Eatoniella globosa is a species of marine gastropod mollusc in the family Eatoniellidae.[1] It was first described by Winston F. Ponder in 1965. It is endemic to the waters of New Zealand.

Description

Eatoniella globosa has a thin, fragile pinkish shell. The holotype measured 1.15 mm by 0.8 mm,[2] and has a similar appearance to Eatoniella notalabia.[2]

Distribution

Corallina sp. red seaweeds, which have been identified as common habitats for Eatoniella globosa

The species is endemic to New Zealand.[1] The holotype was collected by K. Hipkins in 1949 from Piwhane / Spirits Bay, on the Aupouri Peninsula in Northland.[3] Since 1965, the species has been known to appear to the north and north-east of the North Island.[2] In 2005, a specimen of Eatoniella globosa was found off the coast of Raglan, extending its known range to the west coast of the North Island.[4] Rare specimens have been found in the Tamaki River of Auckland.[5]

Eatoniella globosa has been shown to live almost exclusively on a species of red Corallina seaweed.[6]
