Iberian Water Frog (Pelophylax perezi) has been introduced in Somerset, I recollect my surprise on hearing them at Shapwick soon after the introduction, link forum discussion from 2006, 15 years after the introduction with the species identity still unknown.

Marsh Frog (Pelophylax ridibundus) were introduced into Kent in the 1930s, becoming abundant. Edible Frog (Pelophylax kl. esculentus) the fertile hybrid of the Marsh Frog (P. ridibundus) and Pool Frog (P. lessonae) also has a history of introduction.

The above paper is an essential read, it explores the issue of which species of amphibian are native, which species are extirpated. The northern clade pool frog Rana lessonae now Pelophylax lessonae is an example of a native species interpreted as an introduction.

La grenouille qui défie les frelons : une résistance au venin encore inexpliquée

Une étude japonaise révèle que la grenouille Pelophylax nigromaculatus peut capturer et manger des frelons pourtant capables de tuer de petits vertébrés en une seule piqûre.

It definitely is one. After having a look, or rather listen, I can even tell you which species it's likely based on: Pelophylax esculentus. It's only frog species here that sounds remotely like that, and is one of the most common

Meerkikker teistert Nederland: invasieve soort bedreigt inheemse amfibien
De meerkikker (Pelophylax ridibundus) heeft zich genesteld in Zuidoost-Nederland, met name in Limburg, en breidt zijn territorium uit naar Noord-Brabant, Zuid-Holland en Noord-Holland. Deze oorspronkelijk uit de Balkan en Turkije afkomstige soort, die van nature niet in Nederland voorkomt, vormt een significante bedreiging voor de inheemse amfibieënpopulaties. De introductie van de meerkikker in Nederland wordt vermoedelijk veroorzaakt door de handel in kikkers, waaronder die voor de productie van kikkerbillen. Ook de recente verkoop van exotische kikkervisjes in tuincentra kan een rol hebben gespeeld in de verspreiding van deze invasieve soort. De meerkikker gedijt goed in de Nederlandse...

Distribution and #evolution of the western European water frogs (genus Pelophylax) from Catalonia, northeastern Spain @peerj.bsky.social
Distribution and #evolution of the western European water frogs (genus Pelophylax) from Catalonia, northeastern Spain
European water frogs from the genus Pelophylax are particular among amphibians as they can produce hybrids (named kleptons) reproducing by hybridogenesis. Four klepton species have been described in Europe: Pelophylax kl. esculentus, P. kl. hispanicus, P. kl. grafi, and the putative klepton PK. While most of these kleptons originated naturally in areas where the parental species occur in sympatry, human-mediated translocations of water frogs across Europe have altered this dynamic. As a result, several Pelophylax species and kleptons are now found outside their natural ranges, posing a threat to autochthonous water frogs. Additionally, the subtle morphological differences between Pelophylax species make hybrid identification and, thus, conservation difficult. In the present study, we analyzed 423 specimens from 54 populations sampled across Catalonia and implemented a two-step molecular method to identify all species of water frogs present in Catalonia. We also examined the mitochondrial genome of the hybrid Pelophylax kl. grafi to obtain new insights into their reproductive system and spatial structure. Despite the large number of samples analyzed, only the native P. perezi and its klepton P. kl. grafi were found, with the proportion of the latter being unexpectedly high. Results showed a high misidentification rate based on morphology compared to molecular methods, indicating that identification of P. kl. grafi through morphological characters is unreliable. Furthermore, the mitochondrial DNA of hybrid specimens entirely belonged to P. perezi and showed high intra-specific variability. This suggests either a single hybridization event involving a male P. ridibundus or P. kl. esculentus and a female P. perezi, or that P. ridibundus mitochondrial DNA has been eliminated from the P. kl. grafi germline by adaptive or non-adaptive processes. This study offers new insights into the distribution and composition of the North Iberian Pelophylax hybridogenetic complex, providing comprehensive sampling across one of the main entry points of the complex into the Iberian Peninsula.
