Tamoya haplonema (Cnidaria: Cubozoa) from Uruguayan and adjacent waters: oceanographic context of new and historical findings

Abstract

New records of the cubozoan jellyfish Tamoya haplonema in Uruguayan waters are reported together with historical records for the region, and associated with the oceanographic conditions at the moment of the finding. Occurrences of the species are mainly associated with positive Sea Surface Temperature Anomalies especially during summer months when the intrusion of warm oceanic waters to the Uruguayan coastline is stronger. This was particularly strong during 2012-2013, when a dry period enhanced this scenario. This species is the only cubozoan present in Uruguay, with a sporadic occurrence and so far has no appreciated negative effects on public health. However, from observed increasing frequency of positive temperature anomalies it would be reasonable to predict a future southward shift in the latitudinal distribution of T. haplonema. In this context, occurrence of this toxic species along Uruguayan coastal waters must be considered with particular attention to the potential negative impact on tourism and on general public health.

Medusae (Scyphozoa and Cubozoa) from southwestern Atlantic and Subantarctic region (32 60S, 34 70W): species composition, spatial distribution and life history traits

“…Although members of the Class Cubozoa are found south of 35°S in Australia and New Zealand (Southcott, 1956(Southcott, , 1958Kramp, 1961Kramp, , 1970, they were rare at the same latitudes in the southwestern Atlantic. Leoni et al (2016) stated that attention will have to be paid due to the potential expansion of Tamoya haplonema southwards and its potential impact on tourism and general public health. However, the current evidence (i.e., only sporadic findings) indicates that this species is so far rare in this region.…”

“…The first record of a cubomedusa from the study area was made by Barattini & Ureta (1961, sometimes dated as 1960 as an uncommon occurrence of Carybdea atlantica. However, it has been considered that this record is dubious and possibly conspecific with T. haplonema (Mianzan et al, 1988;Mianzan & Cornelius, 1999;Pastorino, 2001;Leoni et al, 2016); thereby, it has been omitted in this study. Three new records (one specimen each) are reported in the present study slightly extending northwards the previously known range within the boundaries of the study area (Fig.…”

First records of jellyfish (Cubozoa, Scyphozoa), siphonophores (Hydrozoa), and ctenophores (Tentaculata) in the Lobos-Tuxpan Reef System, Mexico

“…Distribución geográfica. Uruguay (Leoni et al, 2016); Brasil (Barba et al, 2016); noreste del Golfo de México (Segura-Puertas et al, 2009); suroeste del Golfo de México: Sistema Arrecifal Veracruzano (Ocaña-Luna et al, 2015).…”

“…Comentarios. Las características morfológicas descritas de T. haplonema referentes a la umbrela y pedalia, así como a la presencia de verrugas de nematocistos, coinciden con las descripciones de Mayer (1910), Pastorino (2001), Morandini et al (2005), Bentlage y Lewis (2012) y Leoni et al (2016). Por lo anterior, el presente resultado confirma la presencia de T. haplonema en el suroeste del golfo y en el SALT.…”

First record of association between <i>Tamoya haplonema</i> (Cnidaria: Cubozoa) and stromateid fish, with a review on interactions between fish and cubozoan jellyfishes

“…In order to identify the jellyfish as T. haplonema, we used the identification key provided in Morandini et al (2005), which indicates that this is the only cubozoan with four pedalia and one tentacle per pedalia reported for Brazilian waters. T. haplonema is likely distributed throughout Central and South America s Atlantic coast, from the Caribbean Sea in the north, south to Uruguay (Leoni et al 2016;S. N. Stampar, pers.…”
