Type locality: east coast of USA (from Cape Hatteras to Nova Scotia) .

See: A.M. Clark & Downey (1992).

Occurrence: North Atlantic, in the west, from the US east coast to the Gulf of Mexico (A.M. Clark & Downey 1992); in the east it is reported from the Porcupine Abyssal Plain (SW of Ireland; Howell et al. 2003) and the Bay of Biscay ( Cherbonnier & Sibuet 1972) to SW Africa ( Sibuet 1975), along the Mid-Atlantic Ridge from the Charlie- Gibbs Fracture Zone to the Azores ( Dilman 2008). The subspecies D. grandis nobilis Sladen, 1889 is restricted to the Southwest Atlantic (A.M. Clark & Downey 1992).

Depth: 1,000 –5,124 m ( Dilman 2014); AZO: 2,954 –5,005 m ( Koehler 1909, Dilman 2008).

Habitat: soft sediments, from mud to ooze; predator (e.g., on other echinoderms) and scavenger, ingesting sediment ( Howell et al. 2003).

Larval stage: planktotrophic ( Tyler et al. 1990).

Remarks: when revising Dytaster from the Atlantic, A.M. Clark & Downey (1992) reunite the following records from the Azores under the name Dytaster grandis grandis : D. biserialis described by Sladen (1889) on the basis of material collected by H.M.S. Challenger (sta 79: 36°21’N, 23°31’W, 3,706 m), D. agassizi and D. rigidus both reported by Koehler (1909) based on specimens collected by Princesse Alice.
