Toci1 - Anatomy by Tapejara Toci1 - Anatomy by Tapejara
In this anatomy drawing, only key organs have been highlighted this time. If you really want the other organs highlighted, please comment below.

Compass: some life forms on Toci1 needed help navigating through the dense forest that dominates the planet. They evolved a special growth filled with oil and a mechanism that helps detect where the planet's poles are located.

Skin: the skin of Toci1 is similar to snakes and they need to shed it regularly. Some shed portions of it over the course of their lives, while others have to shed the whole thing at once, leaving behind hollow shells of their image. This is used not only because of growth but to rid the body of skin that may have been burnt by ultra-violet rays, to mark territory, to rid the body of diseases etc.

Ribs: what sets Toci1's life forms apart from the others at first glance is their ribs. Their don't form circular cages but rather chain links. Each small bone are linked by extentible cartillage, allowing the ribs to expand (for breathing) but not contract (for protection).

Opifician: this unique organ gets its name from Opificium, which means manufacture in Latin. This organ's sole purpose is to create new organ cells to repair or replace damaged or discarded organs. This organ is especially vital for females.

Uterus: female life forms on Toci1 give birth through their backs. The uterus practically grows in the skin, giving the aliens a hunch when they are near birth. When the gestation period ends, the uterus in some species detaches from the ovaries and is discarded along with most of the old skin on the back. The process is much less painful than what mammals on Earth must go through. Afterwards, females cannot give have another offspring until the Opifician has created a new uterus.

Muscle: on Toci1, muscles coil around the alien's bones and are linked at the joints. The muscles still pull like ours.

Mucus glands: To help the animal swallow, a Mucus Gland is located in the back of their throats. The mucus it produces help food glide down their oesophagus without causing irritation.

Skeleton notes:

:bulletblue: all joints in the skeletal system have a sack of jelly that helps prevent friction.
:bulletblue: the skeleton of Toci1's life forms contains high amounts of aragonite and conchiolin, the same content that makes up the mantle of mollusks such as oysters on Earth. This makes the skeleton often toxic and unedible.
:bulletblue: the joints are either linked by clamps like the arm (such as with the femur) or with sliding spherical joints inserted in an enclosed space (such as the shoulder).

Honestly, this isn't the best anatomy drawing I've made imo.
