QUÉ SIGNIFICA CLASPERS EN INGLÉS
Clasper
En biología, un clasper es una estructura anatómica masculina encontrada en algunos grupos de animales, usados en apareamiento. Los peces cartilaginosos masculinos se forman a partir de la porción posterior de su aleta pélvica que sirven como órganos intromitentes utilizados para canalizar el semen en la cloaca de la hembra durante el apareamiento. El acto de apareamiento en algunos peces incluyendo tiburones incluye generalmente uno de los claspers levantados para permitir que el agua en el sifón a través de un orificio específico. El clasper se inserta entonces en la cloaca, donde se abre como un paraguas para anclar su posición. El sifón entonces comienza a contraer la expulsión de agua y esperma. Las quimeras masculinas tienen cepillos cefálicos sobre sus cabezas, que se cree que ayudan a mantener a la hembra durante el apareamiento. En entomología, es una estructura en insectos machos que se utiliza para sostener a la hembra durante la cópula.
