We've seen a couple of sun fish around Catalina in the last couple of years. Judy saw one just outside of Avalon this weekend, and we saw one in the middle of the channel a couple of years age. The only other sun fish we've ever seen were in the Monterrey Aquarium and the So. Pacific. The SoCal waters are getting warmer.
Keep a good lookout, cause if you hit one, it'll tear out whatever is underwater. They're slow, solid fish.
