Lancelet

Small lancelet (cephalochordate) shown in side view as a slender, laterally compressed, blade-shaped translucent body tapering to pointed ends. The body is pale beige, cream, sandy, pinkish-beige, light gray, or translucent light tan, with faint repeating segmented muscle bands or V-shaped myomeres visible along the sides. It has a simple pointed snout with no distinct head, jaws, paired fins, or prominent paired eyes. Low continuous fin folds or narrow fin-like margins run along the dorsal edge and continue around the tail, with a slight ventral fin fold or fin-like edge along the belly, creating a streamlined primitive chordate appearance.
