Remarks A pelagic species (Ref. 26340) 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 (Ref. 11889). 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. A carnivore (Ref. 9137).
