Glycera spp.

Max Size: Up to 14 inches, most do not reach this size
Habitat: Sediment on bottom of the river
Diet: Smaller worms and other invertebrates

Fun Facts:

  • These worms catch their prey by projecting a toothed proboscis out of their mouth
  • Copper-based venom injected into prey through the worm’s teeth immobilizes and kills the prey
  • Bloodworms undergo a metamorphosis during reproduction: their body changes to allow them to swim rapidly to the water’s surface where they release their gametes in a form of broadcast spawning, after which they die
