Axinella tenuidigitata   Dendy,  1905 (Sponge)
Organism information awaits expert curation
Class: Demospongiae

Color: Pale wax-yellow (in spirit)

The single specimen is a small massive sponge of short, thick, irregularly cylindrical form, attached by a broad base below and strongly convex on the upper surface, from which a number of slender, elongated, finger-like processes are given off. Surface uneven and irregularly hispid, especially on the digitiform processes; in part minutely and irregularly conulose and in part covered by a distinct, sub-glabrous, translucent dermal membrane. The digitiform processes are solid and they may unite with one another. Vents apparently small and scattered between the processes. Texture hard and compact. Height of body about 20 millimeters diameter about 15 millimeters; length of processes, of which there are about half a dozen, about 11 millimeters., with a diameter of not much more than 1 millimeter. The skeleton in the body of the sponge consists of an irregular reticulation of long styli, which as they approach the surface, arrange themselves in loose, irregular, plumose columns. The digitiform processes are composed each almost entirely of a dense axis of similar spicules closely crowded together and placed longitudinally, with a few spicules projecting outwards beyond the surface, so as to give rise to its hispid character.
Spicules: Apparently all stylote and all long, but varying much in thickness; usually only very slightly curved (towards the base), but sometimes crooked; broadly rounded off at the base, which may be somewhat narrower than the middle part of the spicule, and gradually and sharply pointed at the apex. The stouter forms measure about 1.18 millimeter by 0.0328 millimeter. In the digitiform processes they are a good deal more slender, and slender forms also occur intermingled with the stout ones in the body of the sponge.
