pores that allow water to flow through the spongocoel.

There are none. The sponge's main function is to filter feed through the ocean. Their cell structures are specifically designed to do just that. So, because they are on the lower rungs of evolutionary history, they have not evolved sufficiently to have a respiratory and circulatory system.

Richard Dawkins has two wonderful chapters on cnidarians (jellyfish) and poriferans (sponges) in 'The Ancestor's Tale.'\n\nCnidarians have two body plans, the medusa (jellyfish) and the polyp (sea anemones and hydras).  Polyps often reproduce by budding and can make huge colonies of organisms.  The portuguese-man-of-war is actually a complex colony of medusa and polyp forms.  (BTW, he has a great discussion about how the stinger cell in jellyfish may be the most complex structure in any cell anywhere in the animal and plant kingdoms. Way cool!)\n\nPoriferans (sponges) are even simpler organisms.  Although they are ostensibly multicellular organisms, with several types of cells, these cells don't organize themselves into specialized tissues and organs. Sponges are able to reproduce both asexually and sexually.\n\nSo the evolutionary significance is that an individual is basically a colony.  As such they are right at the boundary between single-celled and multi-celled creatures.  They demonstrate how multi-celled organisms could arise as a colony of cooperating single-cells.

Coral and hydra are both in the phylum Cnidaria, but hydra are in the class hydrozoa and most coral in anthozoa.  Hydrozoa have two body stages: medusa and polyp, whereas anthozoa only have one: polyp.  Coral often live in large colonies, whereas hydra do not.  Coral are mostly dependent on food from their symbiotic relationship with algae- not so with hydra (but they can form sybiotic relationships with some algae), therefore depend on growing in sunlight.  Coral can also grow much larger in size.

If you removed all the sponges, you would remove some of the mass in the ocean displacing water. So in fact, the ocean would not be deeper, but shallower. \n\nI will leave it to the reader to estimate the reduced depth after sponge removal.

Butterflies are classified in the phylum Arthropoda, class Insecta, order Lepidoptera. The true butterflies form the superfamily Papilionoidea, and the skippers form the superfamily Hesperoidae.

Protists:  CLICK LINK BELOW FOR NAMES AND PICTURES ! YOU SHOULD BE ABLE TO PRINT THAT PAGE.\n\nSlime molds and algae are protists.\nSometimes they are called the odds and ends kingdom because its members are so different from one another.  Protists include all microscopic organisms that are not bacteria, not animals, not plants and not fungi.\nMost protists are unicellular. You may be wondering why those protists are not classified in the Archaebacteria or Eubacteria kingdoms.\nIt is because, unlike bacteria, protists are complex cells. \n \nThese delicate looking diatoms are classified in the protist kingdom. (Click link below for names and pictures.)

1. Porifera (sponges), Cnidaria (jellyfish, coral polyps etc.), Ctenophora (comb-jellies), Placozoa (Trichoplax)\nIf we are speaking only about animals with distinct tissues, we must exclude Porifera.\n\n2. Mesoderm gives rise to muscle, connective tissue and circulatory system. So there are no specialized muscle cells (only "skin-muscle" cells) and no circulatory system in those animals. There are other parts that will be missing from those animals but not due to the lack of mesoderm - e.g., organ systems as such (even flatworms have defined digestive and excretory systems, for example).

Within a sponge, there is an intriguing body structure. While the sponge functions as a unified organism, each cell is a division of its own mini-organism. Essentially, a sponge is a combination of billions of cells that function together. Within the body of the sponge, several processes occur which are vital to its welfare. Most importantly, sponges conduct the processes of respiration, digestion, protection, development, and reproduction. \n\nAll of these processes are generated by the consistent filtration of the water encompassing it. Through an intricate system of incurrent and afferent ducts, it processes food, oxygen, and other useful materials. The exterior layer of skin is covered in pinacocytes, which open the afferent ducts. In addition, the afferent ducts allow water to be transferred through the porocytes. The functions of the afferent ducts are regulated by the myocytes, muscular cells that permit them to open and close. After this the water travels through the incurrent ducts. \n\nWithin the system of incurrent ducts, water is processed for useful materials. The interior layer of tissue forces the water through the ostioles into chambers lined with choanae and flagellates. Eventually, water is directed towards the atrial cavity. After the water is processed through the atrial cavity and removed of a sufficient amount of oxygen, it is released through the osculum. The osculum is a relatively maximized opening in the body of the sponge. At this point in filtration, waste water will be ejected.

Depends what you mean. From a utility point of view, yes it certainly is. Sponges have been made from sponge, from cork and from loofahs. Today most sponges are made form plastic. So by that standard it's a sponge.\n\n\nIn biological terms no, it's not. A sponge is an animal that lives in the sea. A loofah is the dried remnants of a type of squash. It's a vegetable.
