Just published this short video of the most amazing school of fish I’ve encountered while diving. Called salema (Xenistius californenis), resources tell me they are common in southern California. I hadn’t recalled seeing them before. When researching them I discovered some videos of them at the Galapagos Islands. Quite a range!
I made this video as partial fulfillment for my advanced open water scuba certification. Visibility was about average. For you non-divers, the viz is always better than the video shows.
