Variability in the Sponge Phyllospongia foliascene Populations from Coastal Areas of Iligan City

Abstract

Morphological variability in the sponge, Phyllospo~1gia foliascence collected from different localities along the coastal areas of Iligan Bay was determined. Resemblance was determined using cluster analysis. Variability was correlated with the distribution pattern and some physico-chemical factors in the sampling sites.
