Abstract
Recently, the neuronal classification of the ivory shell Spotted Babylon, Babylonia areolata, was
readily demonstrated. Regarding its importance as marine economic molluscan species, the

attempt to understand the neuroendocrine regulation is necessary. This study firstly demonstrated
the neurosecretory cells as well as the existence and distribution of the egg-laying hormone
(ELH)-like peptide in the central nervous system (CNS) and ovary of the B. areolata. The
neurosecretory cell was characterized by the cytoplasmic purple dot-like structure as stained by
the Gomori’s paraldehyde fuchsin. Using the anti-abalone (a) ELH, we detected the aELH-likepeptide in neurons (Nr) and neurosecretory cells (Ns) of all ganglia including the cerebral,
pleural, parietal, pedal and buccal ganglia. The aELH-like peptide was also present in the
neuropil of each. It was noted that not all Ns presented the aELH-like peptide. In the ovary, the
aELH-like peptide was slightly detected in early developing oocytes and strongly detected in late
developing oocytes and follicular cells. This study firstly reported the evidence of ELH-like
peptide in the CNS and ovary of the B. areolata. The molecular cloning as well as to investigate
the function of ELH in this species is needed as it will be beneficial for future applications in
aquaculture.
