 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

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.

This website has detailed information about the characteristics of Chordates, which is another name
for Chordata.
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

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.
