Description

Live sponge irregularly massive ( Fig. 14 View Fig A–D). Color from light or vivid blue to brown; the surface is often covered by epibionths which hide the superficial sponge color. The samples preserved in alcohol are beige with a greenish shade. The surface is uneven, the consistence is tough and uncompressible.

SKELETON. Ectosome consisting of phyllotriaenes and strongyles organized in a layer with numerous rhabds ( Fig. 14 View Fig E–F). Choanosome formed by tetraclone desmas and brushes of strongyles ( Fig. 14 View Fig G–H).

SPICULES. Phyllotriaenes 80–(139.1)– 185 µm ( Fig. 14 View Fig E–F); desmas tuberculate and with rounded tips 125–(201.6)–300 × 15–20 µm ( Fig. 14 View Fig G–H); smooth and slightly curved strongyles ( Fig. 14I View Fig ), 275– (355, 77.2)– 530 µm × 4. 8–(6.25, 1.3)– 8 µm, often with slightly enlarged extremities; rhabds ( Fig. 14J View Fig ) are straight or bent in the middle and microspined, 8–(14.5)– 19 µm.

Remarks

This sponge is widespread in the studied area; it fits with the species Theonella timmi   as recently described by Samaai et al. (2019) from South Africa for its blue color, both interior and exterior, and for the shape and size of its spicules.
