Introduction
Members of the Torpedinidae occur in all the oceans of the world; two genera and at least 22 species are recognised (Last & Stevens 2009, Nelson et al. 2016). In Australian waters, one species is represented, although previously three species were recognised (Last et al. 2016).
.
Like narcinids, torpedinids are sluggish bottom dwellers found from the intertidal zone to more than 1000 m. They are very thick in the body where the vertical columns of cells comprising the electric organs are located. The powerful electric shock generated by torpedo rays is used both for defence and to stun prey. The skin lacks denticles and the short tail lacks spines. Maximum size for the family is 1.8 m.
The torpedo rays have not been reviewed comprehensively. McKay (1966) and Carvalho et al. (2016) reviewed the Australian species. Last & Stevens (1994) and Compagno & Last (1999) placed the genus Hypnos in a separate monotypic family Hypnidae which we follow here. Hypnos was retained in the Torpedinidae by Nelson (2006) and Nelson et al 2016..
