Eatoniella smithae is a

mollusc in the family Eatoniellidae.[1] First described by Winston Ponder in 1965, it is endemic to the waters of New Zealand, and is one of the most common marine species found around Stewart Island
.

Taxonomy

The species was first identified as Eatoniella (Dardanula) smithi by

Latin gender ending, and the spelling Eatoniella smithae is now preferred.[1]

Description

Eatoniella smithae has five whorls, with a colour varying from uniformly dark purple-grey to pure white. The holotype measured 2.2mm by 1.3mm.[2]

The species has a similar shell to Eatoniella olivacea, but can be distinguished by its taller length and paler colour.[2]

Distribution

The species is endemic to New Zealand.[1] The holotype was collected in September 1947 by Elsie Smith from Halfmoon Bay, Stewart Island.[4] The species is found around Stewart Island, the lower South Island, Fiordland and the West Coast as far north as Haast.[5][6][2] The species has also been identified on the Chatham and the Auckland islands.[2][7]

It is typically found on low-tide algae, and can thrive in deep water.[2] The species appears to replace Eatoniella olivacea at Stewart Island.[2] The species is one of the most commonly found in the Benthic zone of the coast of Stewart Island.[8]
