We went here one day when we had some snorkeling friends with us, and the water was too rough farther south (where our favorite dives are). This is the only place (in 5 weeks of diving) that we found some thermoclines. Our snorkeling friends noticed the water temperature variation also. Saw a scorpion fish, some spotted drum (adult and juvenile), a spotted moray, etc. Our snorkeling friends saw three squid.
