SIODFA vessels can use the Association's form for collection of occurrence data on deepwater sharks.  Identification of deepwater sharks is problematic and compounded by the use of different common names for the same species and the same name for different species.  It is recognized that the systematics of this group needs attention from appropriate elasmobranch taxonomists but as yet no source of funds has been found to enable this extremely important work to be undertaken.  One particular example is the confusion in naming between the Pacific sleeper shark (Somniosus pacificus) and the Southern sleeper shark (Somniosus antarcticus).  This shark tends to be robust to capture and skippers report that the same shark may be caught several times.

The following table lists the assumed species identity of deepwater sharks (and rays) taken as bycatch in the SIODFA fishery.
