Towed cameras, ROVs, autonomous underwater vehicles (AUVs) or manned submersibles are ideal for sampling the fauna of these fragile habitats (see Chapters 12 and 13). Habitat heterogeneity is also observable on the abyssal plain, which is usually considered homo­ geneous. , 2009). Beside between‐habitat differences, deep‐sea communities may also show differences within the same habitat, due to patchiness related to variation in sedimentary carbon content, physical distur­ bance or micro‐habitat provision.
