A little confirmation from my recent trip to Kauai before I post to Flickr. I've gone as far as I can with my Hoover books and Keoki Stender's website.
Sheraton Caverns dive site, 10m deep, ~15-20cm in length
I have: Warty Frogfish (Antennarius maculatus) but Warty is supposedly not common in Hawaii??
Pyramid at the Point dive site (Niihau/Lehua), 20m deep, ~5cm in length
Pretty sure the shell on the left is Textile Cone Shell (Conus textile) but the snail on the right - some kind of Drupe??
Tunnels Shore Dive site, 2-3m deep in sand, ~2-3cm in length
I have Female Longtail Dragonet (Callionymus decoratus). Not sure. I only have this butt-shot, sadly
Thanks for any input
