Issue
Considered mostly as a subspecies in the literature. Therefore the upraise at species rank here is considered as a provisionally accepted name, until more works are conducted on T. acus susbepcies to fix their status.

背棘 (总数) : 0; 背的软条 (总数) : 24 - 27; 臀棘: 0; 臀鳍软条: 22 - 24; 脊椎骨: 90 - 95. Anterior part of dorsal fin with a low lobe, contained 10.5-13.3 times in body length; a distinct black lateral keel on caudal peduncle; caudal fin deeply forked. Juveniles have an elevated black lobe in the posterior part of the dorsal fin (Ref. 9682). Longer jaws with more numerous teeth and narrower caudal lobes than T. crocodilus (Ref. 37816).
背鳍前部有被包含 10.5-13.3个倍体长的一个低的叶; 一个明显的黑色侧龙骨在尾梗上; 尾鳍深深地分岔。 稚鱼在后面的部分背鳍中有一个升高的黑色叶。 (参考文献 9682) 超过 T. crocodilus 较长的颌部有众多的齿与较狭窄的尾叶。 (参考文献 37816)
Found in offshore and coastal waters. Feeds mainly on small fishes. Marketed mostly fresh. The flesh is of good quality (Ref. 9682). Oviparous (Ref. 205). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205).
发现于外海与沿岸水域了。 主要吃小鱼。 市场上大部份生鲜地销售。 肉是有好质量的。 (参考文献 9682) 卵生的.(参考文献 205) 卵可能被发现于在卵的表面上的卷须水依附于目标。 (参考文献 205)
