This is the typical body plan of the life forms of Planet Adam that are neither arthropods or coral. There are differences between species with the placement of the mouth or gills for example, but the above is the most common.

The specimen used for the display is a newly discovered predator. It is currently only known from several corpses that washed up partially devoured onto the shoreline. Surprisingly, the samples when put together provided enough information to create profiles.

This epipelagic predator is called a Dankagoni, which derives from the greek words Dankana and Sagoni which mean claw and jaw respectively. They modified their arms and claws to become elongated but thin jaws. The latter can rotate on an axis (the umbilical cord) and snap onto schools of small animals. After being impaled on the claws, food is then sucked into the mouth thanks to highly muscular cheeks. Water is forced out but hooked shape teeth pointing backwards prevent food from escaping. Bolus is then passed upwards into the stomach.

Dankagonies are solitary and individuals only get together to mate. When two males or two females meet, they will fight for territories with the most food available. Their streamline bodies allow them to achieve great speed when swimming. The rear most fins provide thrust while the side fins help with steering. Their eyes are on stocks to provide a better view of their surroundings. This is useful to look for prey and predators. The killer of the specimens is currently unknown as of July 7th 2014.

Here's the guide to the different organs of the above reconstructed specimen:

A. Nasal Cavity
B. Brain
C. Occular Muscles: the eye stocks also have cartillage in them to keep them erect.
D. Gills: the gills on Planet Adam work like our lungs. The vent expands and a muscle contracts to take in water. When the muscle relaxes, water is forced into a thinner tube and the vent tightens, which can create a small force of propulsion.
E. Swim Bladder
F. Armor: for animals to be flexible in the ocean, their armor is actually designed like a chainmail. A series of thick scales interlock to provide some degree of protection. Spikes are created when armor overlaps long vertebrae.
G. Bladder
H. Muscle Tissue
I. Vestigial legs: some species actually still use them to keep the second part of their bodies close to the primary part. Other species lost them altogether.
J. Intestines
K. Artery
L. Gonads: the above specimen is reconstructed as a male.
M. Mouth: this specimen's mouth is located in its pseudo skull, which is like a second skull but it's cover with joints for the jaws.
N. Jaws: this specimen modified its arms to to catch and impale fish. The 11 pairs of fingers act as teeth.
O. Oesophagus
P. Nerve
Q. Stomach
R. Liver
S. Heart
T. Head Kidney

There are some more organs that are not shown here. I actually almost forgot to draw the heart.

To wrap things up, note that Dankagonies have several features in common with most other animals on Planet Adam:
:bulletblue: body armor
:bulletblue: split body plans
:bulletblue: three possible genders (male, female and trimale)
:bulletblue: heavily muscular eyes that can look in two different directions
:bulletblue: bony but flexible fins

What an amazingly exotic body plan these creatures have, having practically a second head and body at the end of an umbilical cord. However did they evolve such a feature?

Not sure yet, more research will be needed.

If T is a "head" kidney, does that mean there are other kidneys?

The Head Kidney is a term given to the main excretory organ found in Earth's more primitive fish. The same name has been given to a similar organ found in most of Planet Adam's animals.

Oh. How are they different?

The head kidney is found closer to the head. Simple as that.

Trimale?

It's the best I could come up with. It has a suffix for three in it for the third gender.

So it is another form of male, possibly subdominant, but still required for reproduction? Interested to know more. I've been wrestling with something similar.
