3 Evolution Two hypotheses : 1. scutigeromorph-like (elongation) 2. geophilomorph-like (tachygenesis) Five subgroups Forefront of evolutionary studies. Fossil records of 420 million years

4 Characteristics Multiple Segments 15-191 Pairs of Legs Few millimetres up to 37 centimetres Two Large Poisonous Fangs, Rear Hind Legs and Antennae Variable Colours; Mainly Dark http://4.bp.blogspot.com/- Q1n6oQipumI/Tawowda46WI/AAAAAAAADWo/jfSgyd HPn6c/s1600/centipede.jpg http://cookislands.bishopmuseum.org/MM/MX5/5AT505_Scol- subs_RR2_GM4_MXa.jpg

5 Habitat and Population Live in damp places Found on all continents except Antarctica Have population densities around 8-65 organisms/metre squared http://farm3.staticflickr.com/2575/3784516262_61de8fe9ee_z.j pg?zz=1 http://biology.unm.edu/ccou ncil/Biology_203/Images/Pr otostomes/centipedes.jpg

6 Diet/Feeding Feed on insects, spiders, worms Larger species can eat lizards, snakes, small mammals Detect prey with antennae stun or kill with venom from fangs

7 Reproduction Sperm transfer is indirect Male constructs web from glands in posterior end Spermatophore emitted and placed in web Female picks up and places in her gonopore. 15-35 eggs laid in soil or hollowed out wood Female winds body around egg mass and guards
