The Seris of northwest Sonora have a profound cultural tradition of molluscan interaction, applying common indigenous names to over 150 species of molluscs. The Seris used the shelled cephalaspidean Bulla gouldiana for pendant jewelry, and called the animal cacaapxom ('what fattens [something]'). The common tropical eastern Pacific Nudipleura opisthobranch Berthellina ilisima, although apparently not used, was given the common name xepenozaah ('sun in the sea'). During a 25-year study at Bahía de los Ángeles, Baja California, Berthellina ilisima was the third most common opisthobranch encountered. It exhibited an annual life cycle, with reproductive activity occurring from May to July. In contrast, the more northerly common Californian species Doriopsilla albopunctata had a seasonally earlier annual life cycle, from July to June, with reproductive behavior observed during January to April. Berthellina ilisima feeds on Demospongiae poriferans.
