7. *Milli means 1000 and
*centi means 100.
* Pede means foot.
* They don’t really have that many
though.
*Fossils prove they have been around for
a very long time.
*Millipedes protect themselves by curling
into a ball and spraying hydrocyanic
acid.
*Some centipedes glow in the dark.

8. Kingdom – Animialia
Phylum – Anthropoda Jointed legs and an exoskeleton
Subphylum - Myriapoda “Many-footed” with a two
segmented body
*Class Chilopoda (centipedes “100 feet”)
 
*Class Diplopoda (millipedes “1000 feet”)  
*Class Pauropoda (pauropods, pauropodans, and
progoneates)  
*Class Symphyla (pseudocentipedes and symphylans

9. *Class Chilopoda
(centipedes “100
feet”)
* It has a flat,
segmented body with a
pair of legs on each
segment.
*have a head bearing
eyes

11. *Class Diplopoda (millipedes
“1000 feet”)
*It has two pairs of legs on
each body segment.
*The Greek translation is
“double footed”.

13. *Class Pauropoda
(pauropods, pauropodans,
and progoneates)
*Pauropods are a small (less
than 5 mm), eyeless, pale
terrestrial invertebrate with
eleven segments and nine
pairs of legs.
*Latin and Greek translate
into
*“small-footed.”

15. *Class Symphyla -
(pseudocentipedes and
symphylans)
*small, blind, fast-
running.
* centipede like animals.

17. RepRoduction MethodRepRoduction Method
Both the centipede and
millipede have separate sexes.
The female lays eggs which
are fertilized sexually by the
male.
Some species lay the eggs in
a "nest" where they are guarded
by the female.
Others lay one egg at a time
and then leave it.

18. *A spermatophore is a gelatinous packet of
sperm.
*Sperm transfer through mating.

19. *Millipedes are herbivores mainly
eating dead vegetation.
*Centipedes are carnivores. Their
first pair of legs inject venom to
kill prey. They feed on insects,
earthworms, and slugs. They also
eat dead vegetation.
*The digestive system is a gut that
runs from the mouth to the anus.
*The gut is lined with a protective
outer covering called a chitin,
that is shed every so often.

20. *(centipedes) have their first pair
of walking legs modified into claw
like .
*(millipedes) have each pair of
segments fused together, resulting
in two pairs of legs per segment.
*numerous legs requires a degree of
rhythmic movement
*Segment and leg length determine
the basic gaits, which may be
modified to allow rapid escape or
slow soil penetration.
*Movement is characterized by a
metachronal wave-like rhythm.
*“Crawling”
