  • Porifer Animalia

    Kingdom: Animalia Phylum: Porifera Classification information for Poriferans: Poriferans, better known as sponges, consist of 5000 known species, all located primarily in marine and fresh waters (Myers, 2001a). They are multicellular, heterotrophic, invertebrates with an irregular shape and no distinct pattern of symmetry (Myers, 2001a). Overall, they are the simplest of animals; thus, lacking any true tissue and/or germ layers (Myers, 2001a). Furthermore, they are known to be highly sessile, and feed by collecting bacteria from the water that streams through their porous bodies (Myers, 2001a). Feeding is known to be distinct, as their flagellated cells called choanocytes, trap bacteria in mucus, which allows them to then engulf the food…

  • Importance Of Locomotion In Animalia

    Locomotion is the movement of a body from one place to another. There are various ways in which species of organisms in the 9 major phylum classes of the kingdom Animalia adapted unique muscle systems and how they use them. A phylum class includes organisms that are different but share important characteristics that resulted from evolutionary relationships among major groups of animals that allowed organisms to adapt in terms of the way they locomote. The Phylum Porifera is made up of sea…

    S, 2004). Their anatomy features Gram-positive, nonsporulating, polyploidic cocci, lacking flagella and motility and resistance to hydrogen peroxide and other agents that damage DNA because of a highly efficient DNA repair system. Although they are considered Gram-positive, they may be an intermediate between gram-positive and gram-negative bacteria and form a distinct bacterial lineage of extremophiles; the Firmicutes phylum has a diversity of microbes associated with the human gastrointestinal…

  • Chordates Research Paper

    The Chordata is the third largest phylum in the kingdom Animalia. Chordates are bilaterally symmetrical; meaning one half of their body is a reflection of the other half. The Chordata phylum has several general characteristics unique to only this organization of creatures. The first is pharyngeal slits, which are openings behind the head that connect to the throat. These are known as gills in some chordates. Humans have these in the womb but eventually form into the inner ear. The second feature…

  • The Evolution Of Chordates

    Chordates, which is the phylum or classification of fish and mammals of the sea, are the most developed marine organisms. Scientists believe that Chordates originated about 590 million years ago. The original organisms of the Chordata phylum are believed to have lacked skeletal structures, and therefore, left a very undetermined fossil record. The vertebrate fossil record begins approximately 400 million years ago. Early Chordates were tunicates, marine organisms that would frequently form…

    They are heterotrophs and depend on autotrophies. Krill are shrimp-like marine invertebrate animals. These are smaller zooplankton but it is important for larger marine mammals as food for baleen whales, whale sharks, seals, and a few seabird species. Krill phylum is Arthropod. Krill form key trophic link between primary producer and higher level in marine food web worldwide. The size range of krill is about two inches (five centimeters) in length.

  • Chordata Research Paper

    Chordata is a phylum of the animal kingdom that includes animals possessing notochord, pharyngeal gill slit and dorsal tubular nerve cord.
