  1. Chilopoda Bio 1123 SorenBondrup-Neilsen Evan Carr Kinnear, Tyler Gouthro, Erika De winter, Daniel Grenon

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

  3. Characteristics http://4.bp.blogspot.com/-Q1n6oQipumI/Tawowda46WI/AAAAAAAADWo/jfSgydHPn6c/s1600/centipede.jpg http://cookislands.bishopmuseum.org/MM/MX5/5AT505_Scol-subs_RR2_GM4_MXa.jpg 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

  4. 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.jpg?zz=1 http://biology.unm.edu/ccouncil/Biology_203/Images/Protostomes/centipedes.jpg

  5. 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

  6. 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
