| Summary: | [EN]: The Australian white-spotted jellyfish, Phyllorhiza punctata had not been previously recorded in the Northeast Atlantic Ocean. Here, we present the first record of this species in the southwestern Atlantic coast of Spain, Cadiz. Particularly, ten specimens including juveniles and adults were collected in August and October 2018 during five field surveys conducted in a tidal creek (Rio San Pedro), communicated with the Bay of Cadiz. The origin of the organism is unknown although long-distance transport of polyps attached to ship hulls or expansion of jellyfish aquarium exhibitions can be considered as possible pathways of invasion. Future observations are required to assess if P. punctata has established a stable population in the region. [FR]: Premier signalement de Phyllorhiza punctata (Cnidaria: Rhizostomae: Mastiglidae) dans l'océan Atlantique nord-est. La méduse australienne, Phyllorhiza punctata n'a encore jamais été signalée dans le nord- est de l'océan Atlantique. Nous présentons ici le premier signalement de l'espèce sur la côte atlantique au sud- ouest de l'Espagne, à Cadix. Dix spécimens, comprenant des juvéniles et des adultes, ont été trouvés en août et octobre 2018, lors de cinq échantillonnages dans le chenal de marée du Rio San Pedro, communiquant avec la Baie de Cadix. Le transport à longue distance de polypes attachés aux coques de navires ou l'augmentation d'expositions d'aquarium de méduses sont des voies possibles d'invasion. Des observations futures seront nécessaires afin de montrer si une population de cette méduse s'établira de façon pérenne dans ce nouvel habitat. The Spanish Ministerio de Ciencia, Innovación y Universidades funded this research under grant number CTM2016-75487-R for the project MED2CA.AEN was financially sustained by a PhD fellowship from the MED2CA project. |
