AI Article Synopsis
- A dense population of the sea anemone Diadumene paranaensis was discovered at Arpoeiras Beach, near the Acaraú River in Brazil.
- The study compares the new specimens with earlier collected type material and suggests changes to the classification of the species, family (Diadumenidae), and genus (Diadumene).
- It also highlights the species' ability to tolerate high salinity and predicts a wider distribution of this sea anemone along the Brazilian coast.
Article Abstract
A dense estuarine aggregation of Diadumene paranaensis Beneti, Stampar, Maronna, Morandini & Da Silveira, 2015 associated with Rhizophora mangle L. was found at the Arpoeiras Beach, mouth of Acaraú River, Ceará, Brazilian semi-arid coast. Here, we compare biological and taxonomical traits with the type material, collected from the portuary zone of Paranaguá Bay, and propose modifications in the diagnosis of the species, as well as of the family Diadumenidae and genus Diadumene, to align with the description of our specimens. In addition, we discuss its tolerance to high salinity and predict a much broader geographic range for this sea anemone in Brazil.
