Any of the spikefishes of the genus Parahollardia.
Spotted spikefishes and jambeaus are diamond shaped, about as long as they are high, with the greatest depth occurring at the tips of the stout first dorsal and anal spines, near the midbody. The small caudal fin is broadly rounded.
From Middle English iambeau(s) (compare jamber), from an Anglo-Norman [Term?] derivative of Old French jambe (“leg”): compare Old French jambiere. See jamb (noun). Compare lamboy(s).
