Description

 The growth form and colour of Hymeniacidon perleve varies depending upon shore exposure, from thin sheets on lower to mid shore (growing along crevices and fault lines), to massive flanged or turreted forms often found on the lower shore in wave sheltered locations and in the sublittoral where conditions are distinctly silty. Colour varies from yellow to orange to blood-red. Shore forms tend to be blood-red, whilst sublittoral forms tend to be pinkish-red.In the intertidal and shallow sublittoral more than one form can be detected, which may eventually be recognized as including more than one distinct species.

 Other species
Hymeniacidon kitchingi is the only other Hymeniacidon species from Western Europe. It is more thinly encrusting than Hymeniacidon perleve, and is beige-yellowish in colour. Close examination of the spicules of the endoskeleton may be required to distinguish other species.

 Usually an intertidal species found colonizing a variety of surfaces from exposed rocks and seaweed holdfasts to muddy gravel. Also present on sublittoral rocks in turbid water or variable salinity conditions. It appears to prefer slightly silty environments.

Crumb-of-bread sponge

The crumb-of-bread sponge, Hymeniacidon perlevis, is a species of sponge in the class demosponges.

Distribution[edit]

The crumb-of-bread sponge is found in the northern Atlantic Ocean, the Mediterranean sea and the Pacific Ocean, as well as around the southern African coast from the northern Cape to Port St Johns. It lives from the intertidal zone in tide pools to a maximum depth of about 15 meters (about 50 feet).

Description[edit]

The crumb-or-bread sponge is a thickly encrusting sponge with a glistening bumpy surface. Specimens found intertidally are bright yellow. Specimens from deeper water are darker. The oscula are scattered across the surface of the sponge and may be flush with the sponge surface or on raised mounds.[1]

Ecology[edit]

The form of the sponge is variable, depending on its environment. In sheltered areas, branched structures grow from the base. In areas with wave action the surface is convoluted or flat.[2]
