Ecology

It is found under rocks or coral rubble, primarily on living reefs.[6] Minimum recorded depth is 0 m.[7] Maximum recorded depth is 33 m.[7] Defensive behavior consists of the unrolling of the mantle margins to expose bright white areas followed by swimming by contracting the body and mantle margin.[6] Species of the genus Hexabranchus prey on a variety of sponges.[6]
