Diphyllobothrium latum

Broad tapeworm

Hosts

Intermediate hosts: Copepods and freshwater fish.

Identification

D. latum are long tapeworms, with an unarmed scolex. The mature adults growing up to 20m in length. The eggs are yellow and ovoid in shape.

Life Cycle

The eggs devlop in water, and hatch, releasing coracidium. These are ingested by copepods, and the coracidium develop into procercoids. The copepod is then ingested by freshwater fish. These procercoids develop into plerocercoid. The infected fish are then ingested by a defintive host.
