A large Macrocystic kelp fall was observed on the Patton Escarpment being grazed upon by fragile pink urchins (Strongylocentrotus fragilis) at 728 meters (~2,388 feet). Many other invertebrate species and some fishes were observed to live in and around the kelp fall. Sea cucumbers (Pannychia sp.) and sea pens were more characteristic of the surrounding soft bottom community.
