Both centipedes and millipedes belong to the multi-legged creature group but have many differences that set them apart. The biggest centipede vs. millipede difference lies in their appearance. A centipede has its legs positioned outwards like claws while the legs of a millipede are positioned directly beneath its body, towards the ground.
Let’s take a closer look at millipede vs. centipede:
|Body||Both centipedes and millipedes have segmented cylindrical bodies|
|Antennae||Centipedes have longer antennae than millipedes|
|Legs||Centipedes have outward positioned legs while millipedes do not|
|Class||Centipede class is Chilopoda while the class of millipede is Diplopoda|

Millipede and Centipede FAQs
What’s the Difference Between a Centipede and a Millipede?
The visual difference between centipedes and millipedes is the direction of their legs. Where a centipede’s pair of legs are bent outwards like claws, millipede legs are under their body and carry it through.
Are Millipedes Carnivores?
No. Millipedes feed on decaying organic matter only.
Which is More Dangerous, a Millipede or a Centipede?
Centipedes are more dangerous than millipedes since a few different types of centipedes are known to cause fatality even to humans. However, all types of millipedes are harmless to humans.
Do Centipedes Eat Millipedes?
No, centipedes do not eat millipedes, generally. But in case they spot a hurt or almost dead millipede, they might eat them.
Why You Should Never Squish a Centipede?
Centipedes excrete venom when squished. Where it is harmless to most humans, people allergic to insect bites would need medical attention, immediately. Larger centipedes may puncture human skin with their claws. The bee sting-like bite can cause burning, itching, or other similar irritations.
What is the Most Dangerous Centipede?
A giant centipede, scientifically known as Scolopendra Subspinipes, is the most dangerous centipede with its venom strong enough to cause heart attacks, kidney damage, to name a few. Many deaths have been reported owing to the giant centipede’s bite. (Ref. 3)
Why Can’t Centipedes have 100 Legs?
Centipedes do not have an even number of leg sets. And to have 100 legs, a centipede must have 50 pairs of legs. Thus, no centipede can have 100 legs for their pair of legs are always an odd number.
What do Centipedes Hate?
Centipedes hate strong natural smells like that of peppermint. Peppermint oil not only drives them away but burns them instantly.
What do Millipedes Hate?
Millipedes hate the dominating smells like that of peppermint or tea-tree. The essential oils from these two plants are great repellants for millipedes.
Are Millipedes Faster than Centipedes?
No. Due to their short legs, millipedes are rather slower.
The Final Words
The physical characteristics of a millipede are different from a centipede with the former having their legs positioned downwards while the latter having them positioned outwards. You can observe this physical difference clearly from the images of centipedes and millipedes. Millipede or centipede difference also lies in their class. Millipedes belong to the Diplopoda class whereas the centipede class is Chilopoda. Also, centipedes are dangerous for humans while millipedes are not.
