Systems
This species resides in shallow tropical waters along the coast and on coral reefs. H. trispeculare reaches a maximum size of 79 cm total length (TL) and is oviparous. Individuals are commonly observed under coral structures. Adults and juveniles probably feed on benthic invertebrates and small fishes similar to H. ocellatum. Little else is known about the biology of this species.

Justification
This little-known species is possibly an Australian endemic (it may also occur in Indonesia). It is not targeted by fisheries and is distributed over a reasonably large coastal range. These small sharks are unlikely to be significantly impacted as a bycatch species and at least a portion of the species? range is protected from fishing. This species may be utilized by the aquarium industry, but the extent of exploitation is unknown.
