The Chordates are animals that comprise the phylum Chordata. Taxonomically the phylum Chordata includes three subphyla: Tunicata; Cephalochordata, comprising the lancelets; and the Craniata, or Vertebrata. The common attributes of the Chordata include having, for at least some period of their life cycles, a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail. The phylum Hemichordata has been presented as a fourth chordate subphylum, but it now is usually treated as a separate phylum.
Tunicate larvae have both a notochord and a nerve cord which are lost in adulthood. Cephalochordates have a notochord and a nerve cord (but no brain or specialist sensory organs) and a very simple circulatory system. Craniates are the only subphylum whose members have skulls. In all craniates except for hagfish, the dorsal hollow nerve cord is surrounded with cartilaginous or bony vertebrae and the notochord is generally reduced; hence, hagfish are not universally regarded as vertebrates, though recent DNA comparisons suggest that they are in fact vertebrates. The chordates and three sister phyla, the Hemichordata, the Echinodermata and the Xenoturbellida, make up the deuterostomes, one of the two superphyla that encompass all fairly complex animals.
They don’t know,
They won’t see,
They won’t change,
They won’t be,
They won’t love,
They won’t go,
They won’t touch,
So they don’t know,
How much it takes for me to stay awake,
Dodging the poisonous darts you throw with your face,
I try to avoid the dark but it’s hard,
When you let go of me like rose pedals in the front yard,
One card, we play till we pass out,
Used to be my ace, now I’m feeling assed out,
So I back out the front porch,
While you reconsider what you really want more,
Me? Nah, I got a knack at leaving you breathless,
Bringing out the smiles that the angels eat for breakfast,
You deadest on watching me step,
Across a bed of coals just to see which arguments next,
Stress don’t leave when you’re next to me,
I’m my kinder side, you’ve got the best of me,
So let’s act like we don’t care,
There’s a moonlit path outside,
We should go there,
And make the clouds part,
I’ll grab you by the wings and you can guide me through the wild part,
Then that smile starts to speak,
Telling me why it’s been gone for weeks,
If it was all on me,
We’d get together right now,
Debate our different lifestyles,
And this is how it might sound,
They don’t know,
They won’t see,
They won’t change,
They won’t be,
They won’t love,
They won’t go,
They won’t touch,
So they don’t know,
What it’s like to wake up to a princess,
Eyes like a lighter, you spark my interest,
We invest too much to be selective,
Ingest solitude then redefine my objective,
Cause that necklace really makes me want to choke you,
Kill all the demons that grab your soul and hold you,
If I could mold you to just my shape,
I’d change absolutely nothing,
Mm that’s great,
Now that we got it all out on the table,
Come here baby girl I want to fuck with your halo,
Grab you by the hips and settle the score,
