Do snakes have 2 heads?
The addition of another head makes for a confusing time for some snakes. The two-headed monsters of myth may have a basis in reality. Two-headed snakes are rare but not unheard of, and one recently found in Spain is giving scientists an opportunity to study how the anomaly affects their ability to hunt and mate.
Why some animals have two heads?
One reason why an animal might end up with two heads is the embryo's incomplete splitting (or axial bifurcation). This is also why some humans end up being born as conjoined twins (though bicephaly is extremely rare in these cases).
Is there any 3 headed animals?
The condition is very rare but can occur in animals and humans. In ancient Greek mythology, there are lots of stories of many-headed creatures. But in reality only two or three-headed animals have ever been found. Two-headed animals are called bicephalic or dicephalic and three-headed animals are tricephalic.
Can turtles have 2 heads?
The rare condition of being born with two heads is called bicephaly. The newly-born turtle looks like a pair of conjoined twins, with two independently moving heads poking out of its green shell. When in water, each skull comes up at different times to breathe, and each head controls their own set of three legs.
Can Sharks have multiple heads?
When an animal has two heads it is said to exhibit dicephaly. The condition is relatively rare in the animal kingdom but has been seen in many different groups, from snakes to dolphins to people. (See the two-headed bull shark found by fishermen off the Florida Keys.)

Without special care, two-headed animals usually die early in their lives because they have difficulty escaping predators and foraging for food.
Are 2 headed sharks real?
Two-headed sharks may sound like a figment of the big screen, but they exist—and more are turning up worldwide, scientists say. ... The catshark embyro was not your average two-headed beast—it's the first such specimen known from an oviparous shark species, or a shark that lays eggs.
How do conjoined twins work?
Conjoined twins are two babies who are born physically connected to each other. Conjoined twins develop when an early embryo only partially separates to form two individuals. Although two fetuses will develop from this embryo, they will remain physically connected — most often at the chest, abdomen or pelvis.
Are there conjoined triplets?
It is unique, nevertheless, in respect to the way the 3 fetuses were united. In a previous review of the literature, only 3 cases of true conjoined triplets have been found. However, all 3 cases occurred in the 19th or early 20th century.
Are the oldest conjoined twins still alive?
According to the 2009 Guinness World Records, the Galyons were the oldest living set of conjoined twins in the world, and, as of 29 October 2014, possessed the world record for the longest-lived conjoined twins in history when they surpassed prior record holders Giacomo and Giovanni Battista Tocci.
How many heads can a snake have?

Why are some snakes born with two heads?
The snake's two-headed stature is called bicephaly, and it happens when an embryo begins to split into identical twins but doesn't separate all the way. The condition isn't unique to snakes—in humans, bicephaly results in conjoined twins.
How rare are two-headed animals?
Two-headed animals are considered in many cultures to be a portent of disaster, and they have frequently appeared in mythology. But although they are rare, happening in around one in 100,000 live births in the wild, two-headed snakes do turn up fairly frequently.
Are Terrapins good pets?
