Description 347-353
Marine sponges are a highly diversified group of invertebrates
(phylum Porifera) which inhabit different substrates in the coastal
regions of the world. These sponges play an important role in the
food web and provide a protected and nutrient-rich habitat for a
variety of organisms. This is the first report on the re-description
of two marine sponges belonging to the class Demospongiae,
order Haplosclerida inhabiting the coastal waters of Karachi
(Pakistan; Northern Arabian Sea). Callyspongia (Cladochalina)
fibrosa (Ridley and Dendy, 1886) (Family Callyspongiidae) was
collected from Churna Island at 7 m depth through SCUBA diving
and Haliclona (Soestella) hornelli (Dendy, 1916) (Family
Chalinidae) was collected from the rock pools of Buleji rocky
ledge. The skeletal framework of both sponges was observed in
light and scanning electron microscope. The spicules of C. (C.)
fibrosa were smooth and densely packed with thick ectosomal and
choanosomal fibres. The choanosomal skeleton of H. (S.) hornelli
was sub-anisotropic, forming a reticulation of meshes with
unispicular and paucispicular lines, and its spicules were slender
megascleres while microscleres absent. H. (S.) hornelli is assigned
to the subgenus Soestella of the genus Haliclona.
