Spines and soft rays are different parts of a fin: the dorsal fin has both. The FAO account’s description of Trachichthyidae morphology also notes that pelvic fins have one normal spine and six or seven soft rays. That is a family-level description, rather than a count established specifically for every orange roughy. FAO species account
Does orange roughy have scales?
Yes. Its body is covered in small ctenoid scales, according to the Australian Museum. Scales along the lateral line—the sensory line running along the fish’s side—are enlarged compared with the other body scales, according to the New Zealand guide.

What is the ridge on its belly?
The belly has a row of 19–25 small, scute-like scales that form a ridge, as described in the 2011 New Zealand guide. These structures are part of the fish’s scaled body, not fins. The FAO account also discusses scutes in its description of Trachichthyidae morphology. New Zealand Ministry of Fisheries species guide · FAO species account
