H. ternatanus hatch from one capsule, which differs greatly from the
results in the present study (8–45 hatchlings). The difference may
be due to two aspects: first, the whelk studied by Hamada (1974) is
a subspecies of H. ternatanus, which has evolved due to a significant
latitudinal difference between the sample collection areas; second,
they may actually be two different whelk species with the same
name; Chan (2009) reported that H. ternatanus has many synonyms,
such as Ternate false fusus, H. cariniferus, Melongena ternatanus and
Pugilina ternatana. Moreover, H. elongatus (Lamarck, 1822) shares
close morphological and geographical affiliations with H. ternatanus
(Chan, 2009).
