Overview
Comprehensive Description
Biology
A little-known tropical shark found on the uppermost insular slopes (Ref. 13563) at depths of 250-475 m (Ref.58048). Feeds on cephalopods (Ref. 244). Viviparous, placental (Ref. 50449). Caught irregularly by the small-scale demersal longline fisheries operating in deepwater. Utilized for its meat and fins, but of limited value due to its small size (Ref.58048).

Justification
A small houndshark reported from northwestern Western Australia, Queensland and Vanuatu. Recorded from the continental slope at depths of 250 to 475 m. The species produces small litters of 4 to 5 young, but little else is known of its biology. It is of minor interest to fisheries although it is likely to be taken as bycatch in the small Australian Commonwealth managed North West Slope Trawl Fishery. More information is needed on its biology and abundance, particularly as it seems to be naturally rare.

Major Threats
Iago garricki is of minor interest to fisheries (Compagno and Niem 1999). It is likely to be taken as bycatch in the Australian Commonwealth managed North West Slope Trawl Fishery which operates at depths of >200 m off northwestern Western Australia. This fishery is small and no actual data on bycatch levels are available (Harris and Ward 1999).
