PotentialCoryphellaTrilineataCryptic Species at FHL: an observational study using external morphology and SEM

Abstract

Methods: 11 C. trilineata specimens were collected off the docks at FHL

The external morphology of each was examined under dissection scope

Attempted to remove radula of each by dissecting with a needle

Proved very difficult to move such tiny structures between surfaces

Compare and contrast external morphology with radular morphology

Ideally use this information to determine if any cryptic species are present

A few samples have also been sent in for barcoding
