Picture courtesy of: Luc Faucompré
Biology
Benthopelagic over reef and sand. Found in pairs or small groups in deep rocky drop-offs.
Similar species
Histiopterus typus (Temminck & Schlegel, 1844) - Reported from Red Sea; Indo-West Pacific: Eastern Cape and KwaZulu-Natal (South Africa), East Africa, Gulf of Aden, Socotra (Yemen), Comoro Islands, Réunion (western Mascarenes) and Persian Gulf east to Philippines and New Ireland (Papua New Guinea), north to Korea and central Japan, south to northern Australia. Evistias acutirostris differs from the similar Histiopterus typus in having a deeper, striped body, and short dorsal and anal-fin spines (vs. third and fourth dorsal, and third anal-fin spines elongate in Histiopterus).

Description
Dorsal spines (total): 4-5; Dorsal soft rays (total): 26-28; Anal spines: 3-4; Anal soft rays: 11-14; Pectoral fin rays: 16-18; Pelvic fin rays: I,5; Lateral line pores: 58-77; Vertebrae: 13 + 14; Gill rakers: 5-7 + 14-17 (range: 20-23). Body very deep, broadly rounded below dorsal-fin rays, snout slightly elongate, robust in adults, lips and chin with dense ‘whisker-like’ villi, those on chin very long and sometimes divided; Dorsal fin tall, sail-like with a convex posterior margin; Dorsal spines stout, progressively increasing in length; Anteriormost dorsal-fin rays much longer than posteriormost fin spine. Max. length: 90.0 cm TL. Depth range: 18 - 193 m.
Color
Five dark bands on the body, and yellow dorsal, anal and caudal fins.
Etymology
Evistias: from Greek prefix, eû = well + from Greek, histion = sail. Referring to tall and sail-like dorsal fin.
acutirostris: from Latin, acutus = sharp + from Latin, rostrum = snout. Referring to elongated snout.
