Doesn’t do well in captivity, w/ 6.5 months being record time length at Monterey Bay Aquarium (how long 2nd one was there & 1st individual through program called Project White Shark). The aquarium has had 6 exhibited between 2004-2011, all either died or were released. Sharks were first housed in 4,000,000 gallon net pen for some time, then transferred to 3,200 gallon portable tank, eventually joining 1.2 million gallon Open Sea habitat. Program ended due to high resource intensity & casualties of tank mates.

    I’m really inspired together with your writing skills as neatly as with
    the layout on your weblog. Is this a paid subject matter or
    did you customize it yourself? Either way keep up the nice high quality writing, it’s rare to see
    a nice weblog like this one nowadays..

    Hey this is kind of of off topic but I was wanting to know if blogs use WYSIWYG editors or if you have to manually code with HTML.
    I’m starting a blog soon but have no coding experience so I wanted to get advice from someone with experience.
    Any help would be enormously appreciated!
