PHYLUM :- PORIFERA (Pore bearing, cellular grade, asymmetrical or radially symmetrical.)

CLASS :- DEMOSPONGIAE (Skeleton of spongin fibres or siliceous spicules which are not six-rayed.)

ORDER :- Monaxonida (Spongin mayor may not be present; spicules monaxon.) 

GENUS :- Microciona

GEOGRAPHICAL DISTRIBUTION

  • Microciona prolifera is very common, in Long Island Sound and also present in South Carolina to Cape Cod.

GENERAL CHARACTERSTICS OF MICROCIONA​

  • In deep-sea water the colony becomes massive and develops upto 10 cm in total length.
  • It is bright red coloured. 
  • Sponge comprises of several finger like projections in ascending order. 
  • It has large spicules united by spongin into a regular network. 
  • It is largely used to study regeneration and reassociation experiments. 
  • Dissociated cells from same species reaggregate. Humphrey has shown that in this animal calcium and magnesium ions along with some cells surface are necessary for aggregation.
