Notes: In The Bahamas it grows as light purple or greenish-grayish thin branches or aligned tubes; easily compressible. Lagoonal specimens may be similar to Callyspongia fallax Duchassaing & Michelotti, 1864, but C. pallida is much softer and its fiber networks of much smaller size. In other areas C. pallida is more massive with oscular or tubular mounds, and tends to be whitish. Pedro Alcolado (Cuba, pers. comm.) call this form Callyspongia arcesiosa de Laubenfels, 1936, as a distinct species from C. pallida. We have so far found only one form of soft Callyspongia and used C. pallida following van Soest (1980).
