The terminal '''proglottid''' forms approximately half the total length. The proglottids are shed in the faeces. The '''oncosphere''' are capable of surviving in the environment, for up to two years. They are then ingested by the intermediate host e.g. the sheep, where they penetrate the gut lining.

They are then ingested by the intermediate host e.g. the sheep, where they penetrate the gut lining.
The oncosphere then travels to the liver and the lungs, where the hydatid then begins growth. This is a slow process taking around 6-12 months, and the cysts are capable of growing up to 20cm in length.

The definitive host e.g. the dog, then ingests the offal of the intermediate host, and the life cycle continues.

The prepatent period of ''E. granulosus'' is 6-7weeks. No more than one gravid segment is passed by each tapeworm each week. This species therefore has a low biotic potential.
