“…S. Thatje (ed. ) They form vast kelp beds that provide a three-dimensional habitat structure inhabited by a diverse invertebrate and Wsh fauna (Vásquez 1992;Vásquez et al 2001;Sielfeld et al 2002;Vega et al 2005;Pérez 2006). The structure of these kelp beds is physically controlled by variations in upwelling and alternating oceanographic events such as El Niño (EN) and La Niña (LN)-the warm and cold phase of the El Niño Southern Oscillation (ENSO) Arntz et al 2006;Vásquez et al 2006).…”

“…Unconfirmed species are present in all zones and generally reflect low human population density and limited commercial fishing activity in coastal regions such as the oceanic islands and austral south zones, which limit accessibility and specimen collection. In contrast, unconfirmed species records in the north zone are more likely the result of the variability in oceanic conditions related to the El Niño southern oscillation, which affects the distribution range of tropical and sub-tropical species (Sielfeld et al, 2010), and is reflected by anecdotal records of single specimens of tropical origin. The nomenclature of some species has been updated from previous reviews; Somniosus antarcticus Whitley 1939 replaces previous records of Somniosus pacificus Bigelow & Schroeder 1944 in the south hemisphere (Yano et al, 2004); S. oligodon replaces records of Scymnodalatias sherwoodi (Archey 1921) in the Nazca and Sala y Gómez submarine ridges (Ebert et al, 2013); specimens of Squalus mitsukurii reported from Robinson Crusoe and Santa Clara islands by Pequeño (1989) and Arana (2000) may represent more than one species (White & Iglésias, 2011), and therefore the notation S. cf.…”

A review of the primary literature on the cartilaginous fishes (sharks, skates, rays and chimaeras), together with new information suggests that 106 species occur in Chilean waters, comprising 58 sharks, 30 skates, 13 rays and five chimaeras. The presence of 93 species was confirmed, although 30 species were encountered rarely, through validated catch records and sightings made in artisanal and commercial fisheries and on specific research cruises. Overall, only 63 species appear to have a range distribution that normally includes Chilean waters. Actual reliable records of occurrence are lacking for 13 species. Chile has a cartilaginous fish fauna that is relatively impoverished compared with the global species inventory, but conservative compared with countries in South America with warm-temperate waters. The region of highest species richness occurs in the mid-Chilean latitudes of c. 30-40° S. This region represents a transition zone with a mix of species related to both the warm-temperate Peruvian province to the north and cold-temperate Magellan province to the south. This study provides clarification of species occurrence and the functional biodiversity of Chile's cartilaginous fish fauna.

“…In addition, 20 years records of the catch from several fishermen associations ("caletas de pescadores") located between Chipana beach (21º20'S) and Las Machas beach (18º10'S) were included. Furthermore, information on fishes inhabiting tide pools presented by Berrios & Vargas (2000 as well as records on sublitoral fishes associated to kelp beds (Sielfeld et al 2002) were also included in the analyses.…”

El Niño induced changes of the coastal fish fauna off northern Chile and implications for ichthyogeographywere typical for sandy beaches and 14.6% for rocky shores. The shore fish community did not show major changes during and after EN events, as only a few invading species were recorded; just Umbrina xantii was found during all events considered. In order to understand the response of the fish community to ENSO events a biogeographical analyses of 721 fish species reported for neritic habitats (coastal epipelagic and benthic) distributed between 0°-57°S (Gulf of Guayaquil to Cape Horn) was made. Their distribution ranges for normal oceanic conditions were taken from the very numereous existing literature. It is concluded that the north/south migration of Panamic and Peruvian warm water fishes during EN/LN events along the north Chilean coast between 18º-23ºS, indicates that it represents a wide transition zone between the Peruvian and the Chilean ichthyogeographic provinces. Key words: ENSO, neritic fishes, northern Chile, ichthyogeographyResumen.-La franja costera de la zona norte de Chile (18º-23ºS) es habitada por numerosas especies de peces neríticos de las cuales 249 son comúnmente observadas durante condiciones normales y condiciones frías La Niña (LN). Durante El Niño (EN) la ictiofauna del norte de Chile experimenta cambios significativos a causa de la presencia de alrededor de 100 especies de peces invasores que durante periodos normales y/o fríos habitan en latitudes menores, siendo también nombrados "invasores septentrionales" y "peces trópico-ecuatoriales". Este conjunto incluye 15 familias y 86 géneros de peces. Los análisis mostraron que las especies afectadas por los EN no fueron las mismas durante los últimos tres eventos, revelando que solo las especies epipelágicas Anchoa naso, Albula vulpes, Atherinella nocturna y Scomberesox saurus stolatus fueron constantes. Frente al norte de Chile, durante los EN
