Architectonicoidea

Situados dentro del grupo informal Heterobranchia basales, los Architectonicoidea forman un grupo de caracoles marinos, con categoría de Superfamilia, con conchas enrolladas en espiral, a menudo ornamentadas, que se categorizan como Heterobranquios por heterostrofia, la morfología de los espermatozoides y del osfradio, así como por determinadas características genéticas.

El orden Architectonicida (equivalente a la Superfamilia Architectonicoidea sensu lato) comparten las características mencionadas de ser caracoles bentónicos con la concha en espiral muy aplanada, que suelen estar pigmentados de color marrón y ornamentados. Disponen de un morro y un pie ancho y bifido, y un par de tentáculos anchos y alargados en la cabeza. El grupo tiene 3 familias a nivel mundial, todas ellas presentes en aguas europeas.
