CHE SIGNIFICA CLASPERS IN INGLESE
clasper
Nella biologia, un clasper è una struttura anatomica maschile trovata in alcuni gruppi di animali, utilizzati in accoppiamento. I pesci cartilaginei maschi hanno claspers formati dalla parte posteriore della loro pinna pelvica che fungono da organi intromessi usati per canalizzare il seme nella cloaca femminile durante l'accoppiamento. L'atto di accoppiamento in alcuni pesci tra cui squali include di solito uno dei claspers sollevati per consentire l'acqua nel sifone attraverso un orifizio specifico. Il clasper viene quindi inserito nella cloaca, dove si apre come un ombrello per ancorare la sua posizione. Il sifone comincia quindi a contrattare l'espulsione di acqua e spermatozoi. Le chimiche maschili hanno cephalic claspers sulle loro teste, che sono pensati per aiutare a tenere la femmina durante l'accoppiamento. In entomologia, è una struttura negli insetti maschi che viene utilizzata per tenere la femmina durante la copulazione.
