The spine has been reputed to be venomous, but no serious injuries have yet been reported. An international team of researchers has sequenced the genome of the elephant shark, a curious-looking fish with a snout that resembles the end of an elephant’s trunk. Elasmobranchii (the subclass that contains sharks and rays) evolved the distinct characteristics we associate with cartilaginous fishes, but the Holocephali class took a different evolutionary path.They are a member of the subclass Holocephali, commonly known as chimaeras - the only member of this group commonly found in South African wate… Their white flesh fillets are very popular with fish-and-chips restaurants in New Zealand and is sold as 'flake' or 'whitefish' in Australia.
