Research Abstract

We described the neuroanatomy of the vestimentiferan tubeworm Lamellibrachia satsuma and revealed the unique neuroanatomical structures, which are not present in their relatives. We found a method for larval settlement in Osedax japonicus, observed its development, and established a multi-generation culture system.
