Abstract: The hunting tactics of lemon sharks, Negaprion brevirostris, are described from underwater and cliff-top observations in the Fernando de Noronha Archipelago, western equatorial Atlantic, Brazil. Two main tactics were observed in the shallow waters of sandy beaches and reefs environments: (i) "substrate inspection" of crevices and holes over rocky and reef bottoms, and (ii) "sardine blitz", which refer to striking schools of fishes (mainly sardines) in the surf zone. The first tactic was restricted to juveniles… Show more

“…A great part of the main island (60-70%) and its insular shelf of 50 m isobaths constitute a MPA, where boat traffic, diving, and scientific research are regulated and fishing is prohibited. The remaining portions of the main island and its coastline constitute an Environmental Protection Area (EPA) designated for sustainable use with a local population of about 3,000 people (Garla et al, 2015;2017). Rocky faces and extensive calcareous algae barriers characterize its southern and southeastern shores.…”

“…The biology and ecology of batoids is vastly understudied (e.g., Smith, Merriner, 1985;Ebert, Cowley, 2003;Shibuya et al, 2012;Last et al, 2016) and consequently ~40% of known (~50% of evaluated) species of batoids are listed as DD in the IUCN Red List (Last et al, 2016;Martins et al, 2018;IUCN, 2019). The scarcity of ethological studies focusing on the feeding aspects of elasmobranch behavior is due, in part, to the inherent difficulty of observing predatory behaviors under natural conditions (Motta, 2004;Garrone-Neto, Sazima, 2009;Shibuya et al, 2012;Garla et al, 2017).…”

“…To analyze the potential presence of symbiotic luminescent bacteria in the megamouth shark tissues, fluorescence in situ hybridization (FISH) targeting specific bacterial RNA was performed on the suspected luminous zones (i.e. white band, teeth membrane and back of the throat [1,2,4,7,12,33,34]) from specimens captured in 2011, and 2017 ( Table 1). Pieces of M. pelagios skin tissue previously preserved in formalin were bathed in sterilized phosphate buffer saline (PBS) with increasing concentrations of sucrose (10% for 1 h, 20% for 1 h and https://doi.org/10.1371/journal.pone.0242196.g002…”

“…Indeed, historical records indicate that it shelters at least 25 elasmobranch species (Soto, 2001; Garla and Garcia 2008). The use of FNA as a nursery habitat was reported for at least three shark species: Carcharhinus perezi, Ginglymostoma cirratum , and Negaprion brevirostris (Garla et al, 2005, 2009), which have been well-studied by acoustic telemetry and underwater observations (Garla et al, 2005; 2009; 2017a; 2017b). Nonetheless, habitat use and the diversity of migrating elasmobranchs species in the region are not fully understood, as well as the possibility of the site representing a nursery area for other species (Aguiar et al, 2009, Bucair et al, 2021).…”
