Ectyoplasia ferox (Duchassaing 1864) Especie incrustante con presencia de gran número de poros realzados de color amarillo. Estos forman series que llegan hasta el cuerpo principal, el cual tiene una textura similar a hule y coloración café.

Ectyoplasia ferox (Duchassaing 1864) This has numerous raised yellow pores running in series, set into the main, brown leathery and usually encrusting mass. Commonly, each exhalent pore develops into small cones. Sometimes these cones develop further into ramose structures. An older but commonly used name for this is Hemectyon ferox.

The marine sponge Ectyoplasia ferox produces antipredatory and allelopathic triterpenoid glycosides as part of its chemical defense repertoire against predators, competitors, and fouling organisms. These molecules are responsible for the pharmacological potential found in the glycosides present in this species.
