Do Turtles Have Umbilical Arteries? Read This to Find Out Whether Turtles Have Umbilical Arteries.

Turtles are fascinating creatures that have been around for millions of years! They come in many shapes and sizes and can be found living all over the world. The most common species are pond turtles, snapping turtles, sea turtles, tortoises, box turtles, and terrapins.

Some people wonder whether turtles have umbilical arteries. The truth is that turtles do have umbilical arteries.

When a turtle hatches from its egg, it has a belly button, a scar where the umbilical cord connects the growing turtle to nourishment within the egg. The umbilical artery carries nutrients and oxygen from the mother to her baby during development.

In this article, we will discuss more of the things you should know about the umbilical arteries of turtles.

What is The Body Structure of a Turtle?

The turtle’s body is made up of a few unique parts. Its shell consists of two sections: the carapace and the plastron.

The carapace, or the upper shell, covers the turtle’s back, while the plastron, or lower shell, covers its belly. 

Inside the carapace lies a rib cage made of vertebrae and ribs. Connected to the rib cage is a pectoral girdle, which is an internal support structure that provides stability and protection. 

This part of the turtle’s body works differently than in other tetrapods — it sits inside the carapace rather than outside. Together, these features give the turtle its distinct shape and make it well-equipped for life in the water. 

Finally, turtles also have a tail, four limbs, and a head with a sharp beak used for eating. The turtle’s anatomy is distinct from other animals; however, its structure is incredibly effective — allowing them to survive and thrive in aquatic environments.

What is an Umbilical Artery?

The umbilical arteries are two small tubes that carry deoxygenated blood from the baby’s circulation to the placenta.

The ends of these vessels converge together at a point about 5 mm away from where the umbilical cord is attached to the baby. This connection between the two umbilical arteries is called Hyrtl’s anastomosis.

The umbilical arteries also provide nourishment to the baby while in utero. After birth, these vessels close off and become part of the umbilical cord. It is important for umbilical arteries to remain healthy during pregnancy for proper fetal development.

If any abnormalities are present, it can be indicative of a more serious problem. It is, therefore, important to seek medical advice if you think anything may be wrong with your baby’s umbilical arteries.

Why Do Turtles Have a Form an Umbilical Artery?

Turtles, like most other reptiles and mammals, have an umbilical artery. It is a small vessel that runs from the embryo’s yolk sac to the placenta during development.

This connection provides nourishment to the growing turtle by allowing oxygen and nutrients to pass through it. The umbilical artery also serves as a way for the mother to dispose of waste products from her baby.

The umbilical artery is essential for proper development, and if it is not functioning properly, the turtle may fail to develop correctly. While turtles have an umbilical artery, their anatomy does differ slightly in comparison to other species — such as mammals — due to their need to remain in the water.

The umbilical artery of a turtle is shorter and more muscular than those found in other animals, allowing them to use the pressure of the water around them to move nutrients and oxygen through their bodies. 


Turtles are incredibly unique creatures that have been around for millions of years. They have evolved to live in an aquatic environment and have form of an umbilical artery that helps them obtain necessary oxygen and nutrients during development.

This artery is different than those found in other animals — it is shorter and more muscular — allowing them to use the pressure of the water around them to move what they need through their bodies. Ultimately, the umbilical artery is essential for the healthy and successful development of turtles.

This content was written to provide an overview of why turtles have a form of an umbilical artery and how it differs from other species. It covers topics such as the body structure of a turtle, what an umbilical artery is, and why it is important for proper fetal development. It also explains how turtles’ anatomy differs slightly due to their need to remain in the water.

Ultimately, this information should provide a better understanding of why turtles have a form of an umbilical artery and how it works.

Frequently Asked Questions Related to Umbilical Arteries in Turtles

1. Are there two umbilical arteries for turtles?

Most turtles have two umbilical arteries in their bodies. These arteries, which both originate from the baby turtle’s heart, supply oxygenated blood from the mother to the baby.

The umbilical arteries are also crucial for exchanging metabolic waste between mother and adolescent turtles. 

2. Do humans have umbilical arteries?

Humans have umbilical arteries. They are the longest blood vessels in the human body, and they run from each side of the fetus to connect it to its mother’s placenta as part of a baby’s circulatory system.

3. What does the umbilical artery turn into?

In summary, after giving birth, the umbilical artery turns into an internal iliac artery plus one or more superior vesicle arteries, which help in supplying various organs with fresh blood in accordance with individual anatomy.
