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

ORDER :- AMPHIDISCOPHORA (Hexaster spicules absent and amphidisks present.)
GENUS :- Pheronema
GEOGRAPHICAL DISTRIBUTION
It is found in u.K., U.S.A., and Europe.
HABIT AND HABITAT
Pheronema is found on the bottom of sea. It is the commonest hexactinellid amphidiscophore adapted for deep-sea life

- Animal has a thick-walled cup or bowl-shaped body with the spongocoel opening above and with spicules in the form of tufts.
- Pleural tufts and long-twisted root tufts are present resembling glass wool.
