“…Por otra parte, las diferencias observadas en la disposición y arreglo estructural de la línea lateral anterior, en las tres especies de narcínidos, corresponden a un mayor número de ramificaciones de los canales infraorbital y supraoccipital de N. entemedor y la presencia de un menor número en N. vermiculatus. El número de ramificaciones y, en particular, la presencia de una línea lateral con canales supraorbitales e infraorbitales, sumamente ramificados en su sección anterior, de acuerdo con diversos autores (Kalmijn, 1974;Muruska & Tricas, 1998Maruska, 2001;Shibuya, Zuanon, Araújo, & Tanaka, 2010;Marzullo, Wueringer, Jnr, & Collin, 2011;Kempster et al, 2012;Sáez, Lamilla, & Pequeño, 2014), está en relación a la búsqueda de alimento y la detección sensorial de los movimientos de las masas de agua de su entorno.…”

Description and comparison of the lateral line of three species of electric rays of the genus Narcine (Torpediniformes: Narcinidae). This study describes the composition and structural arrangement of the lateral line system of three electric ray species (Narcine bancroftii, N. entemedor and N. vermiculatus). All three species showed the supraorbital (SO), infraorbital (IO), hyomandibular (HYO) and posterior lateral line (PLL) canals, less branched compared to other batoids. Narcine entemedor differs from its congeners by the extensive branching of the SO and IO canals, which converge in the inter-orbital region; in N. vermiculatus these canals present a similar condition, but are less branched. In contrast, N. bancroftii has divergent canals (directed outwards from the inter-orbital region). HYO canals are located on the periphery of the electric organs in these species; in N. bancroftii the branches extend towards the posterior region, whereas in the other species are reduced (N. entemedor) or almost absent (N. vermiculatus). The PLL is curved and projected towards the urostyle, it also shows a large number of ramifications, except in N. vermiculatus. Information about the LL canal system arrangement and pore number in Narcine can be useful for the taxonomic distinction of its species, as it has been corroborated in other Torpediniformes. Rev. Biol. Trop. 66(2): 586-592. Epub 2018 June 01.

Longnose skates may have a high intrinsic vulnerability among fishes due to their large body size, slow growth rates and relatively low fecundity, and their exploitation as fisheries target-species places their populations under considerable pressure. These skates are found circumglobally in subtropical and temperate coastal waters. Although longnose skates have been recorded for over 150 years in South America, the ability to assess the status of these species is still compromised by critical knowledge gaps. Based on a review of 185 publications, a comparative synthesis of the biology and ecology was conducted on two commercially important elasmobranchs in South American waters, the yellownose skate Zearaja chilensis and the roughskin skate Dipturus trachyderma; in order to examine and compare their taxonomy, distribution, fisheries, feeding habitats, reproduction, growth and longevity. There has been a marked increase in the number of published studies for both species since 2000, and especially after 2005, although some research topics remain poorly understood. Considering the external morphological similarities of longnose skates, especially when juvenile, and the potential niche overlap in both, depth and latitude it is recommended that reproductive seasonality, connectivity and population structure be assessed to ensure their long-term sustainability.

“…Infraoribital and supraorbital canals from the dorsal region present a higher ramification than ventral, since innervation patters influence in the sensibility of the system and provide information on the mechanisms of peripheral processes, by presenting an abundant ramification in the canals of the lateral ventral line, mainly in the hyomandibular, infraorbital and supraorbital, this indicates an association with the search of feed (Maruska and Tricas, 2004). Also, the close relation between the canals of the dorsal region and the detection of the water movements to obtain sensorial information of its environment (Maruska, 2001;Maruska andTricas, 1998, 2004;Shibuya et al, 2010;Marzullo et al, 2011;and Sáez et al, 2014).…”
