| Summary: | Global changes are currently underway, resulting in the discovery and introduction of new species in unexpected locations. One notable case involves the Indo-Pacific species Pseudechidna brummeri, which was observed and captured on film during a nocturnal dive in Portugal. This situation raises the question: How did this species come to inhabit this area? Two primary explanations appear plausible: a) The species may have been introduced through ship ballast water, a common pathway for the unintentional transport of aquatic organisms. Given the proximity of a large port, this possibility gains significance. b) Alternatively, the species could have originated from a home aquarium, a factor that remains poorly understood. The potential for species to escape or be released from aquariums into natural ecosystems is an area that requires further investigation. Another pertinent question to consider is whether there is only one individual of this species or if there are more individuals present? This study had the support of national funds through Fundação para a Ciência e Tecnologia, I.
