Genus
Common name: Bloodworms
Scientific name: Glycera
Glycera is a genus of polychaete worms commonly known as bloodworms, named for their red coloration due to hemoglobin in their bodies. They are a popular food source for many marine fish and invertebrates in the aquarium trade. Bloodworms are benthic creatures, often found in sediment, and can be used as live, frozen, or freeze-dried food. They are known for their biting jaws, which can sometimes cause irritation if handled improperly.
