Abstract

We show in this paper that amphioxus (Branchiostoma lanceolatum) is capable of collecting sub-micron particles on its mucous filter. This is made by an endostyle in some respects simpler than those of tunicates, and that unlike the filters in tunicates, the strands of the amphioxus filter are sticky. It therefore does not act simply as a sieve.
