Genetic diversity and population structure of two South American marine gastropods,Crepipatella dilatataandC. fecunda(Gastropoda: Calyptraeidae): Distinct patterns based on developmental mode

“…• 31 S), and Quempillén (41 • 52 S) C. dilatata and C. fecunda are sympatric, a situation in which C. dilatata forms less abundant populations (Gallardo 1979). C. dilatata also occurs on the southwestern Atlantic coast at Puerto Madryn (Argentina).…”

“…From a morphological point of view, C. dilatata and C. fecunda are indistinguishable as adults, being recognized only on the basis of some key traits in their development (Gallardo 1979;Véliz et al 2003, Collin et al 2007. C. dilatata exhibits intracapsular development with embryos that consume uncleaved nurse eggs, and hatch as crawling juveniles with a shell length of about 1100-1200 µm.…”

“…C. dilatata exhibits intracapsular development with embryos that consume uncleaved nurse eggs, and hatch as crawling juveniles with a shell length of about 1100-1200 µm. On the other hand, C. fecunda exhibits pelagic development, embryos do not consume nurse eggs, and they hatch as planktotrophic larvae at a size of 400-500 µm (Gallardo 1977(Gallardo , 1979Chaparro et al 2002;Véliz et al 2003;Collin et al 2007). …”

“…Marine gastropods of the genus Crepipatella (Lesson, 1830) are among the most well-studied species of the family Calyptraeidae (Gallardo 1977(Gallardo , 1979Collin 2003;Véliz et al 2003;Chaparro et al 2005;Collin et al 2007), and recent studies indicate that there are five valid species: C. dilatata (Lamarck, 1822), C. capensis (Quoy & Gaimard, 1833), C. dorsata (Broderip, 1834), C. lingulata (Gould, 1846), and C. fecunda (Gallardo, 1979). Two of these species, C. fecunda and C. dilatata, inhabit rocky shores along the Chilean and Argentinean coasts.…”

Differences in feeding adaptations in intertidal and subtidal suspension-feeding gastropods: studies on Crepidula fornicata and Crepipatella peruviana

“…The closely related calyptraeid gastropods Crepidula fornicata (native to the east coast of North America) and Crepipatella peruviana (formerly Crepipatella fecunda, native to the Chilean coast) live both intertidally and subtidally (Gallardo 1979;Collin 2003;Diederich and Pechenik 2013). These gastropods eat by collecting particles from the water using their modified gill (ctenidium) and transporting those particles to a food groove, where they are concentrated, directed to the mouth (via the food groove in the neck), and ingested .…”
