 I’m the perfect match because I am very diverse. I can be whatever you want me to be such as…  Vertebrata: fish, amphibians, reptiles, birds, mammals  Urochordata: tunicates, sea squirts  Cephalochordata: lancelets

 I’m very active so I’m not boring at all! I also have a bilaterally symmetric body that are longitudinally differentiated into head, trunk and tail so don’t worry I’m very easy on the eyes. As you can see I can be cute, cool, beautiful, or strong. I have many personalities that can be perfectly compatible with yours

 You can decide where you want to find me depending on your preferences. I’m not hard to find. I’m basically everywhere  I can be found in marine, freshwater and terrestrial habitats from the Equator to the high northern and southern latitudes  You should go to an area where you feel comfortable so our relationship won’t be torn apart from environmental issues or I won’t be tempted to eat you

 I like to be active, eat, play, swim, walk around on land, search for food, and stay close to my family

 segmented body  three germ layers  well-developed coelom  single, dorsal nerve cord  tail projecting beyond the anus  pharyngeal pouches  ventral heart with dorsal and ventral blood vessels  closed blood system  complete digestive system  bony or cartilaginous endoskeleton

I have…  pharyngeal slits- a series of openings that connect the inside of the throat to the outside of the "neck". These are often, but not always, used as gills  A dorsal nerve cord - a bundle of nerve fibers which runs down the "back". It connects my brain to my lateral muscles and other organs.  A notochord - cartilaginous rod running underneath, and supporting, the nerve cord. This can either become my main axial support of the body, or it can disappear and be replaced by a vertebral column  A post-anal tail- this is an extension of my body past the anal opening.

 Someone’s who’s active and loves to play around  Someone who’s also willing to help me feed because since I’m active I’m always very hungry  Someone who can accept me for who I am

 Davis, U. C. "Characteristics of Chordates." UC Davis Teaching Resources Center. 19 Apr  This website has detailed information about the characteristics of Chordates, which is another name for Chordata.  Lundberg, John G. "Chordata." Tree of Life Web Project. 19 Apr  This website was very informational. It gave me information on the three subphylums of Chordata which are the Craniates, Urochordata, and the Cephalochordata. It went into small details about each subgroup and explained how they differed. From this, It helped me realize how diverse this phylum is. This website also had small details on the features of Chordata.  Myers, Phil. "ADW." Animal Diversity Web University Of Michigan Museum of Zoology. 19 Apr  This website was very helpful. It gave the basic features and characteristics of the Chordates. It showed how they were different from other species because of their notochord and other features of chordates that set them apart from other organisms. This was the first website I entered and it gave me a good  Waggoner, Ben. "Introduction to the Chordata." UCMP - University of California Museum of Paleontology. 19 Apr introduction to thisphylum.  This website helped me figure out the special features of the Chordata. I was able to figure out that there are four main features that Chordates all have in common.
