Colour. Yellow alive and light beige in ethanol.
Description. Specimens of this species have a clathroid body formed by irregular and loosely anastomosed tubes (Figure 5A; specimen probably contracted) and oscula spread through the cormus, without water-collecting tubes. No cells with granules were found. Aquiferous system asconoid.
Skeleton. The skeleton is disorganised and composed of only one category of triactine (Figure 4B).
Spicules (Table 5). Triactines are regular (equiangular and equiradiate). Actines are cylindrical and undulated near the tips, which are predominantly rounded, however, sometimes they can be blunt (Figure 5C). Size: 65.0– 80.0/5.0 µm.
*From Solé-Cava et al. (1991).
Ecology. This sponge was found in light protected habitats, such as crevices, and at the entrance of a semi-dark cave, attached to Carijoa sp.
Remarks. The specimens from Martinique present the same morphological characteristics of the Brazilian specimens of Clathrina aurea, including spicule measurements (Table 5). In our phylogenetic tree (Figure 15), the specimens form a clade with 100% bootstrap. Within this clade, the individuals from Martinique are separated from the Brazilian ones with only 0.2% of p-distance, a distance considered to be intraspecific for Clathrina (Rossi et al. 2011).
Clathrina aurea is a widespread species in the Western Tropical Atlantic. It was originally described from Arraial do Cabo (Rio de Janeiro, Brazil) (Solé-Cava et al. 1991) and later it was also found in other regions of the Brazilian coast, such as Fernando de Noronha (Muricy & Moraes 1998), Cagarras Archipelago (Monteiro & Muricy 2004), Ilha Grande Bay (Vilanova et al. 2004), São Paulo (Lanna et al. 2007), Potiguar Basin (Lanna et al. 2009; Arvoredo Archipelago (Padua et al. 2013, 2017), and Abrolhos Archipelago (Azevedo et al. 2017). In 2015, it was reported from Peru (Azevedo et al. 2015) and in 2017 from Martinique (Pérez et al. 2017).
Geographical distribution. Brazilian Coast (from São Paulo State up to Rio Grande do Norte State) and oceanic islands (Muricy et al. 2011; Azevedo et al. 2017), Peru (Azevedo et al. 2015) and Martinique (Pérez et al. 2017).
