ABSTRACT
This paper presents a thorough literature review of the sharpnose sevengill shark Heptranchias perlo (Bon-
naterre, 1788) in the Mediterranean Sea, creating a database with information on its distribution. Moreover, it
provides some biological information on a female specimen of this rare and near threatened shark, caught during
experimental sampling in the Myrtoon Sea, southwestern Aegean archipelago, Greece. The aim of this study is to
provide a synopsis of the existing information on the species in the Mediterranean Sea for future updates of the
assessments of the species conservation status in this area.
Key words: elasmobranchs, diet, fecundity, Mediterranean distribution
REVISIONE DELLO SQUALO MANZO HEPTRANCHIAS PERLO (CHONDRICHTHYES:
HEXANCHIDAE) IN MEDITERRANEO: DATI STORICI E RECENTI
SINTESI
L’articolo presenta una revisione approfondita della letteratura inerente lo squalo manzo Heptranchias perlo
(Bonnaterre, 1788) nel mare Mediterraneo, creando una banca dati contenente informazioni sulla sua distri-
buzione. Fornisce inoltre alcune informazioni biologiche su un esemplare femmina di questa rara specie, quasi
minacciata, catturato durante un campionamento sperimentale nel mare Myrtoon, arcipelago dell’Egeo sud-occi-
dentale, in Grecia. Lo scopo di questo studio è fornire una sinossi delle informazioni esistenti sullo squalo manzo
nel Mediterraneo per futuri aggiornamenti delle valutazioni dello stato di conservazione delle specie in quest’area.
Parole chiave: elasmobranchi, dieta, fecondità, distribuzione in Mediterraneo
