Ancilla lienardi (Bernardi, 1821) (Mollusca: Gastropoda: Olividae) da Coleção Malacológica Prof. Henry Ramos Matthews Série-B (UFC)

Abstract

The species of the Olividae family are marine, ranging from tidal range to deep water are generally found in subtropical and tropical seas and oceans on sandy substrates. Olivids are carnivorous and feed mainly on bivalves and dead animals and quickly bury themselves in the substrate.The species of this family have smooth, shiny and elongated oval shells. In Brazil, the Olividae family is represented by seven genera and forty species, among them Ancilla lienardi. This species is endemic to the North and Northeast of Brazil and is common in sandy substrate in the infralittoral region.The present research had as objective to study the specimens of Ancilla lienardi from the Malacological Collection Prof. Henry Ramos Matthews B Series of the Universidade Federal do Ceará (UFC). The shells were measured in length and width, with the aid of a precision caliper of 0.1mm.The digital worksheets and the collection logbook were also consulted to check how many lots had and the sources of the material.The Malacológical Collection Prof. Henry Ramos Matthews Series B (CMPHRM-B) has 8 batches of Ancilla lienardi with a total of 41 shells. All batches are collected in the state of Ceará in different locations. The batches with the highest number of shells is from Porto dos Barcos-Itarema-Ce (11) and the smallest number of shells is from Praia da Redonda, Icapuí-Ce (1). Through this study and based on little existing literature on the species it can be inferred that there is much to be discovered about Ancilla lienardi.
