Its mantle is covered in small spiculate papillae (caryophyllidia) which are characteristic of that genus.
The pattern and density of black spicules is variable. The most common colour form has the rings occupying about one-quarter of the area of the mantle.
There are specimens occasionally where the rings are reduced in size so the mantle is almost pure white,
whilst other specimens had the rings on the mantle so large that they virtually coalesced.
There are similar black or brown rings on the upper surface of the tail.
In juvenile form the black spots are in fact open rings and as they grow the other apparent spots will also expand in size and become black rings.
J.funebris is a sponge feeder. It seems that it eats different sponge species. Nuweiba, Gulf of Aqaba, Egypt.
