132 Professional Paper NMFS 12 111. Haliclona sp. 1 Description. This sponge is massively encrusting or cushion-shaped. Oscula are deep and crater-shaped. Surface is slightly rough; consistency is soft and fragile. Diameter is to about 10 cm. Color in life is light brown or golden brown. Skeletal structure. There is a choanosomal arrangement of oxeas (160–220 × 10–15 µm) in paucispicular tracts connected by single spicules. Zoogeographic distribution. Uncommon. In Alaska – central Aleutian Islands and Bering Sea. Habitat. Attached to cobbles and pebbles at depths between 150 and 160 m. Remarks. This species might represent an undescribed species. Photo. 1) Specimen collected at a depth of 155 m in the central Aleutian Islands. Grid marks are 1 cm 2 .
112. Haliclona sp. 2 Description. This sponge is flabellate; single- or multiplaned. Oscula are conspicuous, slightly elevated and scattered over the entire surface. It is extremely slimy, even in preservative. Consistency is very soft and elastic. Height and width are to 20 cm. Color in life is yellowish brown to light brown, but appears characteristically white in situ. Skeletal structure. Ectosomal tangential unispicular reticulation is strengthened by large quantities of spongin which covers the sponge like a perforated plate. Choanosomal paucispicular tracts are connected by single spicules to unispicular reticulation of oxeas (180–230 × 5–12 µm). Zoogeographic distribution. In Alaska – locally abundant in central Aleutian Islands. Habitat. Attached principally to bedrock, but occasionally to boulders and cobbles at depths between 74 and 195 m; more common at depths shallower than 120 m. Remarks. This species might represent an undescribed species. It is similar in growth form to Haliclona cinerea and displays the slime strands previously regarded as diagnostic for the species. However, H. cinerea has smaller oxeas than this species and is known only from shallow waters of the Celtic Seas Region of the North Atlantic Ocean. This species may be preyed upon by the blood star (Henricia sp.). Photos. 1) Specimen collected at a depth of 80 m in the central Aleutian Islands. Grid marks are 1 cm 2 . 2) Specimen (right) observed at 92 m in the central Aleutian Islands. 133
