Description

edit

The shell resembles Irenosyrinx, but with stronger sculpture with narrow, low ribs and with a paucispiral, elongate operculum, bearing such a relation to the normal species of Turris as Mohnia bears to Chrysodomus. The nucleus is terminal. [3]

Gastropods of this genus are among the largest members of the family Cochlespiridae in the Pacific Ocean, with adult shell sizes reaching up to 92 mm.

Distribution

edit

Species of this genus inhabit the Pacific Ocean, the southwestern Atlantic Ocean and the southeastern Indian Ocean; also in the cold waters off Patagonia, Tierra del Fuego, the Falkland Islands and the South Shetlands. [4]

Habitat

edit

These species are predominantly found in sublittoral and relatively deep waters. However, detailed descriptions of the specific composition of Aforia in bathyal and abyssal environments are sparse. There is limited information on the distribution of these species, and data on their anatomy are almost nonexistent. [5]
