==Identification==
 
''T. ovis'' is a large tapeworm, usually around 1m in length.  It has numerous hooks.
 
 
 
==Life Cycle==
 
The intermediate host ingests cysticercus, which hatch in the intestine and later infect the skeletal muscle and the heart.  The definitive host becomes infected by ingestion of the intermediate host. 
 
 
 
The prepatent period for ''T. ovis'' is 6-9 months.

==Identification==
 
''T. pisiformis'' is around 2m in length, and have large scolexes and hooks.
 
 
 
==Life Cycle==
 
Infection of the intermediate host is through ingestion of the tapeworm eggs shed by the dogs.  The hatch in the small intestine of the intermediate host, they then continue to develop in the liver and the abdominal cavity.
 
 
 
The definitive host is infected by ingestion of the cysticercus.  The prepatent period of ''T. pisinformis'' is around 7 weeks.
 
*It is similar to T. hydatigena, except that the cysticerci are pea-sized and are found on the omentum of rabbits.

''T. multiceps'' are around 5cm in length.
 
 
 
==Life Cycle==
 
The intermediate host is infected via ingestion of the parasite eggs.  These eggs hatch in the small intestine.  The parasite the migrates to the spinal cord and brain via the blood stream.  The definitive host becomes infected when it eats the spinal bord, or brain of the intermediate host.

==Identification==
 
''T. serialis'' is around 0.5m, with two prominent rows of hooks.
 
 
 
==Life Cycle==
 
The intermediate host is infected through ingestion of the tapeworm egg, which is shed by the dog, which acts as the definitive host.  These develop and form cysts in the intermuscular connective tissues of rabbits, often causing a soft subdermal swelling. .  The definitive host then becomes infected through ingestion of the metacestode.

The adult is around 70 cm, and has a large scolex.
 
 
 
==Life Cycle==
 
The eggs are past in faeces, which are ingested by the intermediate host.  The metacestode matures in the intermediate host, before being ingested by the definitive host.
