Like most top predators, sharks feed on the sick and weak, thereby keeping the schools of fish on which they feed healthy. It is several times deadlier than cyanide. Fish eyes are similar to those of terrestrial vertebrates like birds and mammals, but have a more spherical lens. Market surveys in 2001 indicated that catch was under-reported in official statistics, and that significant quantities of meat were likely being imported through unofficial channels (Chen and Phipps 2002).

While large numbers are taken as bycatch in the United States shrimp trawling industry and grouper longline fishery, it is a targeted commercial species that accounts for about 30 percent of the total catch in the shark longline fishery. Greyish upper body, sometimes with a brownish tinge and white belly with distinctive, notched tail. A subset of the Seychelles dataset, comprising records from 2004 to 2009, was modelled to produce an abundance estimate of 469 to 557 sharks from that area (Brooks et al. 2010).
