Summary of the General linear model (GLM) fitted to the data to analyse the relationship between the environmental variables in relation to the total endobiotic abundance of the sponge Sarcotragus spinosulus. Depth = Maximum depth; Distance = Distance from the shore; Temperature = Average temperature at depth and Salinity; ‘*’ = indicates 95% significance.
