| Comments | The nematocyst capsule has a wall consisting of small disulfide- linked collagen-like molecules, called mini-collagens [2–4]. It is filled with a matrix of charged ?-glutamate polymers and cations [5] generating a high internal pressure (15 MPa) that drives discharge [4,5]. [numbers in parentheses are refs in article].
