This genus is characterized by its unique teeth-like structures called abyssochelae, although they are not present in every species.

[2] Both groups have straight spicules and are covered in a layer of soft tissue with sticky microstrongyles protruding perpendicularly from the body, used to capture prey.

[3] Most carnivorous sponges lack an aquiferous system, meaning they cannot filter water to get their food.

[citation needed] In the deep sea, resources are sparse, so organisms tend to have clustered distribution.

These carnivorous sponges are usually found around nutrient hot spots like seamounts, and oceanic ridges.
