Morfología de las espículas en las especies de la familia Didemnidae (Ascidiacea) del litoral de Cataluña e Islas Baleares

Resum

On the morphology of the spicules of the Didemnid (Ascidiacea) species from the shores of Catalonia and Balearic Islands
The morphology o£ the spicules of 17 spicule-containig species of Didemnids from Catalonia and the Balearic Islands is studied by scanning electron microscopy. The analysis shows that the morphology and the number of rays of the spicules remains fairly constant within each species. The results of this work can be used to help in the classification of samples belonging to this family, from the studied and adjoining geographical zones.
