Ecology Summary - Tylosurus crocodilus

Ngôn ngữ:

Thông tin chủ yếu	Blaber, S.J.M., 1980
Các chú thích	A pelagic species (Refs. 26340, 9773) found over lagoon and seaward reefs. Solitary or in small groups (Ref. 11889). Present in seagrass beds at adult stage (Ref. 41878). Feeds on fishes (Refs. 11889, 9773). Oviparous (Ref. 205). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205). Feared by fishers because they can cause puncture wounds with their sharp snouts when jumping out of the water, e.g. when alarmed or attracted to lights at night. Carnivorous (Refs. 9137, 9773). Caught by casting or trolling surface or near-surface lures; also with purse seines and drift nets. Marketed mostly fresh (Ref. 9682). Inhabits coastal waters (Ref. 9773).
