Table 1.

Yields of silica spicules, filaments, and filament protein from Tethya aurantia

Material	Weight, g	Yield, %*
Sponge (wet)	20.0
Sponge (dry)	7.3	100
Spicules	5.5	75.3
Filaments	0.0058	0.11
Protein	0.0053	0.10

^*Yield was calculated relative to sponge dry weight as 100%. (Dry weight of the sponge was ca. 35% of the live wet weight).
