FIGURE 17. Dysidea kenkriegeri n in New species of sponges (Porifera, Demospongiae) from the Aleutian Islands and Gulf of Alaska

FIGURE 17. Dysidea kenkriegeri n. sp. A. Holotype. Square is 1cm. B. View from above showing openings of tubes. Square is 1 cm. C. Section through tube. Square is 1cm. D. Section perpendicular to surface. Surface is on the left. Below the surface the reticulation of spongin fibers cored with foreign material is denser than in the deeper parts (upper right). Scale bar is 500 µm. E. Reticulation of spongin fibers just below the ectosome, clear spongin and coring sediment clearly visible. Scale bar is 200 µm. F. Ascending spongin fibers and connecting fibres are loaded with foreign material. Scale bar is 200 µm.
