Comprehensive Description

Description

This demosponge species is lobate to tubular in shape, with tubes measuring up to 6.5 cm in height. Tubes may branch or reticulate to form a network.

Spicules form a loose network, with overall skeletal structure highly variable. Color variants include light tan, orange-brown, or red. For complete description, see Lee et al., 2007.
