Certain identification generally requires dissection followed by microscopic examination of internal features after removing the outer coat (test).

For the larger species this is often most easily accomplished with a pair of fine-pointed scissors inserted through the oral siphon; cutting with a scalpel invariably slices through the gut and gonads as well. This should be done relatively soon after collection, since, although they survive for several days in a refridgerator, once the gut is empty it is much less visible.
