Issue
The 3 subspecies were upraised at species rank, as provisionally accepted names, , until more works are conducted on T. acus susbepcies to fix their status.

Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 20 - 27; Spine anali: 0; Raggi anali molli: 20 - 24; Vertebre: 90 - 95. Diagnosis: body elongate; upper and lower jaws extremely long, forming a stout beak armed with very sharp teeth; gill rakers absent (Ref. 57228, 90102). Nostrils in depression before eyes (nasal pit); pelvic fins abdominal; 20-26 dorsal-fin rays; anal fin short, 9.7-11.7 times in body length; small, black lateral keel on either sides of caudal peduncle; caudal fin deeply forked (Ref. 57228).

Biologia     Glossario (es. epibenthic)

Inhabits oceanic and neritic waters (Ref. 26340). Feeds on small fishes. Oviparous (Ref. 205). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205). Although sold fresh and salted, its market is limited due to the green-colored flesh (Ref. 5217). Circumglobal in tropical seas and divisible into four subspecies (Ref 90102).
