Overview

Rhytida oconnori is a species of medium-sized, air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Rhytididae. It is found in a few places in the north of the South Island in New Zealand.

Rhytida oconnori faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in New Zealand. The species' restricted distribution makes it particularly vulnerable to local extinctions from land-use changes. Introduced predators, including rats and other invasive species, pose additional pressure on this endemic land snail's already fragmented populations.
