Editing Lancelet (section)

=== Habitat ===
Adult amphioxus typically inhabit the seafloor, burrowing into well-ventilated substrates characterized by a soft texture and minimal organic content. While various species have been observed in different types of substrate, such as fine sand, coarse sand, and shell deposits, most exhibit a distinct preference for coarse sand with low levels of fine particles. For instance, ''Branchiostoma nigeriense'' along the west coast of Africa, ''Branchiostoma caribaeum'' in [[Mississippi Sound]] and along the coast from South Carolina to Georgia, ''B. senegalense'' in the Atlantic Ocean on the [[Continental shelf|shelf]] region off [[Maghreb|North West Africa]], and ''B. lanceolatum'' along the Mediterranean coast of southern France all demonstrate this preference.<ref>{{Cite journal |last1=Webb |first1=J.
