This firm yellow sponge is roughly hemispherical and around 12 cm across. Like other species of the genus Acanthotetilla, it is characterized by the presence of distinctive spiny spicules called "megacanthoxeas". This sponge, however, differs from the other described species in that the megacanthoxeas exist in two distinctly different sizes as opposed to being uniform in size.
