=== Feeding ===
Their habitat preference reflects their feeding method: they only expose the front end to the water and filter-feed on [[plankton]] by means of a branchial ciliary current that passes water through a mucous sheet. ''Branchiostoma floridae'' is capable of trapping particles from microbial to small phytoplankton size,<ref>{{Cite journal |last1=Smith|first1=Allison J.| last2= Nash|first2=Troy R. |last3= Ruppert| first3=Edward E.|date=2000|title=The size range of suspended particles trapped and ingested by the filter-feeding lancelet Branchiostoma floridae (Cephalochordata: Acrania)| url= https://www.cambridge.org/core/journals/journal-of-the-marine-biological-association-of-the-united-kingdom/article/div-classtitlethe-size-range-of-suspended-particles-trapped-and-ingested-by-the-filter-feeding-lancelet-span-classitalicbranchiostoma-floridaespan-cephalochordata-acraniadiv/78AD799D990BE3517E0D77BD557580E0|journal=Journal of the Marine Biological Association of the United Kingdom| language= en| volume= 80|issue=2|pages=329–332|issn=1469-7769| doi= 10.1017/S0025315499001903|bibcode=2000JMBUK..80..329R |s2cid=85696980|url-access=subscription}}</ref> while ''B. lanceolatum'' preferentially traps bigger particles (>4&nbsp;μm).<ref>{{Cite journal|last1=Riisgard|first1=Hans Ulrik|last2=Svane|first2=Ib|date=1999| title= Filter Feeding in Lancelets (Amphioxus), vertebrate Biology| journal= Invertebrate Biology| volume= 118|issue=4|pages=423|doi=10.2307/3227011|issn=1077-8306| jstor= 3227011}}</ref>
