“…Jefferson and Curry (2003) reported squid beaks and fish otoliths from the families Myctophidae Gill, 1893, Argentinidae Bonaparte, 1846 and Bregmacerotidae Gill, 1872 in the stomach of a single dolphin stranded in New Jersey, United States. A recent study by Pis-Millán et al (2019) found a beak of a decapodiform cephalopod and otoliths of European hake, Merluccius merluccius (Linnaeus, 1758) (TL = ca. 10-13 cm) in two Clymene dolphins stranded in the Cantabrian coast of Spain.…”

“…The poorly known Clymene dolphin, Stenella clymene (Gray, 1850) (Cetacea: Delphinidae) is a small oceanic dolphin, endemic to tropical and warm-temperate waters of the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico (Fertl et al, 2003;Jefferson, 2018;Briceño et al, 2020 and references therein). Some unusual records of Clymene dolphins have been also registered off the northern coast of Spain (up to 43 • N) (Pis-Millán et al, 2019). In the southwestern Atlantic, records of Clymene dolphins have been reported only off the coast of Brazil, where sightings and stranded dolphins have been reported up to 30 • S (Simões- Lopes et al, 1994;Fertl et al, 2003;Moreno et al, 2005).…”

“…However, the occurrence of Clymene dolphins in the Brazilian coast may be considered as unusual (Prado et al, 2016;Costa et al, 2017;Mayorga et al, 2020). Information about the food habits of Clymene dolphin is scarce, with data obtained from very few individuals stranded or incidentally captured off the Gulf of Mexico, the northeaster coast of Brazil or the North Iberian Peninsula (Jefferson and Curry, 2003;Pis-Millán et al, 2019).…”

A Visitor of Tropical Waters: First Record of a Clymene Dolphin (Stenella clymene) Off the Patagonian Coast of Argentina, With Comments on Diet and Metazoan Parasites

The poorly known Clymene dolphin (Stenella clymene) is a small oceanic cetacean distributed in tropical and subtropical waters of the Atlantic Ocean. In this study, we report, for the first time, a vagrant individual of Clymene dolphin in Argentina (Rada Tilly) that represents the current southern-most record for this cetacean species. We provide a molecular identification of the dolphin, based on partial sequences of the mitochondrial cytochrome b gene, generated from DNA extracted from its metazoan parasites. Three prey species, namely Argentine hake, Patagonian squid and lobster krill were identified from hard pieces collected in the stomach. Seven metazoan parasite taxa (three in adult stage, one immature stage and three in larval stage) were identified using morphological and molecular data, i.e., the digenean Pholeter gastrophilus (new host record), the cestodes Tetrabothrius (Tetrabothrius) forsteri, Clistobothrium grimaldii unidentified phyllobothriid plerocercoids, the nematodes Anisakis pegreffii (new host record), Halocercus delphini and the acanthocephalan Corynosoma australe (new host record). Our study provides the first molecular exploration of the metazoan parasite diversity in delphinids from the southwestern Atlantic, and contributes significantly to understand the poorly known parasite fauna of the Clymene dolphin.

“…For example, the abundance of Bryde's whales ( Balaenoptera edeni ) increased between 2000 and 2010 in the Southern California Bight (USA), which was probably driven by prey availability [45]. Similarly, unusual sightings of Clymene dolphins ( Stenella clymene ) have been recorded on the northern coast of Spain [46], the Patagonian Coast (Argentina) [47] and the Brazilian coast [48], outside their usual habitat in the tropical waters of the Atlantic Ocean, Caribbean Sea and the Gulf of Mexico. Range shifts are believed to correlate with habitat expansion, leading to a functional feeding response of cetacean species to changes in the marine environment [40].…”

Climate change directly impacts the foraging opportunities of cetaceans (e.g. lower prey availability), leads to habitat loss, and forces cetaceans to move to other feeding grounds. The rise in ocean temperature, low prey availability and loss of habitat can have severe consequences for cetacean survival, particularly those species that are already threatened or those with a limited habitat range. In addition, it is predicted that the concentration of contaminants in aquatic environments will increase owing to Arctic meltwater and increased rainfall events leading to higher rates of land-based runoff in downstream coastal areas. These persistent and mobile contaminants can bioaccumulate in the ecosystem, and lead to ecotoxicity with potentially severe consequences on the reproductive organs, immune system and metabolism of marine mammals. There is a need to measure and assess the cumulative impact of multiple stressors, given that climate change, habitat alteration, low prey availability and contaminants do not act in isolation. Human-caused perturbations to cetacean foraging abilities are becoming a pervasive and prevalent threat to many cetacean species on top of climate change-associated stressors. We need to move to a greater understanding of how multiple stressors impact the metabolism of cetaceans and ultimately their population trajectory. This article is part of the theme issue ‘Nurturing resilient marine ecosystems’.
