==Life Cycle==
 
The eggs develop 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 definitive host.

Diphyllobothrium latum

An important cestode of humans and fish-eating mammals. They are long tapeworms with an unarmed scolex. D. latum occurs in arctic and near arctic regions. Humans act as final host, but dogs may be infected. Causes anaemia because of its avid uptake of dietary vitamin B12. Eggs release a motile larval form which develops further in aquatic copepods and ascends the food chain, from fish, to humans.
