  • There are far more species of arthropods than there are species in all the other phylum’s (phyla) combined.  
  • They are spiders, insects, centipedes, mites, ticks, lobsters, crabs, shrimp, crayfish, krill, barnacles, scorpions and many, many others. 
  • Arthropods are cold blooded — which means, their body temperature depends on the temperature of the environment surrounding them.
