Picked up an Aquatica housing last year to take out free diving. Still getting used to it, and haven't started using my strobes yet, but it's been fun so far.
Here's a sea nettle (Chrysaora fuscescens) off Lover's Point yesterday. They disappeared for a while, but with cold upwelling they've come back in surprising numbers. They do sting, but are usually easy to avoid (though there are times they fill up the entire water column!).
