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.

экология
морской; пресноводный; солоноватоводный ассоциированный с рифами; мигрирует в океане (Ref. 51243); пределы глубины 0 - 1 m (Ref. 58302). Tropical; 32°N - 28°S
Indo-Pacific: East Africa (Ref. 3130) to the central and south Pacific. Eastern Central Pacific: oceanic islands such as the Revillagigedo, Clipperton and Cocos (Ref. 9279).
Size / Вес / Возраст
Maturity: Lm ? range ? - ? cm
Max length : 100.0 cm TL самец/пол неопределен; (Ref. 9137); common length : 115 cm TL самец/пол неопределен; (Ref. 5450)
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 24 - 27; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 22 - 24; позвонки: 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).
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).
