FAMILY Sagittiferidae

TAXONOMY

Symsagittifera corsicae Gschwentner, 2000, Corsica, Mediterranean Sea.

OTHER COMMON NAMES

None known.

PHYSICAL CHARACTERISTICS Like other members of the Sagittiferidae family, S. corsicae bears sagittocysts, which form in and arise from the epidermis, and are used for defense and capturing prey. The needle-shaped sagit-tocysts are produced in specialized gland cells called sagitto-cytes, whose roots are surrounded by muscles. The worm contracts the muscles to eject the sagittocysts. Sym-sagittifera corsicae carries its sagittocysts on its rear ventral surface.
