what percenage of non vertebra animals make up the animal kingdom?
142209
The exact figure varies depending on how it is claculated, but between 95 and 99.9% of all animal species are invertebrates.

The animal kingdom is enormous and we do not know for certain how many species there are in the world. Around 1.5 million species of animal have been named and described by scientists - and over a million of these are insects.

I would like to correct the other answer. MAMMALIA is the class of Marsupial Mammals. The Order of such mammals is MARSUPIALA. And I'm sure the phylum is CHORDATA.

Domain.\n\nThe classification system goes Domain (Eukaryote, Bacteria or Archaea), Kingdom (Examples: Animals, Fungi), Phylum (Example: Arthopoda), Class (Example: Insecta), Order (Example: Carnivora), Family (Example: Felidae [cats]), Genus (Example: Homo), species (Example: Homo sapiens), sub-species (Example: Bison bison bison)

um....there are a lot of them.\none example is the snake.  It is a mammal, and it's warm-blooded, and it doesn't have legs.  The fish family do not have legs and they aren't mammals and they're cold-blooded. If you're looking up a certain animal, just identify some of its characteristics and try to make sense out of it.

I would look here for your answer and/or a link that could get you your answer http://en.wikipedia.org/wiki/Vertebrate\n\nGood Luck!!!

nvertebrates are an extraordinarily diverse group of animals that include over 30 phyla. Invertebrates do not have a backbone, nor a bony skeleton. This large group of animals includes sponges, cnidarians, flatworms, roundworms, segmented worms, mollusks, echinoderms, and arthropods.\nSubtopics\nArthropods (290) Flatworms (6) Cnidarians (6) Mollusks (9) Echinoderms (7) Segmented Worms (5)

Birds, Definitely. birds, being warm blooded, are much closer to mammals than amphibians. Amphibians only show the faintest glimmer of an R-Complex, known in your brain as a cerebellum - the reptilian part of the brain. Birds, by contrast, have a highly developed R-complex and even show the beginnings of a cerebrum (the big lumpy part of your brain that handles all that rational though stuff). Can you imagine a frog or a salamander uttering, "Polly wants a cracker?" >:)

Terrestrial tetrapods have no spiral valve, more veination, large intestines, while fish may have spiral valves and no large intestines.

Question 1:\n5 Kingdoms- Monera, Protista, Fungi, Plantae, Animalia\nMonera:  are single-celled organisms with no organelles or cell nucleus. Often have cell wall in addition to cell membrane.  (includes all forms of bacteria)\nProtista: single-celled, have organelles and nucleus.  Include yeast.\nFungi: Multicellular, have organelles and nucleus, some go through photosynthesis and produce their own food, while others don't.  (includes mushrooms, bread mold, moss)\nPlantae:  Multicellular, organelles present, nucleated, undergo photosynthesis/so they have chloroplasts (includes all plants)\nAnimalia: multicellular, organelles, nucleated, cannot produce their own food, do not undergo photosynthesis.(animals)\n\nQuestion 2.  SOme say there are 6 kingdoms because Kingdom Monera is divided into Eubacteria and Archaebacteria.  Archaebacteria were the first organisms on the planet, and live under harsh conditions (volcanic hot spots underwater, etc).  Eubacteria are different in structure and are present in friendlier conditions (your bathroom floor, toilet, your intestines, etc)\nScientists do this to separate the two different types of bacteria...although most modern books have them all under Monerans

Yes, vertebrates DO have circulatory systems.\n\nPutting a question mark on the end of a sentence fragment copied from your homework does not make it a comprehensible question.

The answer to your question is twofold:\n\nThe bone structure of birds is indeed very different from that of mammals and other non-flying vertebrates. Their bones have a resistant outer layer, but the inner part is mostly hollow and in many cases invaded by the air sacs (part of the respiratory system). Therefore they're structurally different.\n\nOn the other hand, the structure of a bird's skeleton is different from mammals too. They have some fusions of bones that contribute to their stability and rigidity, and their hands have only 3 fingers. Their skull has no sutures, most have a keeled sternum and very different vertebrae.

Normally, it is considered to be Invertebrates the following taxa, though they do not include Hemichordata and Cephalochordata (Which are chordates but not vertebrates):\n\n- Protozoa: unicellular organisms\n- Porifera: sponges\n- Placozoa\n- Orthonectida: (Prev. Mesozoa)\n- Dicyemida: (Prev. Mesozoa)\n- Cnidaria: jellyfish\n- Ctenophora\n- Platyhelmintes: flatworms\n- Nemertea (= Rhynchocoela)\n- Gnathostomulida\n- Rotifera\n- Acanthocephala\n- Micrognathozoa\n- Gastrotrichia\n- Nematoda\n- Nematomorpha\n- Priapula\n- Kinorhyncha (= Echinodera)\n- Loricifera\n- Arthropoda: insects, spiders, crustacea, etc.\n- Annelida\n- Pogonophora\n- Vestimentifera\n- Echiura\n- Sipuncula\n- Mollusca\n- Phorona\n- Ectoprocta (=Bryozoa)\n- Brachiopoda\n- Entoprocta\n- Cycliophora\n- Echinodermata: sea stars, etc.\n\nYou can also include to de list Hemichordata and Cephalochordata.

>>>>>> Only vertebrates have teeth.\n\nThat isn't true. Lampreys have teeth and are not vertebrates. The radulae of many molluscs also have teeth.\n\nThe rest of your answer was spot on though.

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
