Tony Baker from Great White Shark Tours (https://www.facebook.com/Great.White.Shark.Tours?fref=ts ) said, "On the afternoon of 21st March, while divers were in the viewing cage, a young great white shark of approximately 2 ½ m in length came up to the cage and stuck its snout and head into the viewing gap for about 5 seconds. No injury to any diver or shark occurred. The cage is built to industry standards and is inspected annually by the Maritime Authority. The viewing gap was immediately reduced by approximately 10%. This incident has been reported to the Great White Protection Foundation of which we are a member. There wasn't any sloppy bait handling, just a shark that decided to rocket towards the cage for no reason!! It may have been spooked by a bigger shark below...”

11th March 2013 was a landmark moment for marine conservation, with five more shark species and manta rays all being listed on Appendix II of CITES. The five species are the oceanic white tip, porbeagle and three hammerhead species, which join the whale shark, white shark and basking shark already on Appendix II.

According to the web page found at http://news.yahoo.com/kenya-whale-shark-safari-swims-controversy-115314986.html , “a new marine enclosure (in Kenya) will allow holidaymakers to snorkel with live whale sharks. Organisers of the Indian Ocean sea park say the €100 ticket price ($134 USD) will fund schemes to stop the docile fish from being wiped out. But a vocal group of conservationists says it is cruel and unnecessary to catch and exhibit animals, and wants to stop the scheme, saying it puts money before animal welfare. Organisers have dismissed critics as "over-emotional eco-zealots". The heated debate raises a question that splits conservationists: whether showcasing captive animals advances or hinders their efforts.”

A documentary DVD mentioned that mako sharks swim some 2000km per month in search of prey. This was certainly backed up by Morry the mako who swam some 15,700km in 7 months after being tagged off of Port MacDonnell, South Australia on 5th June 2012. The 2m-long male mako shark swam to Christmas Island in the Indian Ocean and back again in those 7 months. He had returned to within 200km of where he was tagged in south-eastern SA by 16th February 2013.
It seems that when Prince William was visiting Australia recently, CSIRO offered him its own book, “Sharks and Rays of Australia” by Peter Last & John Stevens (illustrated by Roger Swainston).

Indonesia has announced a new shark and manta ray sanctuary, the first to protect the species in the rich marine ecosystem of the Coral Triangle, known as the "Amazon of the ocean". Environmentalists on Wednesday welcomed the creation of the 46,000-square-kilometre protection zone, in an area at risk from both overfishing and climate change. The local government in Raja Ampat on the western tip of New Guinea island announced the move this week, issuing local regulations to ban the finning and fishing of sharks in the area, a tourist destination popular with divers. Meanwhile, Queensland researchers have spotted an unusually large group of manta rays in a feeding frenzy near Lady Elliot Island. University of Queensland researcher Dr Kathy Townsend believes up to 150 manta rays were feeding in the area last month. She said thephenomenon was a result of recent flooding in Bundaberg, with excess levels of water sending a surge of nutrients into the ocean, leading to a spike in plankton.

According to David Whysharksmatter Shiffman "A new study has estimated the total global shark mortality for the first time, and came up with a figure of between 63 and 273 million sharks a year.
