The more recently investigated mechanism concerns the decrease in effective posterior restraint (increased leaflet slack) caused by anterior redirection of papillary muscle tension; increased length of the residual leaflet, which is relatively free to move anteriorly, unlike the coapted leaflet bodies; and interposition of the leaflets into the path of outflow with the potential to cause drag forces (pushing forces of flow) (5, 6).

Two mechanisms of burrowing are used: 1) anteriorly directed head thrusts during which the body is thrown into a number of loose curves, pushed against the walls of the tunnel to create friction, and the head is extended from a gathered position of the anterior trunk, and 2) side-to-side shovelling using the rostral scale during which the rostral scale and snout are first passively deflected by the material being shovelled aside and the snout then returns to its rest position before continuing to move in the same direction as the head.
