1 spec.
General distribution
Indo-West Pacific but not yet reported from the Middle East and the Indian subcontinent.
Remarks
This species grows to a very large size (up to
600 mm
) and is said to be white or black speckled with white (
Rowe and Doty, 1977
). The single eviscerated specimen is 245 x
145 mm
, black with greyish-white patches dorsally and grey ventrally. The dorsal (
Figure 11A
) and ventral table discs (
Figure 11C
) are respectively
75– 109 µm
and
57–86 µm
, while the respective buttons are
66–95 µm
(
Figure 11B
) and
65–127 µm
(
Figure 11D
). The papillae rods measure
136–306 µm
, the tubefeet rods and/or plates (
Figure 11E
)
238–386 µm
and the tentacle rods (
Figure 11F
)
30–224 µm
.
Thandar (1984)
doubted
James and Pearse’s (1969)
record of this species from
KZN
but, according to collectors from the Durban Oceanographic Institute, it is well established in northern
KZN
, especially on the Sodwana reefs. It has long been known from
Zanzibar
but has yet to be reported from
Mozambique
.
