    used for gas exchange & feeding

  • 5 hearts

    how many hearts does annelids have

  • hemoglobin

    pigment present in annelids blood

  • single-loop system

    circulatory system used in annelids because the blood travels only in one direction

  • chlorocruorin

    some species have respiratory pigment in their blood plasma

  • deposit feeders

    lie in the bottom & extract organic matter from sediments or water
