Etymologies

Sorry, no etymologies found.

Examples

  • Mammals are then grouped with the classes of other backboned animals, such as reptiles, into a "subphylum," Vertebrata, which is part of the "phylum" Chordata, containing all animals which have a nerve chord at some time in their life cycle.

    Lazarus, Elvis, zombies and Jimmy Hoffa

  • Most members of the chordate phylum, those in the subphylum Vertebrata, replace the notochord with vertebrae (the backbone) later in development to support the pelvic and pectoral girdles (to which the front and hind limbs are attached) and to protect the spinal cord.

    Haeckel had a point - The Panda's Thumb

  • Representatives of only a part of just one subphylum, terrestrial vertebrates, were rescued.

    Pity the poor inverts - The Panda's Thumb

  • It's but one of many such birds from the subphylum "Talkus Non-Interruptus."

    Dave Hackel: "The Hannitus"

  • This text, for example, lists Tardigrada (water bears) as a class within the subphylum of Arachnida in the phylum Arthropoda - as opposed to the current classification of Tardigrades in their own phylum.

    New art

  • This subphylum contains scorpions, spiders and "sea spiders".

    Arthropoda

  • All members of this subphylum have chelicerae and pedipalps as their first and second prosomal appendages.

    Arthropoda

  • Based on just this one particular example, then, it appears that design extends into the phylum Chordata, past the divide between invertebrates and vertebrates, which is the level of subphylum.

    The Edge of Evolution

  • Slightly but only slightly more serious - H. sapiens is willing and able to mate with the entire subphylum, let alone the genus.

    Randy Neanderthals? - The Panda's Thumb

  • All then arrive at the pharyngula stage, which is remarkably uniform throughout the subphylum, consisting of similar organ rudiments similarly arranged though in some respects deformed in respect to habitat and food supply.
