Description
The live sponge is massive, with rounded conules covering the surface (
Fig. 22A
). The color is redorange. The fragments preserved in alcohol are beige in color; they have a digitate-conulose surface and a very firm consistence.
SKELETON. The ectosome consists of a paratangential layer of thin styles (
Fig. 22B
). The choanosome (
Fig. 22C
) is made by a reticulation of multispicular primary fibers,
70–125 µm
in section, and secondary fibers,
23–35 µm
, forming irregularly rounded meshes around
150 µm
wide. The fibers have a core of styles and are echinated by acanthostyles.
SPICULES. Slightly curved and smooth styles (
Fig. 22D
), sometimes straight, 145–(176.5, 21.4)–
210 µm
× 6–(7, 1.1)–
9.5 µm
; longer and straight subtylote styles (
Fig. 22E
), microspined or smooth on the head, 198.5–(230, 15.5)–
250 µm
×4.5–(6.5, 0.8)–
7.5 µm
; subtylote acanthostyles (
Fig. 22F
), with smooth neck, 47.5–(51, 4.9)–
72.5 µm
; very thin toxas (
Fig. 22G
), bent in the middle,
143–181 µm
; palmate isochelae (
Fig. 22H
)
11.3–14.6 µm
.
Remarks
The specimens fit the original description of
Clathria
(
Thalysias
)
vulpina
(
Lamarck, 1814
)
from
Australia
. The species has already been found in the area (
Thomas 1979
). On the specimen PO3, the hydroid
Zyzzyzus warreni
Calder, 1988
(Class
Hydrozoa
, Phylum Cnidaria) grew.
