The Deepwater sicklefin houndshark, also known as the darksnout houndshark, are known from only a few specimens from the Coral Sea off Queensland, Australia at depths of 225 to 400 m.
Biology and Behaviour
There is very little known of the biology of deepwater sicklefin houndsharks.
Reproduction and Lifespan
Deepwater sicklefin houndsharks are ovoviviparous. A 60 cm immature male was caught, therefore, deepwater sicklefin houndsharks presumably can grow longer than that.
Conservation and Tourism
The IUCN lists deepwater sicklefin houndsharks as data deficient because more information is needed to assess this species.
It is unknown if this species is used or traded, bu they may possibly be caught as bycatch from trawl and line fisheries that operate off north Queensland.
