Parasite communities of two sharks, Etmopterus granulosus (Squaliformes) and Schroederichthys bivius (Carcharhiniformes), from Southern Chile

Abstract: The purpose of this study was to analyze the parasite community of two shark species from Southern Chile considering that the shark-parasite association in the area is poorly known. A total of 24 specimens of the southern lanternshark Etmopterus granulosus, and seven specimens of the narro...

Parasite composition southern lanternshark narrowmouthed catshark Strait of Magellan Abstract: The purpose of this study was to analyze the parasite community of two shark species from Southern Chile considering that the shark-parasite association in the area is poorly known. A total of 24 specimens of the southern lanternshark Etmopterus granulosus, and seven specimens of the narrowmouthed catshark Schroederichthys bivius were collected from the Strait of Magellan during January of 2017 and 2018. We recorded a total of 87 parasites associated with the examined E. granulosus, which belonged to seven species, and 192 parasites associated with the examined S. bivius, which belonged to other seven species. The higher average of parasite abundance was in S. bivius (27.5 ± 25.5 parasites/host) compared to E. granulosus (3.5 ± 3.3 parasites/ host). A few parasites were prevalent and abundant; the nematodes Pseudoterranova sp. (41.7% prevalence; 1.46 parasites/host) and Anisakis sp. (29.2% prevalence; 1.21 parasites/host) present in E. granulosus, and the copepod Tautochondria sp. (85.7% prevalence; 9.14 parasites/host) and the nematode Proleptus niedmanni (71.4% prevalence; 14.86 parasites/host) present in S. bivius. Similitude in terms of parasite composition between the two shark species was low (14.6%), with two parasite species in common, the anisakid nematodes Pseudoterranova sp. and Anisakis sp. Thus, despite the sympatry of the two shark species analyzed in this study, the parasite composition was significantly different. The difference in parasite composition of the E. granulosus and S. bivius could be due to their evolutionary history, involving several differences in the ecology of the hosts.info:eu-repo/semantics/openAccessUniversidad de MagallanesAnales del Instituto de la Patagonia v.49 20212021-01-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-686X2021000100202en10.22352/aip202149004
