Acanthancora schmidti (Topsent, 1898) (Porifera, Poecilosclerida) primera cita para el Mar Cantábrico

Abstract

Acanthancora schmidti (Topsent, 1898) es un porífero que fue recogido por primera vez en las Islas Azores en 1895, a 349 metros de profundidad en las proximidades del Cabo San Jorge y en 1897, a 599 metros en la isla de Terceira. Inicialmente se describió dentro del desaparecido género Leptosia Topsent, 1892 pero fue ubicado finalmente en el Género Acanthancora Topsent, 1927. Este género pertenece a la Familia Hymedesmiidae, constituida por poríferos incrustantes. Contiene en la actualidad tan solo cinco especies: A. aenigma (Lundbeck, 1910), A. coralliophila van Soest, 1984, A. cyanocrypta (de Laubenfels, 1930), A. schmidti (Topsent, 1898) y A. stylifera Burton, 1959. En la presente comunicación se redescribe la especie aportando nueva información y constituye la primera cita desde la descripción original de 1898 y por lo tanto, la primera vez que se registra en aguas del mar Cantábrico, ampliándose su área de distribución. El ejemplar se recolectó en la campaña Indemares-Avilés 0710 a 128 m en las inmediaciones del Cañón de Avilés. La especie se caracteriza por ser ejemplares de pequeño tamaño, incrustantes, de superficie lisa y sin ósculos aparentes y cuyo esqueleto típicamente hymedesmioide está compuesto de acantostilos, tornotes e isoquelas espinosas. Este organismo ha sido identificado a partir de la morfología de sus espículas, con microscopía óptica y además se fotografían por vez primera con microscopio electrónico de barrido.
