Description

Crassitoniella carinata has a distinctive orange-red coloured ovate-conical shell, with a wide protoconch. It is solid, with a broadly blunt protoconch and has a distinct peripheral cord. The living animal has white long tentacles, with large eyes. [2] [3] The holotype of the species measures 1.91 mm (0.075 in) in height and 1.3 mm (0.051 in) in diameter. [4] The species' shell is similar to the Australian species Crassitoniella flammea , but differs by having a uniform colour and distinct peripheral cord. [2]

Taxonomy

The species was first described by Winston Ponder in 1965, as the type species of Crassitoniella. [2] The holotype was collected from Piwhane / Spirits Bay near Cape Reinga in Northland, New Zealand, in April 1951 by Ken Hipkins. It is held by the Auckland War Memorial Museum. [5] [6]

Distribution and habitat

The species is Endemic to New Zealand. [1] The species was first documented on the east coast of the North Island as far south as the Bay of Plenty, in 1995 a specimen was first identified on the west coast of the North Island. [7] Additional specimens have been found in the waters near Manawatāwhi / Three Kings Islands. [8] C. carinata typically lives on algae. [3]
