=== ''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~~.

==Hosts==

+

'''Intermediate hosts''': Copepods and freshwater fish.

+

'''Definitive hosts''': Humans and fish eating mammals.

+

==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.
