How many legs do snakes have?
Complete answer: 1)The convergent evolution has resulted in the formation of snakes without any limbs, so basically snakes do not have any legs and thus snakes are known as limbless reptiles.
Do snakes have legs or feet?
And those are the remnants of the fact that snakes came from lizards, and lizards have feet. So although there’s no leg on the snake, there are toes. SPEAKER 1: Snakes have toes. Now you know.
Do snakes have no legs?
A. Snakes are reptiles with no legs. They move by using their muscles to push their scales against the ground or other objects. This is actually a semi-hibernation state when the snake sleeps most of the time and doesn’t eat very much.
What kind of snakes have legs?
Snakes do not have legs, though some species (pythons and boas) have a vestigial pelvic girdle and two vestigial legs which are externally visible as spurs on either side of the vent.

What looks like a snake but has legs?
Skinks almost seem to be a cross between a lizard and a snake: they have a slick, polished feel and appearance like a snake, without a discernible neck, but they have the legs and body shape of a lizard.
Does snake have legs before?
Snakes used to have legs. Now they have evolved, but the gene to grow limbs still exists. Imagine a snake that has legs but can still slither. That’s how snakes used to be, and there’s evidence that legs have reemerged in some snakes.
Which animal have no legs?
Reptiles have on a number of occasions evolved into limbless forms – snakes, amphisbaenia, and legless lizards (limb loss in lizards has evolved independently several times, examples include the families Pygopodidae and Dibamidae and species of Isopachys, Anguis, and Ophisaurus).

Does a snake have 2 legs?
Explanation: Snakes do not have legs, though some species (pythons and boas) have a vestigial pelvic girdle and two vestigial legs which are externally visible as spurs on either side of the vent.
How did snakes evolve to lose their legs?
About 150 million years ago, snakes roamed about on well-developed legs. Now researchers say a trio of mutations in a genetic switch are why those legs eventually disappeared. Taken together, the mutations in the enhancer of a gene known as “Sonic hedgehog” disrupt a genetic circuit that drives limb growth in snakes.
Why are snakes lost their legs?
The research suggests that snakes evolved from lizards that either excavated on land or swam in the ocean. However, the legs grew obsolete in either case as the animal evolved over time. It seems that they lost their limbs because the presence of limbs impeded aquatic locomotion .
How did snakes lose there legs?
Comparisons between CT scans of the fossil and modern reptiles indicate that snakes lost their legs when their ancestors evolved to live and hunt in burrows, which many snakes still do today. The findings show snakes did not lose their limbs in order to live in the sea, as was previously suggested.
Do snakes have a slimy skin?
Snakes have dry, scaly skin while Amphibians have soft, slimy skin. Some snakes give birth to live young while all amphibians lay eggs. Reptile eggs have a leathery texture while Amphibian eggs are more jelly like and are laid in clumps.
