I have seen one, and it was on a school trip in 2004 in Durban where they brought one of the caught great White Sharks and dissected it in front of us kids for "educational" purposes, basically showing us what it has in its stomach, how it has infinite teeth. They use these "educational" dissections as justification for draglines and nets unfortunately.
I actually wrote an email to the new Minister of Forestry, Fisheries and the Environment: Dr Dion George, giving my two cents like how draglines and nets are outdated and dangerous to the shark population, how much better methods now exist. I only received an email saying they noted my concern. At least there are organisations really trying to save not only the great White shark but many other marine animals
As a dog person I see cats as being apathetic towards their owners. Oh you arrived from work or a 3 month holiday, well I do not really care.
Where my dogs in my mind, which is based entirely on my feelings, will take a bullet for me if they could.
