The identity was verified using both morphological genetic criteria. In this study, we compile information global occurrences these two deep–see species, they are uncommonly observed shallow waters Iberian Peninsula. It highlights importance conducting further research to understand full range species inhabiting waters. presence can provide insights into environmental conditions specific habitats within Cádiz, as often associated with particular ranges oceanographic features.
