Rhabdus rectius : ウィキペディア英語版 | Rhabdus rectius
''Rhabdus rectius'' is a species of scaphopod, a small marine mollusc native to the coast of central California whose shell, like that of all the members of its order, resembles a tusk, hence the common name, "the tusk shells". ''R. rectius'' is a generalist carnivore found living in shallow silty and sandy substrates. Aside from the usual diet of foraminiferans, it also eats sediment and fecal pellets. It has a thin, straight shell which becomes fragile when dehydrated. Some adult specimens are more than long, and have a diameter of about 6 mm. ==References==
