Ciocalypta tyleri Bowerbank, 1873: 21 , pl. 4.

Material examined PONTA DO OURO • 1 dried sponge portion, with fistules, about 3× 3× 2 cm; 26°49′29.579″ S,

32°53′51.035″ E; Blacks ; 18 m deep; 13 Nov. 2015; Cerrano leg.; PdO16 .

Description

The sponge is massive, partially burrowing, with light yellow fistules ( Fig. 25A ) rising above the sediment. The dried sample is whitish, the body is rich in sediment, while the fistules are erect and fragile, with a rough surface.

SKELETON. In the body, it is formed by a confused reticulation, with loose tracts of oxeas ( Fig. 25B ). The fistules have a central axis of loose-packed oxeas from where tracts of spicules radiate towards the surface.

SPICULES. One size, 295–(351, 32.6)– 400 µm ×5.1–(7.8, 1.3)– 9.5 µm, of curved oxeas, sometimes bent in the middle ( Fig. 25C ).

Remarks

The presence of numerous finger-shaped and transparent fistulae with a central axis and the general structure of the skeleton characterize the genus Ciocalypta Bowerbank, 1862 . To date, there are 26 species of Ciocalypta described ( Van Soest et al. 2019). The examined sample fits the original description of Ciocalypta tyleri Bowerbank, 1873 from Port Elizabeth, South Africa, in the general structure and the spicule sizes.
