The morphology of ''S. papillosus’’ is the same as that of the ‘’S. westeri’’. The eggs hatch inside the host and so L1 larvae are released with the faeces.

====Life Cycle====

The life cylce of ''S. papillosus'' is typical of [[:Category:Rhabditoidea|strongyloides]] species with both parasitic and free living cycles. As adults animals will become immune to infection the primary method of infection for young animals is through the milk of the dam, this still involves only females as males are only present in the environment as 'free-living' nematodes.
