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 Pairs of Legs Few millimetres up to 37 centimetres Two Large Poisonous Fangs, Rear Hind Legs and Antennae Variable Colours; Mainly Dark Q1n6oQipumI/Tawowda46WI/AAAAAAAADWo/jfSgyd HPn6c/s1600/centipede.jpg 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 pg?zz=1 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 eggs laid in soil or hollowed out wood Female winds body around egg mass and guards
