Diagnosis
Encrusting to lobate or ramose. Surface smooth or extended into corrugate or spined projections. In life, superficial canals characteristically swollen and with a lighter-coloured lining. Skeletal arrangement is simple: irregular plumose bundles of megascleres, which tend to form loose brushes at the surface without forming a definite ectosomal skeleton. Spongin variably developed but may be considerable. Spicule complement rather variable, both among and within species. Basically, the two size categories of megascleres characteristic for the family are present, but these may be indistinguishable in some species or modified to strongyle-like spicules. Microscleres may include a full complement, then consisting of two categories of anchorate-unguiferate chelae and spined microxeas; frequently one or more of these may be absent or reduced. In extreme cases only reduced and modified megascleres may be found (Ectyobatzella form) and then assignment to Monanchora remains problematic.
