Live nematosomes are capable of subduing brine shrimp (Artemia salina). (See also Additional file 4.) a Aggregates of nematosomes (arrowheads) are attached to subdued brine shrimp. b Higher magnification reveals the presence of two spent cnidocysts (arrows) protruding from the exoskeleton of the shrimp. c A high-magnification image of an isolated nematosome reveals two spent cnidocysts (white arrows). Black arrow indicates a spent cnidocyst in another focal plane. All scale bars represent 10 μm unless otherwise specified
