توصيف مختصر ريخت شناسي

Small chaetognath with a firm, opaque and flexible body. Muscles are strong. Lateral fields are narrow. Width of body is of same size from head to caudal septum. Intestinal diverticula is present. Head is of normal size with an inconspicuous neck. Tail segment constitutes 25 to 29 per cent of total length of animal. Eyes are large, with pigment in a large spot formed by three branches toward centre and two shorter ones toward sides. Collarette is absent. Corona ciliata seen at from neck region, extending to about midway to ventral ganglion. Ventral ganglion is large for the size of the animal. nterior fins are slightly shorter than posterior fins and begin just behind posterior end of ventral ganglion. A rayless zone is absent and at anterior end a small part of fin has rays perpendicular to body walls. Posterior fins are triangular in shape extending to seminal vesicles with widest region at the tail segment. About two thirds of the length of posterior fin is on tail. Rayless zone is absent and in the most anterior part there is a small region with rays directed perpendicular to body walls. Distance between paired fins is only about 2.8 per cent of total length. Tail fin is long.
