Abstract (en):
The sea slugs comprise the subclass Opisthobranchia, placed within gastropods (phylum Mollusca), a group that exhibits a wide range of body forms, from shelled organisms externally similar to caenogastropods, to highly derived shell-less forms. With shell loss, many additional external structures are acquired, such as cerata, sensory tentacles, and rhinophores. These structures serve a variety of sensory, defensive, and respiratory functions (Gosliner 1994). They are mostly bilaterally symmetrical and often with parapodial lobes (Thompson 1976).
Abstract (es):
Las babosas de mar comprenden la subclase Opisthobranchia, situada dentro de los gasterópodos (phylum Mollusca), un grupo que exhibe un amplio arreglo en sus formas corporales y comprende desde organismos con concha, externamente similares a los caenogastropodos hasta una gran variedad de organismos que carecen de conchas. Estos han sufrido una detorsión que los ha llevado a la reducción o pérdida de la concha. Con la pérdida de la concha, varias estructuras adicionales externas están presentes como las ceratas, tentáculos sensoriales y rinóforos. Estas estructuras cumplen con una variedad de funciones sensoriales, defensivas y respiratorias (Gosliner 1994). La mayoría de estos organismos poseen una simetría bilateral y lóbulos parapodiales (Thompson 1976).
