Family HAMINOEIDAE Pilsbry, 1895

Introduction

A family of herbivorous species. The shell is ovoid or narrowed behind, and into which the animal can retract. Haminoeids have both radula and gastral plates, the latter generally with transverse crests of projecting elements. Most species are infaunal, burrowing through the top fine sediments of the substrate. Others are epifaunal, crawling on their algal foods. Animals that burrow are usually dull in colouration, those that crawl epifaunally are often brightly pigmented. The inner whorls of the shell in all species of this family are constantly resorbed, leaving only about one and a half whorls of shelly material to protect the animal. The parapodia are reduced to small triangular folds protecting only the neck of the animal and the anterior edge of the shell at the entry to the mantle cavity. As a general rule, haminoeids live only in the intertidal or shallow subtidal. Many species are nocturnally active. Compiled from Burn (in press).
