“…Many of the described species lack these ascending fiber nodes, and instead have a "hymedesmoid" skeletal structure of spicules embedded directly in the basal spongin, tips up (Aguilar-Camacho & Carballo 2013;Cavalcanti et al 2018;Santos et al 2014). This variable skeletal structure may be related to the thickness of the species (Santos et al 2014). Previous molecular phylogenies of multiple loci found Eurypon to be polyphyletic Thacker et al 2013), which is also found in our updated phylogenies.…”

“…Eurypon are defined as "typically encrusting Raspailiidae with microcionid skeletal structure in which fiber nodes ascend from the basal layer of spongin" (Hooper 2002c).

Sponges are common and diverse in California, but they have received little study in the region, and the identities of many common species remain unclear. Here we combine fresh collections and museum vouchers to revise the order Axinellida for California. Seven new species are described, including representatives from one family and four genera that previously had no described species in the state. One new combination is also described, and two names are placed in synonymy with existing names, resulting in a total of 13 species; a dichotomous key to differentiate them is provided. DNA data from 10 of the 13 species is combined with publicly available data to produce updated global phylogenies for the order.

The Brazilian spongiofauna is still one of the least known worldwide, and the Northeastern region of Brazil is the one with the greatest recorded diversity. Previous studies on sponges in the Rio Grande do Norte State focused on deeper regions of the Potiguar Basin and oceanic islands, lacking any records from intertidal environments. The present study aimed to investigate the biodiversity of marine sponges from two beaches on the northern coast of Rio Grande do Norte. The specimens were collected in intertidal beachrocks of Baixa Grande and Ponta do Mel beaches (Areia Branca, RN) quarterly between August 2018 and May 2019, using the active search method for 2 hours during low tide. We identified 19 species belonging to the Demospongiae class, four taxa were considered dominant and six were considered rare according to the sampling period. Our study considerably improved the knowledge of the spongiofauna for the Rio Grande do Norte State, with six new taxa occurrences: Placospongia sp., Dysidea robusta, Haliclona (Reniera) manglaris, Haliclona (Reniera) tubifera, Haliclona (Soestella) caerulea and Amorphinopsis atlantica.
