106. Haliclona bucina Tanita and Hoshino, 1989<br />
Description. This small vase-shaped sponge has a<br />
thin fistular stalk or basal fistular s<strong>to</strong>lons. Due <strong>to</strong> <strong>the</strong><br />
reticulation <strong>of</strong> single spicules <strong>the</strong>se <strong>sponges</strong> are only<br />
slightly elastic and consequently very fragile. Height is<br />
<strong>to</strong> 3 cm and width <strong>to</strong> 1 cm. Color in life is light brown<br />
<strong>to</strong> golden brown.<br />
Skeletal structure. There is a unispicular reticulation<br />
<strong>of</strong> oxeas (165–195 × 7–9 µm), slightly longer than those<br />
originally described.<br />
Zoogeographic distribution. Rare. In Alaska – central<br />
Aleutian Islands. Elsewhere – known only from Sagami<br />
Bay, Japan.<br />
Habitat. In Alaska – attached <strong>to</strong> <strong>the</strong> calcareous sponge<br />
Leucandra tuba at a depth <strong>of</strong> 145 m. Elsewhere – depths<br />
between 80 and 95 m.<br />
