Fall velocity measurements were conducted with either living or dead postlarvae which were allowed to sink into a 2&nbsp;m long Plexiglas cylindrical chamber. Five groups of increasing size-classes were tested ranging from the very first benthic stage (1&nbsp;mm&nbsp;&lt;&nbsp;Tube<sub>length</sub>&nbsp;&lt;&nbsp;2&nbsp;mm: membranous tube present accounting for more than 75% of the total tube length) to older stages (6&nbsp;mm&nbsp;&lt; Tube<sub>length</sub>&nbsp;&lt;&nbsp;10&nbsp;mm: membranous tube absent). We used these results to propose the first estimates of dispersal distances by several post-larval stages secreting mucus or sinking passively through the water column. Experiments were carried out in the HYCOBENTHOS flume to determine values of critical shear velocity (<i>u</i>                <sub>*c</sub>) inducing bedload transport and further resuspension of postlarvae of increasing sizes. The influence of mucus secretion by recruits on their ability to stay or quit a &#8216;suitable&#8217; substratum was investigated by using either living or dead individuals. Results showed that: (a) the ability to secrete mucus rapidly is limited to the younger stages; (b) fall velocity of postlarvae is drastically lowered by mucus secretion (5 orders of magnitude) and is higher for the older stages; (c) dead recruits behave similarly to &#8216;passive&#8217; recruits; (d) horizontal distances of drift dispersal may be considerable (up to 800&nbsp;m for a single 22&nbsp;min trip); (e) mucus secretion may be used by the postlarvae to anchor themselves to the substratum. Cost-benefit of using the mucus secretion as a tool for recruitment and the related spatial scales are discussed.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"How to leave or stay on the substratum when you can’t swim?
