Congratulations Titus! You deserve it, you've been here for longer than most and you've been constantly promoting Steem all over the internet.
I'm also a little confused as to what exactly makes someone a dolphin/killer whale/whale. Seems like everyone has a different metric.
Here's a link to steemitboard.com where you can see your achievements and some stats from @arcange. According to this, you're status is dolphin atm. So am I.

By these stats, if you have more than 100,000 vests (50k sp) then you achieve killerwhale status, I think.
Anyways, always enjoy your investigations. Peace brother.
