The Ornate Dogfish (Centroscyllium ornatum) is a poorly known species of deepwater dogfish, occurring at depths of 521–1,262 m on the upper continental slopes off India in the Arabian Sea and the Bay of Bengal. Its wide depth distribution probably provides some refuge beyond current fishing pressure, however, any expansion of deepwater fisheries in this area could impact on the species given its restricted range. This species is known from very few specimens and insufficient information is available to assess it beyond Data Deficient at present.

|Current Population Trend:||Unknown|
|Habitat and Ecology:||A deepwater species found on the upper continental slope, near the seabed at depths of 521–1,262 m (Compagno et al. 2005). Very little is known of the biology. Maximum total length (TL) is reported at 30 cm, although the specimen may have been immature (Compagno 1984). Reproduction is presumably ovoviviparous (Compagno et al. 2005).|
Compagno et al. (2005) note that this species is apparently of no interest to fisheries at present. Very little is known of the interaction of this species with fisheries throughout its range. India has at least 100 deep-sea fishing vessels (FAO 2007), but specific information on deepsea fisheries in this area is not available.
The wide depth distribution of the species may provide some refuge beyond current fishing pressure, however the situation should be monitored as fisheries expand to greater depths.
|Conservation Actions:||None in place. Like many deeper water species more information on biology, ecology and importance in fisheries are required to assess future conservation needs.|
