Crikey, I was stumped. So I headed for the WWM site – cos those that keep rays are sure to understand them best- and I found this little gem about the barb of the ray that got Steve Irwin “Mmm, likely ten to fifteen cm…. do lose these, regenerate… is actually a “sheath” that covers the poison-secreting mechanism… Bob Fenner” I have read lots of conflicting info. about ray barbs. Please tell me more this about regeneration and about the poison/venom too. Vicki
